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 almost identical to the ROM/PCB test in 200-in-1: Elfland with only the palette and multicart's name changed. Both carts likely share similar menu code.
