CS:000 IP:0077 OP:f0 37 05 0a 02


This is from my Lost World Part 2 Mod. It does the same thing to other mods

I have this

OS: Windows XP (SP3)
RAM: 2gb
GFX: EVGA Nvidia 9800 GT
CPU: Core 2 duo 2.3 giga hurz

DOSbox Lages Wolfenstein3d with advance coding.

any help?

I think I had a problem like this. Use dosbox and tell me what happens.

i did use DOSbox but my mod has advance coding and it lags even with the speed is up

I don't personally know what the error is. But try running your mod with VDMsound instead of DosBox. See what happens. I have found that DosBox gives me some troubles. Not all secret passages move back 3 spaces and Fake Hitler fire balls go much faster than in VDMsound. Just a suggestion...

did that and still the NTVDM Erorr

NTVDM is a 16 bit Dos Emulator it comes with windows XP and stuff...

all i did in intstill my new gfx card and boom Error..

Strange tho Wolf3d SDL works fine.

Of course Wolf3d SDL works fine. It's a 32bit windows application...
You need a faster CPU for a higher Dosbox framerate.

The new graphic driver might caused system problems. Maybe the installation corrupted a few system files. Check if autoexec.nt, config.nt, command.com or any other important files aren't modified/corrupted. Run windows repair mode, a system check or whatever.

its strange..cause i redone my computer 2 time...and even i did re do my computer and i didn't install the gfx card driver i still get the NTVDM error.

How do i run repair mode?

Huh, redone? Installed xp again? I assume you haven't replaced, installed or modified anything system related besides the new graphics card since your last wolf3d play. You should install the graphics driver so that the card works properly. For the system repair/check: run "cmd" and type "sfc /scannow"

i did that and it was a no go v.v

That won't change it.. I know because the same thing is happeneing to me, I'm getting it as well.
It doesn't affect the game in any way, it's just there after you finish playing and I don't know why either. My EXE is running beautifully, I'm just left with the same message after playing.

Interesting, so you get the message after you close wolf3d, and so it does not interfere with the gameplay at all? For me, the message apear before the game starts, with close or ignore buttons.

It never comes for me before the game but it's always there after but doesnt affect playing in anyway what so ever.
