Try different core= settings and the DosBox CVS.

Thanks for the suggestions!

core = normal, simple cause win32s error (Initialisation of a DLL failed; The process is terminating abnormally; then 'error 21'). dynamic as above.

Same behaviour with each core on CVS (using existing files; I can wipe + reinstall everything if it might help...)

which cvs? think that game should work fine (dynamic core)

CVS from http://www.aep-emu.de/cvscompile/dosbox.htm, downloaded about an hour ago. Exe labelled dosbox_15.03.2008.

Maybe try a different cvs build to be sure (gulikoza's for example).
Otherwise you're out of luck, i only tested the demo of the game some time ago.

gulikoza -- same story. Thanks for trying, though!

Could I ask what causes "INT:Inner level:Stack segment not writable"?

The emulated program is trying to write to an area of memory that is read-only (it's a code segment). Hence the name of the memory mode "Protected memory".

It could because a pointer is wrong in the emulated program, or it may have gotten completely trashed and is trying to execute garbage, which results in an invalid opcode.

I have not run this in DosBox myself, so can't help you on whether it works, sorry. =(

Nope. This error message is thrown when an interrupt gate's stack segment
selector points to a segment that is not writeable. Usually as you said "something"
went wrong way earlier though.

Now that is HOT!

just browse cpu.cpp for total hot-ness

Ok, well it has been 15 years since x86 assembly was my main focus =). Thanks for the clarification, either way, bad segment pointer, likely the result of a munged stack...if I can this evening I'll test out your game burbly, as I've been meaning to set up a Win 3.X install in Dosbox, just haven't had much need - been using my Pentium 3 box to just run it when I needed.

Well - thanks, all! I didn't expect this much help this quickly.

Demo does work under Dosbox.

I might try running directly under Vista... I tried such things on another PC before but none of the slowdown utilities I could find made it playable. Could anyone recommend one that's likely to work well with BIA? (Hope that's not too OT...)

If your going to run it in Vista without emulation then you'll need to use compatibility tab and apply 256 colors and 640x480....and if your running Aero this will screw up your desktop colors and revert back to Vista Basic if you like to switch between the game and your desktop.

Also the game will run too fast of course. I can't recommend any slowdown utilities since I hate them and they never work properly....ever.

Yup, I tried that -- colours turn out fine w/o anything screwing up. (Except you have to alt-tab out of the game and back as soon as it starts in order to get proper colours, but that's not much work.)

I've also had general misery with slowdown utils... good to know its not just because I'm a n00b. They just seemed like the only option left.

So your saying that the demo works fine for you but not the full game?

I've never tried the demo in DosBox just the full game......

I'm wondering if the version of Win32s your using is different from the version I used. Problem is I can't remember which version I used.....

Yes, I tried the demo this morning + it was fine.

win32s -- tried both the one on the game CD and from http://www.si-gamer.net/gulikoza/win/Win32s.zip .

Should work in the cvs now.
