QuakeSpasm-DC

A Sega Dreamcast port of QuakeSpasm with a native PowerVR renderer.

Features

• Native PVR renderer — geometry streams straight to the Tile Accelerator.
• SH4 hardware math (sh4zam).
• Hardware table fog, per-vertex lighting with dynamic lights, and lightstyle animation.
• Alias (.mdl) models, sky (flat / scrolling / skybox), warped water, particles, sprites, entity shadows, and underwater warp.
• Hardware mipmaps for square world textures; N64-style translucent overlay HUD.
• VMU save games (zlib-compressed), plus config stored on the VMU.

Requirements

• KallistiOS (with the SH4 toolchain)
• SDL2, built for the Dreamcast
• sh4zam — SH4 SIMD math
• zlib (kos-ports)
• mkdcdisc — builds the disc image

Building

Source your KallistiOS environment first, then build the ELF:

source /opt/toolchains/dc/kos/environ.sh
cd Quake
./build_dreamcast.sh elf

The native PVR renderer is on by default (USE_PVR_RENDER=1); build with USE_PVR_RENDER=0 to fall back to the GLdc path.

Making the CDI

Put your pak0.pak (and optional pak1.pak / OGG music) in Dreamcast/cd/id1/, then run the full build to compile, link, and package the disc image:

cd Quake
./build_dreamcast.sh          # produces quakespasm.cdi

Boot the resulting quakespasm.cdi on real hardware (GDEMU / ODE) or an emulator such as Flycast or Redream.
