But first step: plug out that CPU labelled "Celeron" from your socket, and place something in it which really works at 2GHz 😜 - i already could test this: Celeron CPUs are typically half as fast as "real" CPUs offering the same speed! So 10000 cycles 😜 (A real machine with the hardwares you have should really be able to run fine on 20000 cycles). You may also set frameskip to 2 (DOS things run at at least 60Hz, so it would result 20FPS. Enough for continous movement while it puts less pressure on your hardware).
By the way it might happen too if you have a not so good sound equipment that it can not work how it should. As i tried out i experienced that producing continous sound on for example an AC97 integrated card is much trickier than with a "real" sound card. There are settings in the config file relating to this too - try to set the pre - buffering higher what should make the sound better. However it will also make the sound more delayed (might be annoying for effects).
Left this dictatoric junk. No. IV.
