well, the 1.2a Windows/SDL port has not been updated, only the emulation core is constantly updated, based on my work for the GC/Wii port
this still mean no joystick neither sound support, which isn't realy good for an emulator nowadays
even with the DOS port that I still use for debugging stuff, I never been able to get sound from my soundcard so it shouldn't really be useful
It would be nice if someone would add OpenGL and/or DirectX,Sound,Input support someday, with the current emulation core, i'm sure it would make a great (but certainly slower) opensource alternative to Kega and Regen
for the moment, this still makes Gens the best solution regarding
opensource emulator for PC platform... and it has 32x/CD support
Picodrive from notaz:
http://notaz.gp2x.de/pico.php#Win32 is also a very good alternative but I don't know if the last up-to-date sourcecode is available
