Will be updating if I find more glitch areas or possibly any undiscovered beta areas.
It would be good if there is one in Gold like the one in Crystal with the glitch trainer who can see diagonally.
Notable glitch locations:
To find one use 00 as the first value because all of these areas are not defined so there is a chance but small chance you will find one that doesn't do much, or try any large value or include 00 in the codes for example 0B,00 might work.
0A, 00: A lot of scrambled objects come onto the screen and then the game crashes with a white screen.
00, AA: Seems stable at first, you can see the player standing on grey tiles covered by orange things, but then the game switches to a white screen.
00, B1: Very interesting, the game is using a completely different 'glitch tileset' made of symbols, letters and plain coloured tiles. The game switches to a white screen.
80,80: Is the halfway point, thought it was likely this would work and did walked into some garbage like rock tiles etc but then the game turned to a black screen instead.
Important: Do not enter this location or it will corrupt your save file
18,2F: Similar to 0A, 00 lots of coloured scrambled objects and symbols come onto the screen, game crashes
There is a GSC glitch area already known which appears if you defeat one of the ??? glitches but not hex 00 Gold/Silver through the use of an emulator, the hex is unknown yet though
The G/S/C Glitch Dimension is not an actual glitch dimension it is just the game's attempt to reset the game failing to reload the colour palette correctly
