Spent at least three years of development, but couldn't be bothered to spend 15 minutes to write up how any living soul would use it without downloading and compiling the project to see help text from the .exe.
Step 1, click "Open Nes" and select a game.
Step 2, (optional) select or create a profile.
Step 3, click "Save Snes", a file will be created in the same folder as your Nes game.
Step 4, play on Snes hardware or Snes emulator.
Step 5, (Optional) click "Load SRM" and select the SRM file(s) generated by the Nes emulator,
feedback will be saved to the profile so the game can run faster after repeating steps 1-4.
