I tried to compile nsx2 0.04 using some compiler:
-vc6, I have to change all define, too difficult
-djgpp, but SDL for djgpp is not available
-mingw, but it has some errors while linking
If you want a copy of the one I did to work with the PCSX2 GS plugins to put on your web site I can send you the files source + executable. It gets between 42-43 fps on cubemastah.elf with the gstaris.dll plugin.
