Hi.
How can I view or dump the VGA video ram to an image using emulators, or from ms-dos itself?
Dosbox debugger worked perfect with "MCGA" mode, in which every pixel is a byte in memory. But the results with mode X games were not good. I converted the dump to an indexed 256 colour image, and I (kind of) saw a "screenshot" of the VRAM, but it was distorted because (I think) it only gets bytes from one VGA plane.
Is there any other way?.
I thought I could write a little program which could reside in ram, and it would be able to get the bytes from all 4 planes after a key press or something. But I don't know if that's even possible with MS-DOS.
Thanks.
