Megatech games are identical to their Genesis/SMS equivalents, however the Megatech cartridges contain a BIOS rom with the game instructions. In Megatech games your coins buy you time to play the game, how you perform in the game does not matter, you can die and start a new game providing you still have time, likewise you can be playing well and run out of time if you fail to insert more coins. This is the same method Nintendo used with their Playchoice 10 system.
