I'm writing a program that's going to need access to SVGA modes and I've
got a few questions. The docs say that DJGPP can handle any SVGA mode it
has a driver for as long as it's 256-color. What would I need to do to
use HighColor or TrueColor? Do I have to write it all from scratch or
will DJGPP still be able to give me a linear pixel frame at 0xD000000?
Second question is the one that everybody got bored with a long time
ago. I want to release this as a mix 'tween freeware and shareware -
freeware that accepts donations. So far, everything except the
_go32_dpmi* functions isn't FSF code - if I use the DJGPP standard
graphics interface does that put me under any special restrictions? I
don't think it will since I'll probably release the source too, but I'm
just checking before I get any time invested in those graphics drivers.
Third question is has anybody done this before? I don't relish
writing drivers for several SVGA modes and I'd love to mooch them off
someone else. Maybe I could use Windows drivers? Are there any other
standards for this kind of thing?
Fourth question belongs in a separate post.
And now you get a lollipop for having read this while thing. :)
