I watched this video recently because I was having trouble ripping a ps1 game from the disc and most of the suggestions I could find were imgburn which is windows only and not open source. Unlike the video I used Brasero on pop os 22.04 LTS. Another thing to note is the emulator I used was not picking up the game at first because you need both the cue file and bin file in the game folder unlike with ps2 emulation that requires just one file.
