Not sure why this happens, hoping someone could shed some light on the topic. Pizza Tycoon immediate bottoms out when the mouse is moved (but not before then), while running under VDMSound. Anyone have any ideas, maybe a possible fix?

How about without VDMSound?!
Also, what OS are you running on?

Okay, here we go.
I grabbed my Pizza Tycoon CD, installed it, and here's what I've come up with (preliminarily):

The program starts with a batch file which loads a TSR (via sound\sound.com) for the sound:

1Creative Sound Blaster FM-Driver  Version 1.34
2Copyright (c) Creative Labs, Inc.,  1990-1993.  All rights reserved.
3Copyright (c) Creative Technology Ltd,  1990-1993.  All rights reserved.
4
5        SB16 / SB Pro 2 / MCV Pro 2
6
7Driver's I/O address set at 220 Hex
8Driver installed at INT 81H.

Then runs PT.exe.
The sound.com runs and terminates fine, but when I attempt to load PT.EXE (both alone and through the batch) I get a garbled screen (CGA double-width flipped characters, you know what I'm talking about) and then an abrupt exit. (I tried taking a screenshot of the garbled screen, but SnagIt insisted I wasn't in full-screen DOS (whatever...))

Anyway, here's some debug code for you. Maybe it'll shed some light on this (different, but equally bad) situation.

When I ran PT.EXE plain without VDMSound, I got a really funkadelic flashing pink scanline-esque screen. More tests later, I suppose.

According to the log, PT.EXE self-terminated after 2s. Probably gave an error (hence the garbled screen?) Question now is, what was the error all about? If you o in windowed-mode with the garbled screen do you get graohics or text or just black screen? If it looks like a text screen (even if blank), can you try to copy all the window and paste it somehwere?

Oh, BTW, does the game appear to use DOS4GW or another extender? Easy to test -- in LaunchPad disable DPMI support and see if the game bitches about it.

V.

It doesn't just appear to use DOS4GW, it does use DOS4GW. 😀
