This is for switching code pages. I think what you want is to implement SVGA, not VGA, right? First do a graphics initialization include, return value, then initialize again. This graphics driver is fairly good, but the support isn't good enough.

The following is quoted from hhhhhh's post at 2003-8-14 18:49:14: Wrong. VESA is a software standard interface created because different manufacturers' SVGA graphics cards had different specifications. The most widely used one at present is VESA 2.0. The graphics.h file in TUBRO C does not have functions supporting VESA; as for DJGPP, I don't know. If you write it in ASM, you first need to know whether your BIOS supports VESA 2.0. If it doesn't, you need to use an add-on. univbe.exe is a good program, recommended. |

Right, graphics.h doesn't have functions supporting vesa, but if you copy svga256.bgi into C's system program directory and compile, it will work. I don't like using univbe.exe.

It's not from bc or tc, it's an SVGA graphics interface program, so then you can only use univbe.exe

..........Here's a suggestion: go to a DOS game development website. Discussing it here probably won't lead to any result.
