Don’t ask, it simply happened and why shouldn’t it, every game should be preserved for future generations to…enjoy.
Anyway, via the MAME core, Tiger Game.Com works. There are some graphical glitches and sound is not perfect, but having played one of these when they came out due to an unfortunate friend of mine who today probably hates his parents, the experience is pretty close to how I remember it. Sluggish, slow, and clunky.
First up, set up your roms like this, with bios zipped up in the parent folder
Then, make sure you got these bios in the system/mame folder as well.
Now, you’ll be ready to run Game.Com games like a true champion. Just load your mame core and have at it.
