Top Gear SA-1 will still take a while to launch. It's not a trivial game, even if SA-1 is only called for road and object terrain generation, which in theory is an easier conversion compared to Super Metroid SA-1. Some of the car and object interaction routine still need to be moved to SA-1 regs.

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!

There is a lot of object<->object interaction that works by using PPU and CPU multipliers and an inverse table that assumes that the S-CPU registers are being used. These are being written to work with SA-1 directly.
