What is AccuracyCoin?
AccuracyCoin is a large collection of NES accuracy tests on a single NROM cartridge.
This ROM was designed for an NTSC console with an RP2A03G CPU and RP2C02G PPU. Some tests might fail on hardware with a different revision.
This ROM currently has 129 tests. These tests print “PASS” or “FAIL” on screen, and in the event of a failure, this ROM also provides an error code. In addition to those tests, this ROM also has 5 tests labeled “DRAW”, which don’t actually test for anything; rather, they simply print information on screen.
