whats a dma issue?

DMA "Direct Memory Access" is how the mega drive uploads Sonic's graphics to VRAM, there's a really annoying issue that can show up where if a DMA transferrer crosses a 128KiB ROM boundary, things can get a little corrupted, this is an actual hardware issue, so there isn't a true fix you just have to get around it, best way i can think of is to move sonic's art to another spot in the rom

Find ArtUnc_Sonic: BINCLUDE "art/uncompressed/Sonic's art.bin" and move it to somewhere else in the rom
