My first attempt into "look and analyze" type of videos. Hope you enjoy.

For ROM test in Codemasters NES game, to trigger its checksum, hold Up + Down + Left + Right + A + Select + Start, then press Reset. For RAM test, press and hold down same combination, only with B button instead of A, then press Reset as well. I may have to note that it may not always work with keyboards on emulators, so you have to use gamepad for this checksum to work properly. As for consoles, you have to dig up a third-party controller, just in case.

Music: Toy Story (Sega Mega Drive) - Story Theme
