blarggs-test-roms VS mooneye-test-suite

For actual documentation, you probably know the pandocs, but there are a lot of more specific information in the docs linked in their references, especially the cycle-accurate GB docs, the GB complete technical reference by Gekkio. You can also check the source code of the relevant test roms, like the Blargg’s test roms for more general behaviour and the MooneyeGB test suite for more specific things.

The thing about the Game Boy (or most consoles, really, but especially the Game Boy since it uses a custom CPU) is that we don't know all the details. People have had to reverse engineer it to figure stuff out. /u/gekkio is one of the people doing that work, and his technical reference and test suite are the (ongoing) results of that.

I tested it with the classic dmg-acid2 test rom and another rom called sprite_priority.gb which is part of the Mooneye Test Suite.

I am working on my Game Boy emulator and I'm trying to get the timer to work with mooneyes acceptance tests. Take this one as an example.

The mooneye-gb test suite has very specific tests for the timer (maybe too precise, they require emulating every little detail — but if you want that kind of accuracy, way to go)
