Would you be able to port bosconian?
and another question, is there a way to compile multiple games into one? So it could work like an old school namco museum compilation?
It is not impossible, although the Galaga hardware that Bosconian runs on has a triple CPU setup that might prove more tricky than Galaxians single Z80. Compiling multiple games into one shouldn't be a problem, if it's done the same way as e.g. '6-Pak' where there is a boot menu and you have to reset to get back to it.
