Exhaust Heat II: F-1 Driver no Kiseki

Exhaust Heat II: F-1 Driver no Kiseki (エキゾースト・ヒート F1ドライバーへの軌跡) is an F1 racing game developed and published by SETA, released for the Super Famicom on March 5th, 1993. It is a sequel to early Super Famicom racing game, Exhaust Heat. It included a special chip called the ST010 to control AI behavior.

Development
During development, special attention was put into the feeling of grip during the race. The game was likely influenced by F-Zero and particularly the recently released Mario Kart.

ST010
Exhaust Heat II used a DSP chip called the ST010. This chip is actually an NEC uPD96050. This chip is used to handle AI cars in races. This can be seen in-game, where cars become more aggressive as you try to pass them. Exhaust Heat II is the only game this chip is used in.
