The cart doesn't do much. It merely changes the machine ID code in the BIOS from PCjr to PC.

I believe topbench displays the machine ID that it detects- you could run that with and without the cart inserted to see what it reports.

I do recall that the old booter game Spyhunter did not run on a PCjr. (I was CRUSHED as a kid when I bought it and it didn't work!)
I think booting to that disk with the cart installed might fix that. My buddy back then with a Racore dual floppy machine with a PC/PCjr switch on it was able to get spyhunter running IIRC.

Otherwise, there isn't very much software that I'm aware of that checks the ID, or if it does, it would be a game that would probably switch from 16 color to 4 color or turn off the 3 voice sound support, so I think the cart does more harm than good. :)
