Hi namida, thanks for the info!

I think I've found a reasonable solution: With the "SLAMRACING" cheat, you can instantly beat a level by pressing Num5. That way I can cycle through the songs quickly.

Cheers.

Hey guys,
I've recently done a playthrough recording of Lemmings 1. I've used lem-fix2.exe to make sure every level had different music.
In ONML, the music changes whenever you beat a level, and whenever you start up the game you start with song 1 regardless of the level you select. This would be bad for a playthrough recording because e.g. if I only recorded 1 level per play session every level would have the same music. Is there something like lem-fix for ONML?
The only other workarounds I could think of would be leaving on my PC for weeks or replaying some Tame levels to "catch up" on the music.
