    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!)

    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...

    Does anyone have any information on this SFC/N64 frankenstein? 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!

    This is indeed the kind of rom you can share here.
    Real nifty BTW.

    So, if I read this correctly...there is a SNES based machine that runs this code to checksum retail N64 carts? Who / why would need that?

    Yep. Its just mysterious, is all. Theres no information of it out there except for the release of NUS-64. Besides, why would Nintendo checksum N64 software on SFC hardware?
    and also this fourm is for the rare and obscure sooo

    Maybe it's part of a game copier style device that uses SNES hardware to feed roms to an N64 used in early developing.

    Because SFC hardware was readily available at the time of early N64 development? It seems quite plausible that Nintendo would build a utility machine like this out of whatever technology they already had, and I'm sure they had SFC hardware and competent SFC developers on staff. Essentially, you build the next generation of tools out of the tools you currently have.

    My question is...what is the primary purpose of this machine? I initially thought of it as a dev cart copier like @sanni , but then again it's called a "checker". While the "EEPROM Copy" option #5 on the menu may make some think it might be a full cart copier, I think this is only referring to the EEPROM save chip as some N64 carts have instead of Battery+SRAM.

    My question is more about how did such a checksum verification + save game distribution machine work into the development workflow. I'm not questioning it's value as a utility, but rather trying to understand why someone would have built a standalone machine for functions that could be done on a standard devkit.

    Assuming it's like the Famicom and SFC cart checkers then it's got nothing to do with development. They were used as part of the IQC process to verify that newly assembled cartridges were operating correctly and also by the service department to check carts that were returned by customers. The machine was just a rather boring looking box with 2 cart slots and a little control panel. The test cart (which is what I assume this is dumped from) went into the top slot and the cart you wanted to verify went into the lower one.

    My guess is that they took the hardware and software they had already designed for the SFC cart checker and modified it to verify N64 carts. Most of it would be the same anyway, just the interfaces to the cartridge would need to be re engineered.

    I have nothing useful to add to this conversation. Just wanted to mention that from previous menu where you see the title of this thread, due to your avatar being the generic "A"...

    It makes it look like the thread title is "ANUS checker hardware".
