What dosbox version and what OS?

DosBox version 0.70 running on Windows XP. MS Dos 6.22 also had this problem.

Try loading UniVBE

You will most likely need to www.google.com for it

It is a legal free VESA driver/TSR for DOS.

Apparently DOSBox does not emulate VESA for all the video modes.

It is your best shot IMHO, at least if it fails it'll be one step closer to isolating the fault. 😎

Thanks for the suggestion. Unfortunately, I couldn't install UniVBE because it doesn't support my current video card (NVIDIA Quadro FX560). Are there any alternatives? If not, it's really no big deal since I don't need the video playback to still enjoy the game. It just seems kind of strange that the opening video clip plays but the remaining video clips don't (well, they play aurally but visually are just a bunch of static).

dosbox emulates a s3 gfx card, so you would configure it for that card
not your nvidia one (actually the univbe installer/configure thing should
automatically detect the s3 inside dosbox).
What problem does occur exactly? Maybe post a screenshot.

Basically, it's a message saying "No supported SuperVGA chip detected!" It's in the DosBox command prompt. I get this message with every UniVBE executable I try to run.

Well then, second question remains.

When you say it happens in MS-DOS 6.22, do you mean MS-DOS 6.22 within DOSBox, or booted off real hardware ?
