Version 2.0 of my Allegro library is about 60/70% done. This a game programming library for djgpp which provides a range of graphics primitives, low level access to the mouse, keyboard and millisecond timers, file compression, fixed point maths, and a set of simple GUI routines. The major new feature in version 2.0 is support for svga graphics modes (the original version only worked in mode 13h). So far I have written a driver that uses real mode VESA bank switching functions, and one that programs my Tseng ET4000 directly at register level. And the real mode VESA calls are a killer as far as speed is concerned. On some simple tests the ET4000 driver goes over twice as fast as the VESA one. So, I would like to add register level support for more cards (it is generally only a matter of a couple of port writes). To do that, though, I need some kind people who would be willing to test it for me. So, if you are interested in helping with this, please email me (slh100 AT tower DOT york DOT ac DOT uk) and let me know what sort of video card you have.... Also, I would really like to add support for VESA 2.0 linear framebuffers, but my card doesn't support this. If anyone had a card capable of using a linear buffer, or even better, some example code that uses this feature, I would _really_ like to hear from you :-) Shawn Hargreaves If God is omnipotent, can he make a http://www.york.ac.uk/~slh100/ rock so heavy that he cannot lift it?
