NES/Famicom Gameplay - F1 Race

This is a fun little game which would have been better if Nintendo bothered to finish it! The last track just loops endlessly so I could only play up to track 5. There is a hack of the game here    • F-1 Race [hack] (All tracks, Turbo button ...   Here is part of the readme.txt file for the hack: What this hack does is enables the game to play through ALL 10 circuits of the game, and advancing the skill level every time the 10th circuit is completed. So, starting on skill level 1, Circuit 11 would actually be Circuit 1, but at skill level 2. And the circuit number displays correctly (Instead of "Circuit No.A" you get "Circuit No.10").
