(author here) Not quite, a 256 bytes PC intro CAN have decent non MIDI music as showcased here https://www.pouet.net/prod.php?which=79281 (won the "outstanding technical achievment" award) I did some intros in 32 bytes and 16 bytes having that "horrible buzzer", looks like some ASCII effects and a dutch gabber bassline is the maximum you can get in this category :D ( https://www.pouet.net/prod.php?which=76093)
