dosemu too fast

dosemu too fast

[Ralf Engels]

Found a solution!
Who want's to implement it for real?

Dosbox was running a little bit too slow and Dosemu was running much too fast 
for playing x-com. 
So I tried to speed up dosbox (no success) and to slow down dosemu.

The following solution seems to be quite good. It does not waste processor 
power and seems to be a general way to slow down almost every dos program 
running in dosemu.

In /src/base/dev/timers.c add the following code to the function timer_tick 
(around line 137)

#endif

  // this function is called every 10 ms, so sleeping for 5ms slows down the 
program by 50%
  usleep(7000); // Ralf 70% slowdown

  /* compute the number of 100ticks since we started */


So, I have no plan to implement this for real, e.g. make a dosemu-option. Who 
want's to do it?

BR,
Ralf

I made some patches about it but never
got that finished yet.
You can get them here and see whether it
works for you or not:
https://sourceforge.net/tracker/?func=detail&aid=716137&group_id=49784&atid=457450
Those introduce a $_slowdown option but
perhaps require more work as to avoid
the timer bursts and some other nasty
side-effects.
