GBA Info

Super Mario Advance 3: Yoshi's Island is the port of Yoshi's Island to the GBA. It's a very faithful port but it does have some differences like minor level changes, new sound effects, and unfortunately, a smaller screen.

Most importantly due to it being a new system, there are differences in how some glitches that corrupt memory work especially OAM overflow and Out-Of-Bounds wrong warps. This leads to GBA having unique speedruns that may be interesting.

Note that this is under investigation and information may change and this is still not fully understood

Goal OAM Overflow Corruption (unlocking new levels)

TODO

Explain, link some pablo stuff

Wrong Warps differences

TODO

GBA doesn't clear previous screen exits from levels you visited so 1-1 warping can bring you there. Out-of-bounds warps read into VRAM table so it can be manipulated into many places
