Top 10 Interesting Glitches in Pokemon Red/Blue

Came up with this idea while I was making the Magikarp videos. So many cool glitches in Red and Blue, and a lot of them are really fascinating! Let me know if you learned about any glitches you didn't know about already.
Note: some of these glitches are only in the NTSC versions of the game and many are Red/Blue only.

[@spacet1me]

Cheating and hacking in Pokemon Red was what got me into the IT field today and why I work in cybersecurity. The thrill of that kinda catapulted my passion and motivation towards the future as tech matured and grew. The only one I specifically remember is the MissingNo going up and down the shore line glitch / item duplication. I remember a friend taught me on the bus ride to summer camp during one summer when I was like 9yrs old lol. Loved the vid, some of the glitches were eh, but yea the top ones were awesome.

[@zacklightman9055]

Honestly the same stuff amazed me as a kid and still amazed me as an adult today obviously since I’m watching this video. I want to get into coding and programming etc and replaying my old Pokémon games recents is a huge part of that. Do you think you could take a minute to explain a little bit more about how you got into the fields you are in today and how a fellow Pokémon glitch-inspired fan might get into something similar?

[@FakeAssHandsomeMcGee_]

They probably have glitches because the programmers did not write unit tests. Always write your tests. jk.

[@jfb-]

How the Brock Through Walls glitch works, is that when you talk to that trainer, the game searches for your coordinates to see what path you have to take. But as you're not supposed to be able to talk to him from the right, your coordinates won't be where the game was expecting the coordinates to be, so it will just keep looking. Normally, it keeps looking forever which is why it soft locks. But if you have moves with the right PP, the PP values will actually be the coordinates the game is looking for, so the data after that will be interpreted as a path you're supposed to follow. But its a glitched path that happens to let you walk through walls.

[@Banzybanz]

5:25 An easy way to explain and understand this is by a mechanical odometer. If you roll back from 000000, you get to 999999, because there are no negative numbers on the odometer. It's the same with XP. XP is supposed to be a positive number only. When the formula gives out a negative number, the game interprets it as a very large positive number.

[@WillsMyth1987]

There is a glitch in which you don't have to set something up. Basically, if you go to any gym and try to fish or surf on the statues inside of any gym. It will just let you do that for no reason at all.

[@tusk4812]

I was waiting for you to mention the Mew glitch, and ofc it comes last lol. I was actually so lucky because I thought I had beaten every trainer but it turned out the one trainer I needed to fight in order to capture Mew was still uncontested. My excitement when I went and actually fought the trainer, then followed the steps exactly to where i needed to go to start fighting Mew, and the battle screen started.... Oh my god that feeling was so good.

[@HellHathNoFuryAtAll8]

As long as you have a long-range trainer, you can do the glitch as often as you like. Just have a Pokemon with a special stat of 21. Initiate the trainer-fly glitch, fight any trainer (can use Elite 4 if all other trainers are defeated. Must use PC to save by changing boxes and restart so you can talk to the E4 trainers). Then find a Ditto and have it transform into your Pokemon with a special stat of 21. You can abuse level underflow if you want by using 6 Growls on the transformed Pokemon before defeating it or running and get the level 1 Mew upon returning to the long range trainer’s route. If you do the level 1 Mew encounter, be sure you have space in your party. If it’s sent to your box, you can never withdraw it while it’s level 1.

[@19RyanTheLion91]

If you've defeated that certain trainer you could always use the ditto glitch to get Mew, or the 8F/wsm glitch to get as many Mew's as you want. You can even use a different variant of the 8F/wsm glitch to change Mew's ID to GF 22796 so you can transfer it to Pokémon Bank, the same glitch can also make it shiny. I currently have a shiny Mew in Shield using said glitch.

Wow! I always hate hearing about the exact same glitches over and over whenever I want to learn something new, and I was hoping that you wouldn't have the Missingno glitch here, but even though you did, I was stunned to know about those other glitches, and even how they worked, and it was really enjoyable to watch:) thank you for uploading this video😊

[@PokeMaster22222]

The reason why the SS Anne's still there is because it's a fundamental part of the Vermilion Dock map, and they likely didn't include a version without the ship (because it'd be pointless and take up valuable memory). As a result, should you manage to re-enter the map despite the invisible flag wall, the boat will always be there. Also, my favourite glitch? Transform + Mirror Move - should you use Mirror Move while Transformed, you'll be stuck with a blank move that DOES have PP, but cannot be depleted, thereby preventing Ditto (or Mew) from using Struggle. There's also no way to fix it, apart from Transforming into a Mirror Move Pokémon and hoping Mirror Move occupies the exact same glitched slot, then using all of its PP.

[@chrisruskai9341]

The experience one is because negative numbers in binary are encoded using the Two's Complement. Basically, you use the left-most bit as the pos/neg sign and then the rest of the bits represent the number. For example, when dealing with signed numbers, (signed) 010 = +2 110 = -2 (unsigned) 010 = 2 110 = 6 However, since the developers never intended for there to be negative experience, the binary representing the experience gained from a battle is likely read by the game as an unsigned number and since the left-most bit is 1, that makes the unsigned equivalent a really large integer.

[@keegankoeneman5940]

There are alot of really powerful glitches like the basic item dupe glitch and Data mod glitches like item underflow and ACE with things like super glitch and 8F, but the most interesting Imo is Pokemon merging. I guess you could do it with 8F, but back in the day it was always so fun to make hybrids of my favourite mons, especially if one of them was a glitch mon with a cool color pallet/ beast stats.

[@kylianthehylian]

I remember the invisible PC thing being highlighted in an issue of Nintendo Power, but when Nintendo was asked about the Missingno glitch it was vehemently denied lol

[@AlexTenThousand]

The exp glitch was the reason why pokémon were always born at level 5 up until Gen IV, since the glitch was seemingly brought over to Gold, Silver and Crystal given the re-used code, and Game Freak allegedly couldn't test if the same glitch would repeat in Gen III games despite being built upon entirely new code, so they just "skipped" a generation to implement the change.

[@kellygymnastt]

wow. as someone who had for sure seen them all, I never even heard of item underflow! all the others I've seen countless times but that one was new to me. Nice video! It's crazy that theres so many glitches you couldn't even list them all (i.e. save corruption to beat the game in 1 minute)

[@Sener]

Excellent, informative well constructed video! I didn't know about most of these!

[@cmoneyAZ]

The reason the experience/item underflow works that way is because the game uses some sort of circular indexing system like a circular queue that when it reaches the very end it wraps back to the first, so in theory if you want over the max amount of xp or items it could drop you back to one, that's why the xp is so high, so that normally a trainer could never get that much xp. So therefore if you go backwards in the queue it's going to bring you to the end of it.

[@Omio9999]

Close, but not quite it either. Numbers stored in memory were unsigned - more on that later, when I explain negative numbers - back in the GB and NES era, and was often the case in the SNES era too (though some cases did differ, but I digress). Numbers are stored with only a certain number of bits, and for the experience counter, this number is a 24-bit (or 3-byte) counter. When you have a level 1 Pokémon in Gen 1, it has 0 XP (In raw binary, 00000000 00000000 00000000). Thanks to it gaining negative XP, the XP is "added" like normal, and when the subtraction is performed, it assumes that the operation is valid, and the result is that it trudges on as if it had 16, 777,217 XP (That's [00000001] 00000000 00000000 00000000). The result is an underflow, as it applies the bitwise operation, and arrives at the over-16-million number that results in instant level 100(the details change mildly, because it's like 0+(-63 + whatever normal XP you get from the battle) but that's a nit-pick). The safeguard would be to have a signed integer, where you only use all but 1 bit of the number's normal space for counting, and one bit to denote if a value is negative, or positive. This is me using as close to layman's terms as I can while still being accurate to what's going on.

To me the most entertaining glitch in gen1 is how you can learn clone a pokemon to another pokemon. E.G you can have a pikachu with lapras stats and movepool.

[@lazula]

Here's a bit more of an in-depth explanation of integer underflow: Gen 1 pokemon games store experience values as *unsigned integers*. In my example, I'm going to simplify it by assuming that we're working with 4 bits. A 4 bit unsigned integer can store 16 different values(base 2^4 digits), from 0 to 15, which is equal to the numbers 0000 to 1111 in binary/base 2. If we were working with *signed integers*, it would be from -7 to 7, using the 8 bit to instead mark whether the number is positive or negative. In the case of tracking experience, negative numbers are unnecessary, so an unsigned integer is used. So, what happens if we try to create a negative number when working with an unsigned integer? Obviously we won't get one because it's impossible, so what happens instead? The numbers simply loop back around, hence "underflow" or "overflow" if going the other way. 0000 -0001 =1111 In this example, I simply subtracted 1 from 0. Instead of getting -1, we get 15. You might be looking at the equation and wondering why this works. The simple answer is that to the computer, 0000 to 1111 are the only values that exist for this number. Taking variable names from C's limits.h, let's call 0 UINT_MIN and 15 UINT_MAX. UINT_MIN-1 is equal to UINT_MAX, as shown above. The reverse is also true, as UINT_MAX+1 will resolve to UINT_MIN, which is why adding 1 to an 8-bit unsigned integer equal to 255 (11111111) will give you 0 instead of 256. Some processors clamp values and prevent over/underflow by simply making adding anything to UINT_MAX resolve to UINT_MAX. A perfect example of an unsigned 8-bit integer overflow is Styder7x's "Cracking a Frozen Lake 258 Times is Perfectly Acceptable". Signed integers are usually handled differently. Their behavior when doing calculations that would exceed INT_MAX or go below INT_MIN are very dependent on the language in use. Ada raises a Constraint_Error, Java will have normal overflow behavior going from INT_MAX to INT_MIN, and Python 2 converts the number to a long. I hope that helped some people who may have been a little confused about how experience/integer underflow works! This isn't anywhere near an exhaustive explanation since over/underflow is a result of many properties of computing and involves a lot of different environmental conditions; I'm just trying to clarify why it happens. Feel free to ask questions or point out anything I missed.

Back in the day when R/B were new the Old Man/ Safari zone/ Missingno / Item dupe glitches were common knowledge and often used. That's why they were patched in yellow. The other glitches came later afaik. I was even part of a group who was brute force testing every possible name to see if it was possible to get Mew on cinnibar. We eventually concluded that it wasn't. Trainer fly glitch came later and handed out mews like candy. I don't know how much later, but I played R / B at release and only heard of trainer fly a few years ago

[@187mrsmith]

The Mew one is the best one cuz you can get it early and as soon as it gets up to about level 20 it's super strong it learns mega Punch and then literally almost knocks anything out!

[@seanwetrich8299]

I always used the "missingno glitch" to capture a kangaskhan that can learn fly. If you encounter the glitch pokemon that is just "m," you can catch it. You have to have an empty space on your team or the game will crash when you try to withdraw it. It will have the moves water gun x2 and sky attack. You can teach it to fly. After teaching it to fly, give it a rare candy, and watch it evolve into kangaskhan. After evolving it, you can then teach it surf, strength, and cut to be your HM slave. I always try to get the level 0 version of the "m" pokemon, so that way my Kangaskhan will be level 1. Hope this helps.

The brock thru walls glitch is made with how the game gets data for the paths. The moves and the moves pp that bulbasaur has indicates the player coordinates you have when you perform this glitch, and the rest of the moves indicate a path that lets you walk thru walls. Also while youre following a path and your controls are locked, you can go through walls so thats sorta how it works.

Let me know if you can't see the link for some reason. The video title is: Pokemon Glitch Exhibition by Shenanagans in 25:00 - Awesome Games Done Quick 2016 - Part 130 starts at 23:55

[@megagustman]

Sato Yup could see it,thanks for the video it was awesome!.

[@SeraidenAF]

It was editd though, the video you mentioned even has a link to a pastebin explaining what they did to change/manipulate it in to doing that.

[@theSato]

It was edited by in-game actions (arbitrary code execution) beforehand, it is entirely possible to do without hacking the game or modding it with an outside source, and to do on console. :P And yeah, it was awesome! Easily one of the more impressive arbitrary code executions I've seen.

[@insightfulgarbage]

I remember finding a pokemon dupe glitch with my brother that involves trading and unplugging the link cable, but that ended up deleting one of our pokemons in the end 😅

[@llSuperSnivyll]

Using Trainer-Fly to get a pokémon that can trigger the Experience Underflow glitch is actually tremendously useful on the Virtual Console versions. Level 100 on the Medium-Slow experience group (which triggers the underflow) yields a Timid nature when transferred to Poké Bank. And a lot of special attackers (the Nidos, Gengar, Alakazam, Mew...) happen to be in that group, they get another benefit.

[@AudioGAWD]

I knew about the guy who taught you how to catch Pokémon but that led to me accidently finding out about pokemon from the safari zone being there on Cinnabar with the right set up.

[@junehanabi1756]

By the way, Brock through walls most likely sets 0xCD38 from 0 to 1 indicating scripted player movement which unsets after the script has run it's course or after some certain events like certain map changes. As long as 0xCD38 is active (Non-zero) all collision detection is disabled globally. You can manually trigger this in memory editing (For an emulator) by setting 0xCD38 to 1 and back to 0 when done or through gameshark by, I think, 0138CD01 if I translated that correctly but make sure to disable when done back to 0 (0138CD00) Since it's simply far too easy to walk into invalid areas immediately crashing the game.

Every time I try to remember how me and seemingly everyone other kid on the planet knew about the Missingno/item duplication glitch, I have no recollection of how it came to be. This was not only when we were like 5 years old, but also at a time when the internet was not necessarily a commonplace thing in the household. So I come to wonder how word of mouth started with the glitch that it became so well-known among the general population of kindergarten and early elementary school kids! It's interesting in that it's not like the other glitches meaning you could theoretically come across it by accident, but I feel like someone would have had to tell me to specifically talk to the old man and then surf the coast of Cinnabar.

[@Netbase2000]

The old man glitch and the zinnober glitch where the ones I used as a chield. I used my masterball before I knew the old man so I just had rare candys. My last Pokemon of all 150 Was tauros. I Catched him through the zinnober glitch. I'm surprised this wasn't a glitch everyone knows. In my friends circle everyone knew it.

[@arlenderkaloussian7560]

#6 isn't considered a glitch, and the reason why it occurs is not because Cinnabar Island is poorly programmed, but rather because the Pokemon encountered on the coast of Cinnabar is determined by the Pokemon available in the last area you were in (which is why MissingNo. is a thing). So it works with any place you can encounter Pokemon, rather than just the Safari Zone.

[@arlenderkaloussian7560]

When I said "which is why MissingNo. is a thing", I meant MissingNo. isn't a glitch. Because the name is replaced with "Old Man" rather than the name chosen for the player, it changes to encountering Pokemon depending on the player's name. Game Freak knew this, so programmed MissingNo. to make sure nothing crazy happens. Otherwise it would've been a glitchy mess. However, some people playing the game misinterpreted this, and thought it wasn't supposed to happen, and that it was a glitch, which isn't true. Because of this, you can choose a name that has to do with what you want to encounter while performing this glitch but not glitch. Choose different nicknames and see what you encounter! (you can also battle trainers by doing so, such as Professor Oak if you have the MN symbol in your name, but save before this, as the game can crash)

[@WIGutie]

Btw eastern shore of Seafoam islands can also be used in a similar fashion to the Safari Zone and Missingno tricks.

[@glitchedpokestudent911]

For the S.S. Anne glitch, you actually have to press right while next to the water and then Start immediately afterwards, save, and then reset. If you don't do this, your character will end up facing downwards instead, and the glitch wouldn't work.

Fun fact Jrose Nintendo Power was actually right when they said catching Missingno would crash your game. They just didn’t say it wouldn’t happen every time. Actually had my save data corrupt after catching one on my Red version when I was a kid. Friend of mine had his corrupt on Blue a few days after as well.

[@Terashi]

Holy crap. I think I accidentally hit on the Evolutionary Glitch as a kid. I remember beating Gary in the Lavender Tower fight and then my Pikachu immediately trying to evolve into something. I was freaked out but also super curious as to what it'd become. Unfortunately, I wasn't really ready for that Pikachu to evolve, so I canceled the evolution and it's been bugging me ever since as to what he'd evolve into. Guess it was Raichu all along. Huh.

[@SVoca]

My friend is a Pokemon fanatic (played every game with a full pokedex + 25 shinies) and she was confused when I brought up MissingNo. I showed her this vid and her mind was BLOWN. She even encountered MissingNo with the help of this vid.

[@HellHathNoFuryAtAll8]

I don’t recall stumbling upon any glitches on my own in gen 1. (I have exploited many after being told about them). I did, however, stumble upon the gen 4 Rage glitch without knowing about it and wondered how in the world my Ditto knew Rage, Defense Curl and Rollout after it had transformed into my Dunsparce and got caught several turns later. After trying and failing to replicate it, I looked it up, and I found out you have to exhaust the 5 PP from Rage while transformed in order for the moveset to be permanently copied. Fun side note: I used this to have something use Transform into something with Fly and Rage (and other moves), had Mr. Mime Copycat it to transform into it, used all Rage, and ended the battle with a Mr. Mime that can fly. I found it pretty funny.

[@iceg6621]

@@HellHathNoFuryAtAll8 Our glitches know no bounds

[@MelodicTurtleMetal]

@@HellHathNoFuryAtAll8 I stumbled upon the glitch people usually use to catch mew as a child. More out of panic due to being poisoned and realising I won't walk there - I walked in front of the trainer, paused, taught something dig, then escaped the fight to get to a pokemon center. 1hp, so still couldn't make it, so I used a rare candy to revive my starter, and just carried on with the game. Battled... I think a gambler? Then entered the grass to avoid another trainer and found a wild... Kabutops I think. As a child I tried convincing others you could catch one next to lavender town

[@HellHathNoFuryAtAll8]

MelodicTurtleMetal Probably just some haziness to the memory, but the glitch disables the start menu once you have dug away, so perhaps the rare candy was used prior to digging? Also, the encounter starts as soon as you re-enter the route, not when you enter the grass. Still, it’s cool that you stumbled upon it. It’s always crazy to have something so unexpected happen when you weren’t aware of the glitch.

[@MelodicTurtleMetal]

@@HellHathNoFuryAtAll8 I'm confident in not remembering it correctly. I do recall seeing the npc react to me when I flew away, which was amusing to me, and I remember poison being the reason I chose to try to avoid the trainer... But you're correct, I was trying to replicate the result last night and the menu doesn't open after teleporting, so the gambler must not have been involved. I loved finding oddities in games. It's strange how few I feel I stumbled across in pokemon gen 1 as a kid, considering how broken it seems to be.

[@red_again]

you forgot the exploding bulbasaur glitch in which idk how to do it but the outcome is all your pokemon in the party are replaced with 6 bulbasaurs that only know explosion as 3 of their moves with one other unspecified move that results in using explosion either way (this glitch is actually called the ZZAZZ glitch because the trainer is given the name ZZAZZ* to replace the previous trainer name) *I only put ZZAZZ because it is the short version of the actual name given to the trainer upon this glitch succeeding

[@younasdar5572]

5:26 The reason it does that is because computers don't actually have a value for the - character to put in front of the negative number, only 0 and 1, therefore if a number can be negative it is limited to 1 lower characters with a 1 in the unused spot signifiing the "negativeness". When adding and subtracting the computer still uses the same logic, no matter which type of number you use, so when you have +0 and subtract 1 it reads as -0, which cannot exist, and therefore it will assume the number was to high and set it to the maximum value. Tl;Dr: Because negative numbers aren't programmed in -1 will be the highest positive number, -2 the second highest etc. this is just the in depth explanation, in case anyone wanted it.

[@petedarock1521]

5:26 essentially what happens it it treats it like it subtracting 54 from 0 how ever its a counter so when it reaches the lowest programmed number it will reset to the highest number (look up the civ gandi glitch for a better explanation)

[@9bladesofice]

8:08 that specific glitch was eliminated though missingno (and a bunch of other glitch pokemon) weren't due to just using the mew glitch with a specific special stat from a ditto in the pokemon mansion to use your own special stat. It's incredibly tedious to use each time because the ditto is in the basement and it takes a little bit to get there but it is still possible. Missingnoxpert had a full let's glitch pokemon yellow series that covered a ton of glitches in pokemon yellow so I'd recommend checking out his channel. There's a lot of cool glitches in yellow and I hope to one day Get my own X - x because that seemed like the coolest pokemon since my favorite color is purple and it has a purple back sprite. Also glitch pokemon in that game are insane with stats and weight. But yeah it's amazing what you can do with glitches in those games but thankfully while there will be inevitably be glitches in every game it seems that later games have less glitches at least.

[@BlazeTheMovieFan]

Yeah, Pokémon Red/Blue have many great glitches for sure.

[@ang3r3dv3t]

That's crazy...I didn't know about the Cinnabar area duplication, I always talked to the old man, flew to Fushia City. Then surf down and to the left to Seafoam Island. And would surf up and down there for Missing No glitch etc.

[@niakisiakian6055]

I've said this 6 million times today (probably already commented on one of your videos... Whoops), but I had my Zubat use Supersonic, and then Bide. The enemy Pokémon damages itself or attacks you. The damage it does to itself adds to your bide, but you get no damage. It was pretty interesting. I thought it had something to do with the wild pokemon (ex. Zubat vs Zubat), but it works with two separate species, or at least with Zubat against something else

[@andrewhamop6665]

I remember my first glitch in Pokemon Blue, I was actually in a car and then I finally got to that precious spot on Cinnabar Island where your name data is stored on the side, I swam on the side of the island and found that precious precious Missingno I love Pokemon Red and Blue glitches!

[@ang3r3dv3t]

I always used the right side of Seafoam Islands for Missing No...didn't know you could use Cinnabar island lol.

[@HellHathNoFuryAtAll8]

setovegeta Your memory must be incorrect. Only the right side of Cinnabar island is incorrectly programmed as grass tiles. The reason you get encounters either related to your name or Safari Zone in the examples mentioned is that there are no grass encounters in Cinnabar’s encounter table, so the game looks for the most recent info in the grass encounter tables. Viridian and Fuschia both have no grass encounters, so after finishing the Old Man tutorial or leaving the Safari Zone, your name or the Safari Zone area you were last in (yes, the area within the Safari Zone matters regarding what you find) respectively will be the data it finds, but only if you go directly to Cinnabar without entering any routes that have grass encounters.

[@HellHathNoFuryAtAll8]

Actually, I’m wrong about your memory. You can do it on that coast. I never realized that, but it makes sense they would use the same type of tile there, and there are no grass encounters on the routes with Seafoam Islands, so I should have known. Sorry for my mistake.

Why teach it fly? ... Actually sounds a little familiar, did I do that?

[@thedepresseddonkey9675]

Brock through walls happens because the specific moves and PP for the moves writes code for the game and it tells you where it's taking you, the reason it softlocks if you do it wrong is because it doesn't know where your supposed to be going if you talk to the guy from the right, I think that's how it works anyway.

[@-_soy_-888]

Cool stuff Jrose

[@Aenir1992]

This video makes me remember, that I need to find a way, how to execute the glitch i found back in the old days. I found a way how to use missingno in pokemon yellow. When i was viewing his summary, sometimes the environment got messed up, like just "sunny town" or "glitch city". With that i was able to change the tiles where i could walk. In Pallett Town there is fields of grass next to Pallet town hidden behind the rocks, that you cant pass. So I was experimenting. But never got it to work there. But with a wallhack i found, there is no encounter at all or the regular Rattata and Pidgey. At that old times, i considered it possible, to encounter Mew there. But on my quest to getting Mew, i found, that the Wall in Fuchsia City gets also a pass, where you can access the endless sea that is next to Cinnabar and the route that connects Pallet Town with Cinnabar Island. Just when you are roughly about to reach Cinnabar Island, it may crash. That was how I figured out to use missingno actually useful and worked only in Pokemon Yellow, for some odd reason. Also sometimes viewing its Summary, it may replace the first Move of the leading Pokemon of your Party with Vine Whip. Was fun. Tried to teach Pikachu Surf with that method without the need to put an Effort into beating the Master Cup of Premium Cup Round 2 in Pokemon Stadium. Well then I got an Xploder and had all available Pokemon on and was just running into Grass and that was actual fun, because you never knew, what you actually caught. Because it added a random Pokedex entry and the Pokemon was completely different from what the entry was. But that was external Hardware then. But still I was shamefully proud on having hacked Mew into my Games. After they was traded, they was mostly Bug-free. But I can't say for sure. At that time using that kind of cheating devices was risky, as the games were already unstable things in itself. Was fun, when I had in Gold and Silver the Xploder Fun, to catch Celebi and that was the only code of hacking Pokemon into the wild, to make them catchable. But when I decided to delete that Savefile from Gold, where I used that from, I transfered all Items I cheated on there, into the Metalbox in Pokemon Stadium2. That was ok. But when I moved Pokemon into Boxes I had stored into Stadum2's Memory and wanted to save, it endlessly tried, without ending. Then I had no choice but to hard reset the N64. I expected my Gold Save File to begone, which wouldnt have mattered much, but it still was there. Gone was my 2 Boxes full of Pokemon in Stadium 2 Memory. Not the entire 12 Boxes but 2. That was how I decided to not use any cheating device, which is external Hardware. But using bugs in a game is fine with me.

Non-glitch way to get to the truck that I did as a kid, get hm01 then die to a trainer on the ship, you spawn at pokemon center with hm01 and the ship hasn't departed. Then come back later with surf.
