If the keyboard does not work and is impossible to save/load and skip audio/video, this should help (tested with 0.61 official version):
Delete or rename wintest.exe from the game directory and copy mem.exe there (where to find it: XP - C:\WINDOWS\system32; Win 98 - c:/windows/command), rename mem.exe to wintest.exe and run the game. Now the keyboard should work fine.
With 9000 cycles was speed perfect on my computer with 2.5 GHz processor. There is also a sound patch that can be found at The Patches Scrolls http://www.patches-scrolls.de/
, but the game seemed to work fine without it. I picked out Gravis Ultrasound and sound was good, SB should work too.
