150-in-1 (With CHR/PRG Test, NES)

150-in-1 is yet another NES multicart with repeated games. There's thousands of carts like this one.

ROM/PCB Test


An internal selftest program can be accessed by pressing Select + Start on the main menu. It performs a test of the CHR data, PRG data, mirroring support and banking support. It is similar to the ROM/PCB test in 200-in-1: Elfland with only the game's name changed and a different palette used on this screen. They most likely share the same multicart engine.
