Diagnostics BIOS

A homebrew BIOS used to test various parts of cartridge systems. It includes improved/fixed versions of the tests found in the SNK BIOS along with many new ones to help indentify faults faster. A Z80 ROM, which is meant to be used in place of a game M1 ROM, can optionally be used to test the digital part of the sound system.
