From Jlukas and the original thread:

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

General Info

The cartridge is 8 megabit (1,048,576 bytes) LoROM (without header, and all following addresses assume it’s not present)

Internal cart info starting at $007FC0 is almost completely blank except for required values (e.g., reset vector)

Address range $080000-0FFFFF is a mirror of $000000-07FFFF

Cassette is designed only to be used with NUS Checker

The program doesn’t recognize standard SNES controllers. User I/O is done through register $21C6

Patch Info

These address ranges are damaged (approximate):

$000980-00FFFF
$0305F0-0306FF
$0D9BA0-0DFFFF

The following individual bytes are not the same between mirrors:

Offset  - Value, Mirror - Notes
$0000A0 - $00,$80 - $80 is correct, used to jump to address $80C8
$017FFF - $28,$A8 - $A8 is probably correct, unused space area?
$026E22 - $B0,$F8 - $F8 is probably correct, unused space area?
$047D18 - $18,$9A - $9A is probably correct, unused space area?
$047D19 - $48,$EA - $EA is probably correct, unused space area?
$0F9D93 - $FA,$F8 - $FA is probably correct, unused space area?
$0F9F92 - $AB,$A9 - $AB is probably correct, unused space area?
$0F9F93 - $8A,$88 - $8A is probably correct, unused space area?

Patch Codes

Use these patch codes (Action Replay cheats) to skip past error messages and see the different menus.

When you see the Caution message on bootup, enter the following 3 patch codes and then use reset (ie, so the codes are active on bootup)

Patch code 008E1380 skips AD CONVERTER ERROR
Patch code 008E9780 skips NUS POWER-ON ERROR
Patch code 008EBB80 skips START SIGNAL ERROR

After applying these changes, instead of showing a Caution screen, the screen will be blank for several seconds before the program continues to load.

Next, a screen will appear “DATA SHEET CHECK”. This finishes after several seconds (usually with an error)

When the text EXIT appears on the bottom of the screen, enter patch code 00914600 to view the main menu.

As standard controllers are not supported, to access submenus you must enter one of the following patch code sets, and reset.

After the Data Sheet Check, the selected submenu will appear in place of the main menu.

0087B8xx
0087B9yy

F8A3 - Clear all data sheets in SHVC cassette
ADA5 - Cassette Check*

  • When screen is loaded, enter patch code 00A5F380 to proceed to the next screen (won’t work if error “Cannot check this cassette” is displayed).”

SRAM
TE16

There are 3 ROMs provided, one I was sent with the cart from eBay and another when I attempted to dump it, and one patched. The one from the auction seems more correct based on corrupted strings in my own. Not provided with the auction was the SRAM, which has more strings in it.
