Images, configuration, and split files for AutoSplit (https://github.com/Toufool/Auto-Split). The images are sized to native NES resolution and work for me in NEStopia at 5x scaling. I'd imagine this could work with RGB input from real hardware as well, but I'm not sure about the palettes in that case.

It may be easy to accumulate some fool's gold in the Mario splits if you sometimes get an 11th coin on the 2nd life and sometimes on the 3rd. And if you reroute Tetris, you probably want to completely clear those splits.
