Milk Race (MSX)

A cycling game that serves as a promotional tie-in to the 1987 Milk Race event.

Uncompiled Code#

Loaded at various code addresses are leftover bits of the game's code. The first two snippets are written in 6502 assembly language while the others are written in Z80 assembly language. The CPU used in MSX computers is a Z80, so it's odd that there would be any code written for a 6502.
