How I Made the Impossible Trade Between GEN2 and GEN3

The project I've been working on for a long time. Making a trade between GEN2 and GEN3. I will be making future videos where I'm going more into detail about the reverse engineering process for both generations.
In case you're wondering, it is possible to send over the GEN2 Pokémon to GEN4 using Pal Park!

Although I feel like the actual reason Ninty didn't make a transfer tool like that, having the actual source code to both the gen 2 and gen 3 games and all, would be the cost of manufacturing them at the time not being worth it given the potential customer base that would've been willing to buy it.

This means hypothetically you could bring MissingNo. On the trip of a lifetime, I’m sure he gets changed into another Pokémon as an error handler but it’s the thought that counts!

[@ThatVulcan]

It would be grand if one of the extremely glitchy pokemon from Gen 1 were thrown into Gen 2 and then so forth, utilizing the Johto Guard glitch to get them over. Technically the PokeStar Studios "actors" are also pokemon, so I'd love to see something with them as well, as they operate very similarly to other placeholder glitches in the series such as MissingNo, ??, and the satanic mess that is Gen 4's glitch pokemon. Showcase that double Watergun in Generation 8 lmfao

[@NefosG]

Since Missingno would have a Pokemon ID with a range of 1 byte (0~255), I'd assume he'd remain glitched only if he had ID 0, since 252~255 maps with the starters of gen 3.

[@socialistrepublicofvietnam1500]

Doesn't Gen-2 literally have a system to prevent glitch pokémon from being transfered over? Honestly, thank god because then Gen 2 would be caught up in Gen 1's mess

History was made here... Btw, my suggestion when it comes to the Nature is to make them based on the highest and lowest stat: for example, if the pokémon lowest stat is the Sp. Atk and highest is the Atk, then it should be an Adamant pokémon, so atleast the player who receives the pokémon benefits from it. Tho the Pokébanka had its own official way to apply a nature, I think depending on the last two digits of the exp... The ability maybe should random, so at least if you don't get the desirable ability, just trade back to the old games and then trade back to the newer ones for a new roll of the value.

[@Lucifronz]

It's not really that much of a game-changer, though. It would be *far* simpler to just get a VC copy and a tool to read your cartridge. Then you just put the save data there and, voila, completely valid and official copy of your Pokemon, complete with hidden ability and several perfect IVs to boot. I suppose if you really wanted to bring them from Generations 3 and onwards, this would be preferable, but I would never personally do this because the services are bound to put a limitation on that someday. Like how you can only have a Mew with very specific OTs transferred and so on. It's just one reason why when I started replaying all of the games more or less in order (on Ultra Moon right now), I made a point to only get Pokemon I could actually legitimately obtain some way, rather than hacking or editing Pokemon for fun, as I didn't want to get attached to something that I couldn't bring into the Switch games because of some technicality.

[@joemomma2218]

It wouldve been game changing, but unfortunately, it's 2022. Everyone who's first games were gens 1 and 2 have lost those pokemon long ago because of how the games were tied to the internal battery. If this was perfected and time travel was possible, you'd have a point.

The only thing i think that holds this thing back from being able to be used with standard folks (aside from it being a custom piece) is that the National Ribbon, while fitting, unfortunately makes it noticeable as an illegitimate Pokemon: only certain Pokemon from Colosseum and Gale of Darkness could earn the National Ribbon. This is an easy enough fix though: by giving the Pokemon the Effort Ribbon, which is normally given for maxing out EVs but EVs can be reset, and the ribbon is for "exceptionally hard workers", this would make the Pokemon legitimate when traded over to Pokemon Bank.

@@Zei33 there's nothing sad about it. There's also no such thing as physical data you can read without it being converted through some sort of programming language or in other words code. Most people here just don't understand how it works but the modules use conversion codes to change the data stored by inputs from one format to another. In a sense he's looking into the conversion code but really by just tweaking its settings. Granted I believe it's alot harder to edit data transfer protocols through physical components than virtual ones, what I'm saying is we don't have enough people in the community who actually study flash memory data to write those wiki articles like the mega nerds who did the work for him on these games (props to them) or in this case, him who bothered to use that code to his advantage and manage to tweak the transfer method. Through hardware which is especially impressive. However, seeing this video I was surprised no one had done it by now. Especially in emulators case.

[@tigerstar35]

You need to bring a Fissure machamp and give it No guard. This would be competitively game breaking

[@ZoofyZoof]

That doesn't work

[@Bruhcation]

@@ZoofyZoof actually it may be possible because from gen 3 you could transfer it until gen 6 where you can get a ability capsule to change the ability, but to transfer it all the way to gen 8 until pokemon bank shuts down, though it’s uncertain

[@ZoofyZoof]

@@Bruhcation No, I mean it's literally impossible, GameFreak thought of this. If Machamp has No Guard, it's not allowed to have Fissure on it. If it has Fissure, it's not allowed to have No Guard. You have to hack that in

[@Slimeonian]

@@ZoofyZoof with the device in this video it would be possible tho. Get a Machamp in Gen 1, teach it Fissure, trade it to gen 2, then trade it again to gen 3, where it will then gain an ability. Even if the Machamp gets Guts instead of No Guard, you could trade it to gen 4, then 5, then 6 and give it an ability capsule, then boom you have a No Guard Fissure Machamp. The only reason it’s not possible right now is cause any Pokémon from the virtual console that gets put into Pokémon Bank will always have their hidden abilities. But hidden abilities didn’t exist until Gen 5, so Machamp wouldn’t get it’s hidden ability if you traded it to Gen 3

[@estabravo]

@@Slimeonian weren’t hidden abilities introduced in gen 5 as dreamworld abilities or was that something else?

[@Voxridian]

This is an astounding development after 20 years! The fact you made a physical device to work the connection to make this possible with original games (not digitally emulated games) is amazing! I hope devices like these eventually become available to players

[@Anarkkie]

I would definitely purchase this if it were available. Amazing work.

[@spongebabe27]

Yeah this is absolutely insane, amazing work bro

[@briansilva3344]

This is beautiful! My brother and I originally bought Pokemon Colossum because we thought that was the key to connect the Gen 2 and 3 generation of games. We thought that because we saw the Johto pokemon in there and thought it had to be the case. We were wrong, but it still was a fun game.

[@mrfippi]

I was extremely excited to see this pop up on Hackaday! I've been working on the same project on my own and am half way through reverse engineering the Gen 3 protocol; i'm using an ESP32 with a custom-built hat. What are the chances you have your code available for us to look at? There's plenty I could learn from you. Well done regardless!!

[@Goppier]

@fippi Thanks! I'm not ready to release stuff like that at the moment. I plan to release documentation at some point, but I don't know when since my free time is limited. I wish you good luck on your project!

[@rubberduck2216]

If you ever decide to sell these I'm interested. Please and thank you

[@MattiaRaffaldi]

Please both of you don't keep this for yourself, open source these project and give them to the community, the world need this.

[@Goppier]

​ @Mattia Raffaldi At the moment this version is just very proof of concept and not something that's really worth selling or worth releasing all the code of of it at the moment. It's something I made pretty quickly in order to see if I was able to make it all work. I just want to work a bit more on it, do more testing and clean up the code overall before it's all ready to be sold or released in my eyes. I don't want to release something that is only half done.

[@rubberduck2216]

Hi it's me again do you guys have any updates on this. I'm still interested if you be willing to sell these please let Me know much appreciated.

[@burdanglarul]

Another amazing proyect, i've always wondered if it was possible to trade between gen 2 and 3, seeing it in realtime must've been a unique experience. Nicely done !

[@boks93]

That is actually insane dude! Huge congrats on this amazing project and how you managed to get it done. This could also be really helpful for any shiny hunters in the original 2nd Gen games to savely secure that their shinies will never just fade away on a dead battery. This comes from personal experience from me, because I found a shiny Pidgeotto, a shiny Kingler and a shiny Skarmory in my years and years of playing Pokémon Gold Version. They most probably don't exist anymore, but with your device I could have traded them to my Leaf Green and kept them forever. Crazy how this is possible!

[@lunareclipse2553]

Dude, this is so cool! As an aside, I've heard that the inability to trade between gen 2 and gen 3 games is a big reason that FireRed and LeafGreen were actually made, so that people would have a way to obtain Pokémon from previous generations that can't be found in Ruby Sapphire Emerald.

[@vard1865]

Is crazy how the lack of communication between Gen 2 and Gen 3 snowballed into 4 whole generations getting remakes

[@daniel_rossy_explica]

Yes but you have to 1) buy the 2 games, 2) recatch all the mons, 3) finish the games so you can catch the gen2 mons, and only then 4) trasfer everything to your gen3 games. It is way too much to do if you already had all the mons in your gen2 games.

[@onechristian1]

This is literally the coolest thing I've seen in ages, well done!

[@passbyicecube]

This will be one of my fav yt video, ever. Transfering gen1-2 pokemon to above 3 will always be something special that I wished I could do.

This is a love letter for all the kids that now are adults that losed every pokemon they captured in the 90´s and wanted to move them to gen 3 and when they found out they couldnt were depresed for a whole summer, great job really would love to have one of this module, hopefully some day that dream could be achieved, thanks for show us that this desire could be possible.

You can at least trade all the way up. Gen 1 and 2 interact easily enough, this tool to enable GBC to GBA communication, pal park to get to the DS era, various trade methods to get along to gen 5, 6, 7, and 8, then Pokemon Home to send the 'mon into the Gen 1 Virtual Console games.

@@valkyrasonara1797 It kills your Pokémon and simply puts a Pokémon with the same nickname and moves in its place. The IV are random but you will always have 3 perfect IVs because competitive killed Pokémon. I remember their is a video called pokebank kills your pokemon or something like that and its 100% true. Before G/S came out it randomized the gender like they couldn't even use the original attack IV for it.

You are such an incredible credit to the community, and your work always impresses. The way you outline and articulate information and thought process is equally impressive...and further begs the question, why this wasn't done sooner? I watched everything in this video and understood everything. I feel I could even reproduce the process described and create my own board given enough time. Did you study Computer Science, Electrical Engineering, or Computer Engineering at school? the sheer amount of tools and skills required to accomplish this spans numerous disciplines...Circuit Design, PCB design, Soldering (possibly even hot air) and wire splicing, signal and waveform analysis, Software Development, flashing silicon chips (embedded development), and core computer science principles. It's just a lot to take in...I hope your day job pays well.

[@sinnystyles6604]

Lots of interest, I think! I have personally been re-discovering my journeys by playing the original games in Japanese until I make it back up to current gen. Gen 2 was always my favorite and in my current Crystal playthrough on cart, I've had a bit of a story develop. Since I'm playing in Japanese and *painfully, slowly* learning some Hiragana & Katakana as I go, a lot of things can be confusing. I was doing the clone method to get all 3 starters, as anyone who wants to complete the Pokedex in these games does. However, I also wanted to color swap my trainer sprite. After finally attaining all 3 starters successfully, I realized I had set my clock to the wrong time. There is a button combination to reset this, which is also similar to deleting all save data. ....I deleted all of my progress, by mistake. So after that, I figured I would just soft reset until I got a trainer ID I liked and just keep that as my cool thing. It was Friday 13th, around 3am (honestly it probably was 3:13 am I really wouldn't be surprised) and I finally got one I liked! My ID is 33313. Pretty damn crazy considering the context. HOWEVER. I accidentally chose the male trainer. Guess Friday the 13th struck, after all. Anyway I'm now playing the game as normal and it's awesome. Chose to stick with it. I love Crystal so much. But now every single Pokemon I catch is so much more special to me. They all carry that insanely unique trainer ID on that fateful Friday the 13th. I am planning on transferring my 'mons to Pokemon Stadium 2 so I can preserve them but really, if something like your super cool device was available- I'd opt for that in a heartbeat. It'd mean so much and be such an impossible leap under normal circumstance that I'd probably pay for the device even with the fine print that says "this is a fan made 3rd party device that cannot be responsible for any lost stuff!" So yah. If you choose to read this, thank you! It honestly sounds like some messed up creepypasta but it's real. I was thinking about uploading a small video about it but I DO have pictures if you were curious! ^-^
