cashcow runs under windows only, and there will never be a dos version, since dos belongs in a museum ;) these new exes will also run under NT or 2000 i have absolutely no clue how much mem it needs, but i think 32megs should be more than enough. this thing was coded on a p2-450 with 128 megs and a tnt2, and it runs fine on that (doh), it also ran smooth at a p2-400 with a tnt, and i haven't been able to test it on anything slower, except for a p90 with 96megs and a dx2/75 laptop with 16megs and a 640x480x256 res, and yes, it actually worked on those two ;) i think it should run pretty well on anything above 300mhz. this slowness is of course not my own fault, but windows' =) oh, it probably won't run under NT.. sorry for that, but i dont have an NT machine available, i will install it soon tho, and if enough people (1 or more hehe) ask for an NT version, i will fire up the debugger and find the fuckin bug!
