There's the original interpreter, Sarien and Nagi to run AGI games under every Windows version (dunno 'bout Win 2000 though. It seems to even give problems with simple C++-programs, so...), the original interpreter can be used to run the games under DOS, but what should be used to run these games under 1) Mac, 2) Linux, 3) Win 2000?
Hope this's clearer.
