What is it for?
Prototype
I think this means games that are playable but never been released (mostly for old gaming platforms). Can be found now on ROMs / ISOs versions but not on cartridges / CDs. For example, [[gameid:154499 Command & Conquer]] or [[gameid:10240 Sonic and Crackers]] for the Megadrvie.
Exactly.
Old Atari platforms had many of them.

[[quote:but not on cartridges]]
Well, not on commercially released cartridges (fancy label, no exposed chips). Most prototype ROMs originally came from a prototype cartridge. Once in a while a development version of a game designed for cartirdge is found on some other media. Such is the case with [[gameid:159353 Pit Fighter]].
