Don't know if you follow arcade emulation like me, but anyways...
If you don't know, SEGA MODEL 1 BOARD, was a kinda of Prototype. It was initially planned just for tests. But Virtua Racing was such a sucess internally they decided to release it. It was very expensive since it was a project with the help of General Electric Aerospace ( Read NASA Simulators)
Anyway, the games on that board are very hard to emulate because lack of documents and info on it. The games were:
- Virtua Racing
- Star Wars Arcade
- Virtua Fighter
- Wing War
Wasn't i surprise when i saw the following link
Hope you like it.
