If youre confused getting through level 1, remember that you need something like 4 crystals and you also need to place platforms down while in 4 hot zones before the pillars will fall. Also, in general the finish line's box is really big so you just have to get near the floating ball thing.

rummaging through discord it looks like i either used this version of visual boy https://www.emuparadise.me/emulators/files/user/VisualBoyAdvance-1.8.0-511.exe or this one https://sourceforge.net/projects/vbam/files/latest/download

i havent touched this game in a long time or even used whatever the split program is, but if anyone is looking for an auto splitter for this game i wrote one for visual boy advance. If i remember correctly youll have to still split after killing the final bosses. i dont remember which of these files even do what but i think that i used the US rom. heres a link https://drive.google.com/drive/folders/1FBC0YjIX_vjTG1zMAi1865-Er-JM1aEx?usp=sharing
