I got [512gb]-Total.Recal.Rpi4-Wolfanoz from https://www.arcadepunks.com/download-raspberry-pi-4-images-newest-first/ and installed recalbox OS on an internal 2.5" hard drive, moved the files from the image to the hard drive and booted the computer from the hard drive connecting it as an usb with a USB to SATA adapter.

Is there a way as simple as this to emulate a bunch of games on a linux computer?
