Using 0.74 and a standard conf file I am attempting to play TV Sports Football. The game seemingly runs fine up until game play is supposed to begin, either accessed via an actual game or via 'practice plays'.

The graphics go screwy and the game appears to freeze at this point.

I have tried:
cores - normal, auto
cputype - auto, 386, 386_prefetch
machine - ega, vga_only, svga_s3
umb/xms/ems - on/off

I also tried the SVN version, which actually goes to a green screen rather than showing garbage at the freeze. So it appears to be handling it womewhat differently.

Hopefully that is enough details for help. Thanks.

This game actually has a few known issues.

The hang is caused by a game bug that reads the interrupt table from a null pointer, and is avoided on real systems because of how the interrupt table is typically arranged. A workaround program is attached for the issue.

There are some graphics that appear glitchy, but are supposed to be hidden when the display is blanked, and blanking is currently only supported with machine=vgaonly (NB: there is no underscore in "vgaonly").

The speaker sound isn't working in DOSBox, but it might work after hal's timer and speaker rewrite.
