The authors originally wrote the game for Linux and Windows and require a system with better specifications than an AmigaOne to get it to run properly. Since ACK hasn't delivered on the dual-core high-end model Amigas to run AmigaOS 4, the project had been cancelled by Proost Software who was porting the game to the AmigaOne.
If you have a PC then just download racer from the link in a previous post. It is identical to the OS4 version and is available for freeware on Linux and Windows.
