In 2012, the game's developer, Javier Arevalo Baeza, released the C source code (minus some commercial libraries) as public-domain software on GitHub. Later in 2025, a shareware version of "Speed Haste/Circuit Racer" for the Commodore Amiga, was developed by BSzili. Speed Haste is a 3D arcade racing game with 2 types of vehicles, and different cars per type: the famous F-1 and the Stock Cars (best known as Formula NASCAR), each with different characteristics and maneuverability. The player can compete in the championship mode, covering all circuits with an increasing difficulty, but identical for both car types. The multiplayer mode offers split-screen racing or IPX-based sessions with up to 4 players.
