Atari SDL patch for CTPCI/Radeon soon

After several, quite intensive days of patching and tests I’ve managed to add CTPCI/ATI Radeon support to Atari SDL 1.2 port. Soon the changes should appear in the main SDL repository.

The only issues that I have are in 8-bit videomodes when VsetRGB() is called frequently (luckily it’s only visible in pmDoom and pmHexen). Also SDL isn’t shutting down properly under FreeMINT because of XBIOS error, everything is fine under TOS.

Below there are sample photos of SDL projects which I have tested (GRAFX2 2.4wip, pmDoom, pmHexen, ScummVM and Reminiscence). As you can see everything looks fine.
