one sounds different, some might say they sound the same but i found and ripped it from (somehow preserved for 35 years) data from a yamaha ym2612 sound chip (fm synthesizer) and a TI-PSG (programmable sound generator) one for sure is the recent 1991 prototype found on new years eve 2020 im not sure what the other one is but it sounds more unfinished and raw, its missing a minor amount of FM channels and the contents of said channels are slightly 'unfinished' and a few problems with the sound chip are reducing the quality of the audio it - you guess the audio duneboy (@SonicSaturnFan) specifically if you want to use any, feel free you don't need permission
you can also guess when its from
