So ekeeke in 2011 or so made his emulator based on Charles's Mcdonalds's one non-free.
Why fork that emulator when we have MAME, Blastem or Mednafen as GPL alternative ?
Well... it's the only GPLv2 Megadrive emulator that can run Virtual Racing !
EDIT: Just realised notaz made his SVP code non-free... However, he does seem to be open to free his code ? i'll contact him
I also ported it to the RS-97 : It's kind of slow unfortunely at 528 Mhz but i made some improvements for that platform so i need to try that again.
It would be nice if someone could help with this :

There are more issues with the SDL backend that can be fixed easily thankfully.
