Add an option to downscale hi-res views
2020-08-13Add an option to downscale hi-res viewsJustin Weiss
Some older devices that use gpu_unai don't have a high enough resolution to display all of the pixels in high-res mode. There's a setting in unai to skip rendering of these pixels, but it's not connected to the libretro frontend, and does not appear to be used in the gpulib implementation at all. This commit adds a gpu_unai setting, Enable Hi-Res Downscaling, that will enable pixel skipping and blit only the pixels actually rendered into a buffer no larger than 384x240. This buffer is then treated as the actual framebuffer by gpulib and the libretro frontend.

2020-02-08gpulib: fix out-of-bounds reads in do_cmd_buffer()Daniel Silsby
When gpu.cmd_buffer[] is filling up, and the last 1 or 2 words in it are the beginning of a new vram read/write cmd, do_cmd_buffer() would access out-of-bounds, reading garbage pos/size data. Fixes corrupted gfx in this PS1 .exe test utility: https://github.com/PeterLemon/PSX/tree/master/CPUTest/CPU/LOADSTORE/LW (This and all similar tests on Peter's site). Note that gfx access in this utility is done entirely through cmds given through GPUwriteData(), i.e. direct CPU->GP0 stores, not DMA.
