This may be a YouTube video demonstrating a hypothetical Famicom expansion audio chip that combines the concept of an MP3 player on a Famicom cart with the "Write a number to a port to play a sound" interface of the Moero!! Pro Yakyuu sound chip. This wasn't viable with the high costs of memory in the NES era, but two decades later, NAND flash and transform audio decoding ASICs appear to have become cheap enough to include on a cartridge. In fact, someone's working on a project like this for the Super NES.
Each scene would show a playthrough with 12 to 20 seconds of the game music, followed by a similar playthrough with the music replaced by a non-chiptune version of the same song, used under fair use.
Before the video, the viewer sees a notice:
NOTICE: This video includes music from copyrighted video games and similar-sounding copyrighted sound recordings, as a comment on such similarity and on how mapper hardware together with said music could improve these games. The author of this video claims that this use is a fair use under U.S. copyright law.
These games have a menu option to play only sound effects:
|Jurassic Park||Level 1||Press Play on Tape - Comic Bakery|
|Klax||Bugsuk - Caverns of Cthulu||Bobby Prince - At Doom's Gate|
|Tetяis: The Soviet Mind Game||KARINKA||Russia2000 - Kalinka Dance Song|
|Tetris||Music 1||Dance of the Sugar-Plum Fairy|
|Dr. Mario||Fever||The Beatles - Lady Madonna|
|Pipe Dream||Music 1||Muse - Knights of Cydonia|
|Top Gun (U)||Attract mode (compared to actual gameplay that has no music)||Kenny Loggins - Danger Zone|
Games needing a patch
Some games need to be patched, whether through byte changes to the ROM or a Game Genie code, to get music not to play. (This Java applet translates single-byte patches to Game Genie codes so that they can be used with a PowerPak.) Please add only verified working no-music patches that keep the sound effects.
|Game||Replacement song||Patch to silence music|
