In the meantime, it appears that there was a spawn game for the SNES (so an emulator will work). You can see the game here:

Edit: And here's the ROM

Edit2: **** it, here's an emulator to play the ROM

Password is: The password for the ROM is "www.romguy.com" (remove the quotes)
Download MorphGear, and then the SNES Module above
You can also use Pocket SNES (get the release before .200 for it to see your ROMS) or SNES9xJ4u (Edit: Download Below). There's a couple other's out there for Gizmondo that may work for Mogul or other, but Morphgear is fine.

I know DASH and everyone already knows this, but hey, someone may not :)
