Just run it without sound and it won't crash.

That looks like you are using an outdated
linux kernel. Can you try something >= 2.4.22-pre3
and see if the problem is still there?

Neither Pinball Fantasies nor Pinball Dreams
causes dosemu to exit, but where is to get a
Pinball Dreams?

I run 2.4.22-pre7 now. It's still the same.

it depends how you look at it. bitmap fonts use the VGA character size
of 9x16/14/8 where the 9th pixel is extended from the 8th.

This default X font vga.pcf uses 8x16 however.

Now the font spacing *looks* too large because of the aspect ratio.
Here we have a 720x400 window with an aspect ratio of 9:5 (1.8) instead of
the fullscreen 4:3 (1.33).

Too see what I mean, set
$_X_bilin_filt = (on)
(to filter out ugliness) and then press ctrl-alt-f.

I'm not sure what to do about this. Maybe DOSEMU should use 8x16 character
boxes even for bitmap fonts.

yes, I know about this. Haven't got around to test or try fixing this one
though.

Trying to fix it yourself would be very good of course! These are all
non-trivial bugs too fix, for you as well as for me.

Hi.

Note that items with higher number are probably harder to fix :)

1.
I've noticed when using bitmap fonts, the font spacing is too large. 
Where can this be fixed?

2.
A free DOS program named Impulse Tracker has prolems with
rendering it's text interface. It uses customized VGA font but it
continually flashes between the full screen interface and some random
garbage.

3. 
The Hard Rox  PC demo (great music) started working somewhere after 1.1.5 
(I think) but it crashes after some run time. 
the program prints this on the console
Coprocessor Error at eip=0000ec30
eax=0003d488 ebx=00000000 ecx=00000000 edx=00000013 esi=000427d4

I have reports of other issuses, but tell me if you want me to continue sending
that or should I rather spend my time trying fixing the actual code. It
might take me a while to learn my way arroun though.
