So, I've already made a TAS of Winx Club on the GBA, but there's one thing that needs to be looked into. When you hit a boss from OoB before starting the fight, the game freaks out. It'd be easier to show you: Link to video As you can see, things get messed up pretty quick. Getting hit, touching the boss, or attacking it will all have similar but different effects. After that, different movements will cause different effects as well. It seems that getting the boss back on screen causes even more issues, typically causing a quick crash. I lack the experience to debug this myself, although I have tried a bit. It seems that as soon as you interact with the boss, the beginning of the OAM gets messed up and is written to instead of some later section. I'd really love to see this lead to some skip, as it seems so promising. This can be done on any boss afaik. It can also be done on the first boss, you just need to hit it with a fireball from underneath and get it off screen as soon as possible. It's located in the top left corner of the screen, you can use my TAS as inputs to get out of bounds

Seems legit.

Yeah, hitting the top left corner in any boss screen (or the boss itself early in this case) can cause a game crash or some seriously funky effects to occur. With "double maps" glitch, you can transport a boss arena somewhere else and cause slightly different effects to happen as well (like the Troll in upstairs of Alfea). I've also seen big corruption once while testing the glitch of turbo talking to characters. On one occasion all graphics went nuts, a bit like in this example. EDIT: Here is the movie. Played on VBA v24. The glitch starts at the end of the movie file.

This game is seriously broken. Repeatedly opening and closing the pause menu crashes the game. Heck, sometimes the game randomly crashes on transitions. I figure this could be a goldmine for anyone who knows what to look for.
