I'm honestly surprised this isn't shared already, but whatever. Quite the interesting ROM. The NUS-64 cartridge requires a special hardware called the NUS Checker. I have looked for information on this, but this is all I can find. This isn't on TCRF either. - DOWNLOAD - (this includes the rom, patched rom to run on emulators, and others!) Spoiler: Internal ROM Info (cred. eludevisibility) The .rar linked has three roms; NUS-64.sfc (original), test.sfc (unknown, possibly bad dump), and patched.sfc (patched so that it runs on emulators, more information in the rar.) This came from the file 'NUS-64.info' It has been modified for easier reading.

From eludevisibility.org (linkaroonie, you should definitely check it out. they have pictures on the page in which im going to be talking about below.); "The NUS software on the cart is designed to work ONLY on the special NUS Checker hardware system. While the physical flash cart can technically run on a standard SNES, the NUS test software programmed on it MUST be used in combination with the Checker hardware to use its functions. All those red Caution messages you see when booting the cart is errors where the program is trying to communicate with the special hardware and not receiving the responses it expects. Standard controllers aren’t supported by the software at all, further proof that it’s not meant for regular systems. All user input goes through a special register instead. Apparently, the NUS Checker hardware has its own kind of controller (or more likely, has buttons or a keypad located on the front panel) that must be used to navigate the menus. It’s possible to create fake input by using cheat codes to navigate through the menus. But there’s not much to explore or do as it’s not running on the correct system. As its name suggests, it just checks the hardware and vice versa and that’s about it" From what it sounds like, it was a developer system for the SFC, but I haven't seen any other documentation or pictures on it. Interestingly enough, the cartridge shows a picture of an N64 cartridge, and its even named NUS-64. Maybe a prototype N64? And would you look at that, a string of games in the SRAM, that are all for... the n64... Spoiler: Not even joking.

Thanks. EDIT: I have tried this on my sd2snes. Patched one gives an error, the other two dont run. When cheats come out for it, ill run it again but with the codes on the page that allow me to get past the menus. EDIT 1/11/17: Sorry for not adding this before. The cartridge has dip switches that allow to chose some SRAM configurations, and to change between LoROM and HiROM. Dont know why this is. Thanks to friends over at NintendoAge!
