The Snake game in Pokemon Silver (arbitrary code execution)
646Update! You can see the snake game being programmed in an actual Pokemon Crystal cartridge (with different ACE exploits) in this video - https://www.youtube.com/watch?v=g2mCyh7Y2xM
********************************************************************************************************************************************
Arbitrary code execution with Coin Case (explained by Sanqui, who discovered the ACE exploit): http://forums.glitchcity.info/index.php?topic=6716.0
Two different coin case setups are required. The first one to write our program in multiple iterations and the second one to make the game jump to it.
Setup 1 item list / asm code: http://pastebin.com/RG5HE9Ks (there is an error in this one. It says I38 = 01, but should be I38 = Max Potion [11], although Master Ball [01] also works)
Setup 2 item list / asm code: http://pastebin.com/X2hAyN9t
Box name characters to hex conversion: http://pastebin.com/4ZDpQXGe
Program asm code: http://pastebin.com/t8Qu6Pc2
Raw bytes: http://pastebin.com/72vbixu4
Pokemon Silver save file (the program is already written and the items in the PC correspond to the second setup, so you only need to use Coin Case once): http://www.mediafire.com/download/gf29w70lh2jpoio/Pokemon_Silver.sav
Check out this video by TheZZAZZGlitch where I took the idea from: https://www.youtube.com/watch?v=D3EvpRHL_vk (nevermind, you've already seen it).
The Coin Case Glitch is a translation error that is only present in the english localizations of Pokemon Gold and Pokemon Silver. That means, it won't work in Pokemon Crystal, or in Pokemon Gold or Silver in any other language. As for emulators, it won't work on VBA (as it doesn't emulate Echo RAM correctly), but will work fine in BGB or TGB.
Everything else is explained in the video.
