Tiny Cartridge

If you’d like to observe the recent (hell, let’s say ongoing) NES anniversary in a unique way, you can play some of the most interesting — and least functional in emulation — NES ROMS ever made: the test cartridges used by repair centers, originally housed in cool yellow plastic.

NES Player has downloadable ROMS of the Control Deck, Power Pad, controller, and other tester cartridges. Of course, since you’d likely be playing them in emulation, there’s no NES to test, making them interesting curiosities only.
