c64-game-source-code's Introduction

Commodore C64 Game Source Code

Purpose

Start with an old Commodore C64 game disk which is as close to the original as possible (g64 or nib).
Include the copy protection.
Produce a commented assembler listing which reassembles to an exact copy of the originaL binary.
Make the source as variable as possible to allow any kind of modifications, data area and code relocation.
Sometimes add some own ideas to the game soures code for fun and as a proof of concept.
Sometimes add a (simple) level editor.
