OK, the file I was thinking of is here:

It is the AMMO GUIDE ver 3.0 and the update file.

I can not get it to run on my XP machine. It ran fine when I was running Windows ME (icky). So can give it a try.
It will give info on the cartridge and you can put the image side by side with other cartridges.
