This is Top Gear 2, running on the SA-1 chip at 60 FPS!! The original game only runs at about 12-15 FPS! It stays on the same speed as original, but it's way more smoother, detailed and as a racing game you now feel a better control of car!

It works on real hardware and this is my first mod that uses FastROM and SA-1 at the same time, in parallel, effective 14 MHz. It's planned to be released once SimCity SA-1 and Super Metroid SA-1 are finished, but it's playable alright and 2-player mode will be at 60 FPS too.

Top Gear 2 in particular is one of my childhood games. I traded it with a Spiderman SNES game. I had a lot of fun playing on a old Mitsubishi TV which of course, had Stereo support so I was benefit from the incredible game's soundtrack. I'm very excited for this future SA-1 mod.

I thought that FastROM and SA-1 weren't compatible? Can you explain better how exactly they interact?

If SNES read ROM at FastROM speed the SA-1 CPU stays paused if it attempts to read ROM So either it needs to run at I-RAM or at most the SNES need to do other things to the SA-1 never get locked.
