Add some tests #19

Open AndreaOrru opened 7 years ago

AndreaOrru commented 7 years ago

At least check if it compiles correctly.

I would be super interested in tiny unit tests for each mapper. They'd have to be 6502, and the unit test suite would load each up. Then they would run their tests, and write the result to a special memory address to let the test suite know.

Does this even make sense?

AndreaOrru commented 7 years ago

Yes it does. Good stuff.

I found a fairly exhaustive set of tests called "Holy Diver Batman" It covers SxROM (1), UxROM (2), TxROM (4), AxROM (7), PNROM (9), FxROM (10), INL-ROM Action 53 (28), BNROM (34), NROM/CNROM/GNROM (66), JxROM (69), IF-12 (78.3), TxSROM (118), UxROM (180)

Note: seems MMC1 and MMC3 fails the holy diver tests
