well i started with v20, so I should probably update and redo my modifications that are still needed.
i'm waiting on the multi pitch playback trick and channel splitting of identical sounds.
as i said the dos version used three sound channels for sound effects, and if none were free the sound effect was skipped. However, even if the instrument played for a while after (the boing lasts a second at least), after a half a second or so the channel wold be considered free even if the sound WAS still playing.
I'm pretty sure amiga behaved different with ONE channel dedicated to sound effects and three to the music, with all effects overwriting each other. The single ohno when clicking nuke was because of this.
oh, by the way. compare fun 3's preview on lemmix vs dos. it seems lemmings uses a smart scaling algo that when choosing pixels prefers non background ones when scaling down.
Also it seems there is a genuine flaw in the amiga version. it's not that changing stuff with the keyboard is locked out, because it's not. it's that there is no key to increase or decrease rate. if the key existed, it would work paused.
Seems i will need to actualyl get amiga lemmings for myself to test.
