I come up with another 2 suggestions...
- On the title screen, when the title music has ended playing, automatically load a replay/demo lump (or a preset one), which plays back, while the player has still access to the menu ala Classic Sonic games. Also in case of long title screen musics and/or looping enabled for the title screen music (or just detected modifience on music.dta, which i have), then instead of waiting for the music to end, make a 10-15 second delay before starting the demo sequence, while tuneslot stays during the demo playback (aka don't change the music).
- Make the Jingles (most notably Invincibility and Speed shoe theme) doesn't restart the music, when poping another one of the same power-up, thus actually "enjoying" custom Jingle themes...
