I'm seeing QuickDraw PICT files, the make files seems to use Classic Mac-style file paths (Disk:Directory:File), and there's even an AppleScript in there referencing DeBabelizer 1.6 (who else remembers THAT app?)
edit: looks like the official 3DO development kit was Mac-based, and there was even a NuBus card with 3DO hardware on it for debugging
