It is posible to put 2 or more games on a CD

[Kendomon]

well yes and no, if you accomplished the task you'd need a game enhancer/Gold finger that can access the rom files and you'd start the game by clicking on the exe file.

Total waste of time, the games small enough aren't worth playing, both games would have to add up to 650/700 MB in order to fit on a cdr.
