No sound: no idea, did you configure everything ok and tried all different soundcards?
Slowness: it is a relative thing. There are settings in DOSBOX influencing speed. Also there is also a vast difference how a game runs on 450 Mhz Pentium3 or 3 Ghz Athlon/Pentium 4... (I mean it generally, i do not know Bedlam...).

Aha, i have to click that tiny little icon to do that 😉 perhaps it's an idea to make it more noticeable...
Anyway, the machine i'm tryings this on is a 2Ghz+ machine (or 3200 in AMD's system) so the emulation shouldnt be a problem, at least i think. I tried several soundcards but none of them gives sound ingame. Also nosound doesn't improve the fps.

BEDLAM? Isn't that an old CGA arcade game that had NO SOUND (Not even internal speaker)? 😕

According to Mobygames they list just one BEDLAM (newer, different). I have the other one (much, much older) lying around somewhere. Of course, it runs superb under DOSBox, but you've got to keep the cycles very low (100 or so) because it was meant for the XT PC (4.77MHz) 😁

It does say v2.0 on startup if that's what you mean by new version?

Anyway, shouldve read better i think: the game seems to start with a rate of CPU:2500 cycles. When i increase (not lower) this to about 15k the game runs quite smoothly. Playable for me i guess 😀

Now only for the sound, i can hardly imagine the game doesn't support sound at all since i can set it up and test it in the menu?
