A collection of test roms, hacked to execute specific invalid opcodes to indicate pass/fail

Shish's Hacked Versions of Various Test Roms

• blargg's test roms are great but hard to automate
• mooneye's test roms use LD B,B (opcode 0x40) to signal completion, but that's a valid instruction, which blargg's roms test, so that isn't ideal either

So I basically want to use those test suites, except tweaked to use an invalid opcode to indicate status. Specifically, I'm defining two new non-standard opcodes:

• 0xFC - exit with success
• 0xFD - exit with failure

and then hacking other people's test suites to use those.

This repo is primarily designed to be used for testing RosettaBoy (A collection of gameboy emulators written in a variety of languages) - but if anybody else thinks that this is a good idea you're welcome to use it. Also if anyone has any better ideas for how to do fully-automated test suites, I'm open to suggestions :)

Layout is <test suite name>/<test name>.gb
