It did not ..

I went at it with the INTRSPY program from Schulman's Undocumented
DOS, to see what comic.exe tries to achieve. The only difference I
found was when comic.exe calls int 10 function 12h, which happens
once:

(on X)
12h: video subsys conf,   AX=1200  BX=0010
12h: result:              AX=1200  BX=0003

(on console)
12h: video subsys conf,   AX=1200  BX=0010
12h: result:              AX=1203  BX=0003

If I understand you correctly the "console" result comes from the
real video card, while the "X" result comes from dosemu's VGA
emulator. But the return value of AX should not make any
difference, or should it? Can you suggest any other diagnostics?
