(r02 was not posted to the WIP thread) byuu says: Internally, all color is processed with 30-bit precision. The filters also operate at 30-bit depth. There's a new config file setting, video.depth, which defaults to 24. This causes the final output to downsample to 24-bit, as most will require. If you set it to 30-bit, the downsampling will not occur, and bsnes will ask ruby for a 30-bit surface. If you don't have one available, you're going to get bad colors. Or maybe even a crash with OpenGL. I don't yet have detection code to make sure you have an appropriate visual in place. 30-bit mode will really only work if you are running Linux, running Xorg at Depth 30, use the OpenGL or XShm driver, have an nVidia Quadro or AMD FireGL card with the official drivers, and have a 30-bit capable monitor. Lots of planning and work for very little gain here, but it's nice that it's finally finished. Oh, I had to change the contrast/brightness formulas a tiny bit, but they still work and look nice. |
