Yes, I forgot to mention: I did try the compatibility trick, but it didn't work. Would've been too simple to be true. :P
Trying to come up with a solution, I realize the pc game is actually a port from a PC38 version. So I assumed if I found the original PX38 rom and played it with a PC38 emulator, it'd work.
It wasn't easy to find the rom, but it appears to be in this torrent:

Here's the problem, tho: there's about 280.000 files or more in that torrent, and there's no option to deselect them all when I try to launch it. Is there a way to deselect them all except Metal & Lace 2?
