No.23929 hap Developer 8 hours ago	Isn't that just a recording of an old version of MAME?
No.23930 yoshi200213 Tester 7 hours ago	yes but it happens in the last version of mame
No.23931 hap Developer 6 hours ago	I mean the 9 year old OST video :D Can you tell that it's a PCB recording? OST on youtube aren't recommended as proof that there's a bug with the music.
No.23932 yoshi200213 Tester 5 hours ago	yes is a pcb recording.
No.23933 yoshi200213 Tester 5 hours ago	also theres no vibrato in old versions of mame like the 2020 versions.
No.23934 hap Developer 4 hours ago	I'd say it's more likely an emulator recording, MAME or M1 (M1 app uses MAME's sound emulation). I assume it's the DSP which wasn't emulated yet, the song sounds much flatter on that recording than on current MAME. Not just the missing vibrato on the chords.
