I've download MacSDLMESS and G5 binary of SDLMESS. My problem is I tried running the 7800 and it couldn't find the 7800 BIOS file. MacSDLMESS finds the ROMs in the ROM folder but apparently doesn't work with SDLMESS. I tried unziping it in the ROM folder and that doesn't work. Where I am I suppose put that BIOS file?
