Stunt Car Racer (1989): Scientific Brad reverses Stunt Car Racer (Amiga) using Ghidra and Gemini

Scientific Brad is reverse engineering the 1989 Amiga game Stunt Car Racer, decompiling 480 functions with Ghidra after the REA tool failed on the m68k architecture, and is now using Gemini to assist with further analysis. The target binary lacks AmigaDOS, uses an RNC raw-MFM loader, and contains XOR-$80 obfuscated code, checksums and a suspicious 68000 TRACE vector; the Ghidra decompilation allowed mapping of the game's fixed-point suspension and physics systems.

The project uses Ghidra to decompile 480 functions and Gemini to assist with analysis after encountering limitations with the REA tool. Scientific Brad is performing reverse engineering on the 1989 Amiga game Stunt Car Racer. The target lacks AmigaDOS and utilizes an RNC raw-MFM loader. The binary contains XOR-$80 obfuscated code, checksums, and a suspicious 68000 TRACE vector. The author reports that the REA tool failed to process the m68k architecture, hitting a wall during analysis. Using Ghidra, the author decompiled 480 functions, which allowed for the mapping of the game's fixed-point suspension and physics systems. The author is currently using Gemini to assist with further analysis of the codebase.
