If you're running retroarch from the command line, try looking in the folder that you're running the program from. So if you cd ~/games; retroarch then your videos will be saved in ~/games.

Also the relevant setting is recording_output_directory (mine was an empty string which is why it was saving to the pwd)

@MattyL42 said in The Last Starfighter Arcade?:

I was just wondering is it possible to play it on Retropie?

It would require Windows. There's always the unreleased Atari800/5200 prototype. It's not nearly screen-accurate, but it is completely period-accurate and obviously the home version that Atari planned to release.
