* libretro core * Bringing citra libretro implementation over * libretro: hook up vulkan renderer * libretro: github actions * libretro: gyro * libretro: core options v2 * libretro: on ios turn off shader jit if unavailable * moltenvk 1.3.0 introduces 8-bit indexes but allocates 16-bit for metal; this ends up allocating stream buffer * 2 = 132MiB. Instead, just use 16-bit indexes. (This will be necessary for standalone when bumping moltenvk version.) * libretro core: address review feedback * libretro: microphone support * cmake: Add ENABLE_ROOM_STANDALONE to list of incompatible libretro flags * libretro: proper initial geometry * libretro: fix software renderer * libretro: address review feedback * .github/libretro.yml: Pin macOS runners at macOS 26 * ci: Remove explicit selection of Xcode 16.0 * .github/libretro.yml: remove unnecessary windows builder apt commands * .github/libretro.yml: bump min macos version to 11.0 * ci: Re-enable CI jobs for all libretro cores This is under the condition that we don't introduce build cache for these builds --------- Co-authored-by: OpenSauce04 <opensauce04@gmail.com> Co-authored-by: PabloMK7 <hackyglitch2@gmail.com>
