Corresponding source for blahm1d MK4 Vulkan 4x polygons / 2x textures preview
Full modified MAME source and bundled third-party sources/licenses are included.
Build environment: MSYS2 UCRT64 GCC 16.2.0, release64; embedded SPIR-V shader.
Install MAME's documented Windows dependencies. See
docs/source/initialsetup/compilingmame.rst. From a UCRT64 shell:
    make -j8 REGENIE=1 NOWERROR=1
This builds modified MAME as mame.exe. For an existing full release64 tree:
    MK4_VK_TARGET=mame-vulkan-halftex.exe bash tools/mk4-vulkan/build.sh
The public binary is stripped with GNU strip --strip-all after validation.
The runtime archive contains the compatible 2x texture pack and launch BAT files.
The pack converter is supplied for reference; it requires separate 4x artwork
masters and Pillow. Developer tools are not required to play.
No clean-room or bit-identical reproducibility claim is made.
Original software copyright and license notices are retained.
