MK4 Vulkan 4x for Windows - blahm1d

Higher internal polygon rendering resolution with ORIGINAL game textures.
No remastered texture pack or game ROMs are included.

1. Extract the entire ZIP into a writable folder.
2. Put your compatible MK4 version 3.0 mk4.zip and tms320c32.zip in roms.
   Keep these ROM ZIPs zipped. Supply your own ROMs.
3. Double-click Play MK4 4x.bat.
4. Press Tab to configure controls. Default 5/6 insert coins; 1/2 start;
   Esc exits; F11 shows emulation speed.

Requires 64-bit Windows and a Vulkan-capable GPU with its vendor driver.
No Python or Vulkan SDK is required. Keep the bgfx directory with the EXE.
Settings, saves and screenshots stay in this portable folder's user directory.
Keep any existing installation and saves separate when extracting this package.

The 4x setting increases internal polygon resolution, preserving original
models, original textures and game behavior. The existing experimental v17
lighting is retained. This is an unofficial modified MAME build, not an
official MAME release. Performance varies with hardware and scene.
If needed, copy the launcher and change -mk4_vulkan_scale 4 to 2.
To diagnose ROM problems, run:
  mame-vulkan.exe mk4 -rompath roms -verifyroms
