Unfortunately currently there is no reliable way to port Pascal code to Web (it’s on the way, but alas, not there yet). And as I don’t own a MAC (and therefore no XCode) I can’t compile and test for MAC. So… not this jam :) However, maybe you could try running a Win32 version through Wine? AFAIR my games ran through Wine pretty well on Linux, but yeah, that needs to install Wine and I’m not sure if it’s worth just to try a few games.
