What's the difference between the sys and cfb versions of sys_fillrect/cfb_fillrect, sys_copyarea/cfb_copyarea, and sys_imageblit/cfb_imageblit? It seems that your patch changes from using cfb to sys mainly due to the fact the framebuffer is in RAM, but are there any advantages to using one over the other? I've searched the internet and the source files with little success. The reason why I'm asking about this is that there were recently some patches created specifically for Raspberry Pi devices that I think might benefit the GameCube/Wii framebuffer. For example, one of these patches optimizes imageblit for common bit depths by creating special cases for 16bpp and 32bpp (therefore allowing for constant folding). A copy of this specific patch can be found here: https://github.com/hglm/patches/blob/ma ... eblt.patch
