I used duckstation emulator. and i used own cheatcodes and mappings to different buttons. to enhance the game with new audio and cameras. The Autopilot is driving , and i can step in and take over the driving at anytime. Orginally you can only watch the 3 lap replay, and here you can watch the full 60 lap race, live when the main race running, because the AI car only register lap times and don't use much memory for storing data, comparing to drivig yourself. This great NSX Turbo was only in the Jap version and it also had the best gamemusic. The cars are a bit dirty on the paint since the video clip is from the mid race. (shiny paint at the beginning gets dirty during long races).
BTW. The Toyota GT four was the goat in the jap version and was way faster than the other cars. It was tuned down the hp for the pal and US version. Sometimes the cpu audio can hang/stuck in the tiny buffer memory, so clearing/reset it can be done with pause button or switching to back with camera to the car who made that sound.
