This repository contains the fully annotated disassembly of the original King's Valley game, released by Konami for MSX in 1985 with code RC727. I hope you will find the code comments useful to understand how the game works.

Use Sjasm 0.39 or a compatible assembler:

sjasm kvalley.asm kvalley.rom

It is possible to build both versions by setting the VERSION2 constant to 1 or 0 in the kvalley.asm file. Version 2 fixes few bugs from the first version.

This repository is provided "as is" for education purposes only. Any non-educational use of this repository might be illegal if you do not own an original copy of the game.

Also, the repository will be removed if Konami or their legal representatives ask me to do so.
