Endless - A dive into a C64 game

Read Original

The article details the author's process of reverse engineering the 1985 C64 game 'Endless' to understand how its large map was stored within the system's 64KB memory limit. Using a C64 debugger and 6502 assembly, they analyze the game's use of 8-character blocks, pointer-based compression, and memory addressing for both graphics and color data, explaining the technical challenges of working with the 8-bit architecture.
