Hey Jonny,
I just downloaded the game but it comes up as an .nes file (I'll include a screenshot)
I'm a Mac user and haven't used simulators before.(I'm old)
Where's the best place to go for a walkthrough?
Best,
-Aaron-
Thanks for downloading Aaron!
I recommend using OpenEmu — it's free, works great, and is very beginner-friendly.
You can download it here: https://openemu.org
Once it's installed, just drag and drop the .NES file into the app, and it should show up in your game library. Then just double-click to play.
Have fun with the game!
