Fixed. But seriously, this is one of the most impressive things I've seen someone do with a Game Boy, nevermind that all of this is possible on an actual physical Game Boy (And GBA possibly)
I'm probably going to get obliterated for this, but is this really a "glitch?" The entire process stems from voluntary savedata corruption. That would be analogous to opening a Gens savestate in a hex editor, changing a bunch of values, then calling it a "glitch" when the game doesn't play right. I'm not in any way diminishing how incredibly fucking awesome this is, but it bothers me in the same way as when people glorify debug mode dickery as "look at this bug I found." There are numerous legitimate glitches in gen 1 (missingno, infinite items, find any Pokemon anywhere), but I think this one falls under a slightly different category. I mean, the game demands you to NOT TURN IT OFF WHILE SAVING.
