Here is a floppy I found in a box of floppies from a thrift store. The label was hand written but this looks like it was a copy of the original floppy.
If you try it out and the files are not correct, let me know and I will delete it from the site.
This is an NES Emulator that fits onto a floppy disk and can fit a few roms on the same floppy! I used this when I was in high school to play NES games on the school computers. lol 😛
P.S. This is only an emulator, you must provide your own NES Roms.
