Revision as of 21:01, 14 October 2016


A test ROM is a program designed specifically to test whether the platform that the program is running on is working correctly. A test ROM can be used to test the accuracy of an emulator, as well as compare the behavior of different hardware revisions.

Blargg's tests

Blargg's tests are available at:

All tests were executed in each emulator's DMG mode, except the CGB sound test, which was executed in both DMG and CGB modes.

Real hardware (using a GB flash card)

Side note for the 3DS VC : it seemingly ran the ROMs in GBC mode, although I cannot confirm this is true. Tests will be conducted using other base ROMs for CIA injection that should enforce DMG mode.
