IPL demo

This program targets an IPL present in FDS games developed by Namco. Once loaded, a CRC32 checksum of the $0200~$07FF region occupied by the IPL will be calculated and displayed. The checksum for the IPL extracted from Pac-Man (FDS) is D908C459.

Usage

On Mesen2, the compiled IPL-demo.hex file must be loaded using the Lua script from IPL-MAIN. Once a replica of the Namco IPL Interface hardware has been made, it should then become possible to load this program on original hardware.

Building

Required tools:

• CC65 toolchain: https://cc65.github.io/
• Python IntelHex library: https://github.com/python-intelhex/intelhex

A simple make should then work.
