Pokemon Gold (1997 Demo) - Escaping the Demo Bounds

The Spaceworld prototype is interesting and all, but we're restricted pretty heavily by the demo barriers. So let's glitch past them, using only the few tools we have access to within the demo!

[@brittanybasinger4163]

imagine somebody doing this at Spaceworld 1997 being all like "Cool, you made it easier to do arbitrary code execution!"

[@waterpig-p]

We need to raid Area 51 again and get the time machine

[@josemartinriosr.6534]

Fun fact at 7:16, Skarmory's official Japanese name is エアームド Airmid, but in the demo it's named ヨロリドリ Yoroidori which means armored bird, and Skarmory is known as the Armored Bird Pokemon.

Arbitrary code execution? I WANT DEMO GOLD PONG EDITION!

[@vhscassette6583]

lmao at first i was like 'i forgot that the demos only in japanese so far. i wonder what the text says' n then as soon as it goes to shit its like 'LMAO NVM I GUESS'

[@MrCheeze]

For the record, it's loading the graphics for pokemon 00's menu sprite that corrupts the font. With a few extra switches, we could probably avoid the effect, but where's the fun in that?

[@vhscassette6583]

ooooh, interesting.. so like.. (im kind of a noob srry) the font got corrupted bc u switched the 2nd pokemon slot with the info from the 7th slot? :0

[@MrCheeze]

Yes, that's exactly it. As a side effect of moving the name around to where I want it, the species byte also happens to get changed to a species that had no valid menu sprite.

[@vhscassette6583]

ooo i get it! thats interesting. lmao man ive been interested in like, glitches/exploits in pokemon games for a long ass time but i never wouldve guessed that people can do such intricate stuff with a lot of tinkering around, especially something as 'new' as the g/s demos. this video was super interestin to watch btw, great job n thanks for explainin the font corruption! lmao

[@KelynFerguson]

I'd love to see someone turn this into a full game, considering a lot of the groundwork is already there and it's already different enough from Gold that it'd be cool to play through it.

[@henrythedumbfk1073]

There is a romhack named pokemon gold 97

[@TXFDA]

Welp, you have your wish. Pokemon Super Gold 97 is essentially just that. The Spaceworld demo but made fully playable. There's also Gold 97 Reforged that takes Super Gold and polishes it up into a full GBC game.

[@lamato7191]

God these are so entertaining to watch

[@llSuperSnivyll]

Pretty interesting that the select glitch exists in the demo, considering it is fixed in the most recent versions of the Gen I engine. Did they use an early build of that engine to make this?

[@s1revive398]

they use old engines in demos

[@llSuperSnivyll]

Sure, I understand that... but they already had a newer working engine - the one used in Red/Blue and Yellow. Instead, they seem to have picked the Red/Green engine.

[@plushifoxed]

pokemon 2 almost certainly split off in terms of development extremely early, likely right after red and green were done there would be no really good reason to keep up with all the little bug fixes and such in the gen 1 codebase considering that they might make large changes during development that would potentially nullify those bug fixes instead, they likely went ahead near the end of development and caught up with any fixes that were still necessary with the updated engine

[@mspeter97]

@@plushifoxed Same situation happened with Sonic 2. The spike glitch from Sonic 1 was fixed in the Jp revision of Sonic 1 released in July 1991, yet every sonic 2 proto up to Beta 5 from mid-september 1992 still retain that glitch.

[@TXFDA]

Man, imagine going back in time, visiting Spaceworld 97, and doing this at one of the demo kiosks? Though you'd probably have staff on you the first time anything even remotely glitchy happened. Or even funnier, bringing a copy of the demo on a flashcart with a real GBC, and just walking around the Pokemon area playing it. Even better, bring one of those rom hacks like Super Gold 97 or Gold 97 Reforged that turns the demo into a complete game. Blow everyone's mind.

[@Kivamusicchannel]

I really wish they made a completed modernized version of this game as spin off in an alternate dimension.

[@jhicks9902]

pokemon gold 97 reforged!

[@TXFDA]

@@jhicks9902 Or Super Gold 97 if you want something a little closer to the demo in terms of graphics and stuff. Super Gold is essentially an in-between of the Demo and Reforged.

Absolutely love these type of videos, thank you sincerely for them good Sir or Ma'am & btw I have a question if you don't mind me asking???? Any idea where to find Kotora the as I call if, thunder-cat? Route 102???? I have been trying to find it before I get to the next / second rival battle if possible.....

[@danielwgk]

Yas kween! Always killing it on these exploits. You never cease to amaze

[@deliaway7333]

Illogic. That's what this glich is made of.

[@francescocapacci9941]

I heard this game gas a new set of HM completely different, but I've never seen a video of their use outside battle. Wasn't implemented yet?

[@MrCheeze]

There's a new set of moves, that behave exactly the same as the gen 1 HMs. Most likely this was done to prevent trading up Pokemon with the moves from gen 1. Also, only three of them are implemented at this point in time. Uproot (Cut) - Implemented, and can be used without any badges. However the code was written before they changed the tileset format. As a result, the field move works ONLY on the grass outside the demo routes that acts like a solid wall. Also, it doesn't work on any trees, regardless of tileset. Wind Ride (Fly) - Implemented, and requires badge flag #3. Displays the map of Japan and allows access to any city, regardless of whether you've been there. Water Sport (Surf) - Implemented, and requires badge flag #5. Works completely normally. The rest had not been coded yet. The engine is more different from gen 1 than it looks, so reusing code for Strength/Flash wasn't really an option.

[@francescocapacci9941]

Thanks! So the statement that HM Bounce would have used to surpass the holes in the ground next to HighTech city is just hoax/speculation. It's fascinating that GameFreak would have taken this turn of having different HM sets for any generation. It 'd have given a chance to make better moves in-battle for underrated HM, like Strength. So people 'd have been less unhappy by HMs. I can immagine very different pokemon would have lean the "same" HM. Uproot would have been used by bulky pokemon like Machamp? Bright Moss by several Grass type, but not the same Electric one who can learn Flash. Water sport 'd have been prerogative of water pokemon, but would have excluded all those weird pokemon that can learn Surf in Gen I: Rydhon, etc. That's a lot of fun to think!

[@MrCheeze]

Bounce is water type, so it's a safe assumption that it serves the same purpose as Waterfall does in the final game. Maybe available to different Pokemon though.

[@francescocapacci9941]

You're right. On the other side, Bounce looks an unprogrammed move, likely Splash as placeholder. As far as I know, there aren't waterfalls in the overworld of demo. With the exception of the entrance of alpha/unknown ruins in Birdon. Someone states that's sand, not water. I dunno. So I guess it came the assumption the same Bounce could have worked with the strange holes in the ground. :D bye!

[@MrCheeze]

Feels like the move was designed with Magikarp in mind, given that it's famous both for 1) leaping up waterfalls and 2) doing no damage.

[@dryued6874]

Is that screen on the right a debug screen or something? It seems to be displaying garbage before you've even done anything.

[@georgeurban8970]

I believe it’s what the RAM would look like if it was visualized

[@renakunisaki]

It's showing the Pokemon data and names as tiles, so you can see the name move around.

[@MrCheeze]

It visualizes the binary data for Pokemon 1-6, as well as the out of bounds Pokemon #7 that actually corresponds to name data, as text. I realize this makes it a bit gibberish, but the only thing that really matters for our purposes is seeing how it swaps around.

[@dryued6874]

How is it visualized? Is it an emulator plugin or something?

[@FabioGnecco]

what's the difference between Demo, Proto and Beta ? because nowadays they named everything demo lol

[@Pawlok131]

Demo is a demonstration version: like the name says, it serves a purpose of demonstrating a product to audience. Prototype is a proof of concept: it serves as a blueprint for whole product, it might finish up as a complete product, or even be completely scrapped. Beta versions are most of the time products that are going to be a final version, only needing some adjustments, be it bugfixes, maybe addition of some new minor features etc.

[@girthbrooks1708]

Is anyone currently working on a playable cartridge version? That would be so cool

[@MrCheeze]

I think there was a project to translate and open things up a bit, but it stalled and is inactive at this point...

[@girthbrooks1708]

Damn, so unfortunate. Yeah I try to keep up with TCRF but the hype from a year ago has seemed to die down...might have to learn how to code this thing myself.

[@Finnyan]

But wasn't this already possible on debug mode? To explore the rest of the cities?

[@Finnyan]

But i gotta say, quite amazing that you found a way to do this in such a short area ^^ (and without debug mode)

[@MrCheeze]

Well, the debug ROM is a separate build of the game entirely - the one I'm using doesn't have any debug mode to turn on. And trying to break a game that comes with built-in cheat codes to begin with isn't nearly as interesting to me, so I stick strictly to this one. (Interestingly, due to the seemingly minor difference of Girafarig not carrying an Apple, the specific route shown here is NOT possible by playing on the debug ROM with debug mode turned off.)

[@Finnyan]

MrCheeze i see, and who doesn't like a good challenge :D wouldn't be as intresting video by exploring the outside area in debug as it is to break the game and doing something way more intresting and complex then that. You finding a way to break pokemon gold with only few routes is pretty impressing. ^^

[@shadedcycle]

Or you could find a debug version.... and press Select and press the second option in the debug menu

[@asra-5180]

That is boring and not fun. Are you also using guides to complete puzzle pictures?

Unfortunately glitch moves don't really help much at all in gen 2, including this game.
