Race Drivin' is considered an arcade classic in some quarters, which made its SNES port extremely disappointing back in 1992. Offering a meagre 4 frames-per-second, that edition was widely slated, but now, one software engineer has reverse-engineered it to run at a significantly enhanced 30fps.
This comes from Vitor Vilela, who previously undertook SNES rewrites for Super R-Type and Contra III, removing slowdown issues that affected those ports. By using this approach, Vitor's been able to improve Race Drivin' awful frame rate.
It's done through Nintendo's Super Accelerator 1 (SA1) enhancement chip, which offered faster clock speeds and more RAM. As such, this goes beyond your standard retroactive upgrades like, say, SNES ray tracing.
SA1 was only used in a select few SNES games across 1995-1997, such as Super Mario RPG: Legend of the Seven Stars and Kirby Super Star. Considering it arrived later in the SNES lifecycle, it's certainly interesting to see what benefits it can bring to earlier games.
The most exciting news is that Vitor is now working on increasing the frame rate for Star Fox:
