Thanks!
Keyboard remapping was almost there, but I didn’t have the time to make the options for it. The input code does go through a mapping table though because I had remapping in mind, so future versions will definitely allow for it.
I noticed the sound lag on windows. I’ll try to fix that at some point. I’m using a 3rd party audio library (libmikmod), and I’ll have to dig into their windows backend to see what’s going wrong. The bug is windows-only. GNU/Linux and SGI IRIX play the sound effects correctly.
