This was the first version of a test program that was used on SNES consoles to test them before sending them to vendors.
Here is some more info, copied from the description on Internet Archive:
"The following software was used within Nintendo’s Uji factory during the manufacturing of the Super Famicom. It appears to be the first version of the Aging software to be developed for the system, and has quite a few differences within the fonts and graphics shown when compared to later versions.
Surprisingly, this specific cartridge was recovered from Brazil. In 2003, Gradiente/Playtronic ceased to be Nintendo’s representative in the region, due to this, many accessories, games, repair parts, and internal equipment were sold to nearby stores. Notably, this is the first known instance of a prototype revision for a retail PCB (as noted by the “X1” on the PCB). It is also the first SNES test cartridge to be found which uses a Mask ROM instead of an EPROM to hold data."
Attached is a screenshot of the program and a photo of the cartridge. Here is a link to the ROM for those who would like to try it for themselves:
