Finally, I found something even more unusual than the Super Famicom Box.http://dforce3000.de/
has info (and video footage) about this Korean multicart containing 20 NES games. Interestingly it contains a custom sound driver and the games themselves have been hacked to include SNES sound effects and music, which I have dumped.
Unfortunately, the cartridge uses unusual NES-style bank switching (most likely as copy protection), meaning it doesn't work in emulators - the program expects everything to always be between banks 00-02, when this is rarely the case in the cartridge itself. I was able to do some hacking to get the menu itself working; I started working on fixing each of the individual games, but rewriting dozens upon dozens of JSL and JML instructions proved too tedious for one game, let alone all twenty of them. For practical purposes it'll probably have to wait until someone creates a custom emulator build that supports the bank switching scheme (write some value to $8000 that controls what part of the ROM is visible in addresses 008000 through 02FFFF, then jump to the reset address.)
Anyway, there are 23(?) SPCs in this set, presumably all based on the original music and jingles in the games included in the cart. The only one I've titled so far is the main menu music; I recognize a few of the others, like SMB1, Bomberman, and Galaga, but someone with more extensive knowledge of "first-gen" NES game music will have to tackle this one. I don't even know the full list of which 20 games are in the cart, since not all of the ROMs have the game's title in the header (the ones I can remember off the top of my head: SMB1, Spartan X (aka Kung Fu Master), Circus Troupe, Road Fighter, Bomberman, Galaga, Star Force, Pinball, Twinbee, possibly Arkanoid (based on graphics I found in the ROM...)
