Emulator
Don't use .wav files for emulators, use .mzf files!
Physical Machines
Buy a cheap car adapter from your local shop (I don't recommend eBay because of scammers, got scammed as I thought i got an RF to VGA adapter i just got wires!
). Personally, I would go with a popular/known brand. I use a Polaroid Car Adapter (model no. WM1C-P) that I bought from ASDA for a few pounds so they are really cheap! Plug-in the headphone jack into your phone or computer and play the .wav file (usually converted from .mzf). If done correctly, your machine will start to load (e.g. LOADING Munchies) and a message will appear on your screen. Once the audio track is finished, you should be able to play the game/use the software you loaded in!
The format of files is such that two copies (one copy + backup copy) are always stored, so once the first copy has been loaded with success the program should be ready on your machine (but the audio file will still be playing).
