100-in-1 (Unchained Melody, NES)

100-in-1 is just your average NES multicart with even more repeated games.

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 pretty obvious that this multicart is a hack of 83-in-1 because the hackers didn't even change the text on this screen to say 100-in-1, and PRG/CHR checksums are untouched too, causing this test to fail.

Unused Graphics


The 83 from the intro of 83-in-1 exists in the rom, despite it having been changed for 100-in-1.
