QuakeDS mod

The game

• the program, working state and game data have been squeezed into the four megabytes of
  main memory
• it requires either shareware or commercial pak files, Amiga
  and PC paks have been successfully used
• many total conversions and mods should work with a stock DS,
  assuming they respect
  the tiny memory size
• total conversion
  and mods which refuse to play on a stock DS will play on a DS with a compatible
  flash card when combined with the EXRAM build
• infrastructure-based wifi network gaming is supported
• ad-hoc DS/DS gaming is currently de-activated in this
  version
• there is full control configuration
• game saves work, although there may be some corruption
  using certain DLDI drivers - game saving is not guaranteed to work
  correctly in the EXRAM build (when used with a slot-2 DLDI)
• there's a crosshair
• there's view snapping and pen sensitivity settings
• there is a proper timebase, so the speed won't be
  inconsistent any more like it was in pre1
• there's an on-screen keyboard, for use in-game and with the
  console, and it is much more functional than before
• there are eight user-bindable 'touch buttons'
• access to the command line is now easier
• dodgy QuakeC compatibility has been improved

Graphics

• all software renderering has been moved
  over to using the DS' 3D hardware
• world textures are display 99% correctly, there may the
  occasional non-power-of-two texture wrapping glitch; Alias
  models are fully textured
• sprites (eg explosions) are now correctly rendered, and
  they now have their correct animated textures (ie they're not pink any
  more!)
• particles (eg blood effects) are also correctly rendered,
  and also come in a shade other than pink
• animated model skins are now (barely) supported
• the game uses faux vertex lighting, derived from the
  original lightmaps; light animations also work correctly
• there's no dynamic lighting and Alias models are not lit
• there are sky, water, sludge, lava and teleporter
  animations (the sky is now rendered correctly)
• the console now uses the Quake font from the chosen pak
  files
• the game uses hardware fogging for a light depth cue above
  ground,
  thick
  fog for below water
• there's a HUD
• GUI elements are transparent (with no more corruption)

Sound

• there's a full-blown custom ARM7 sound effects system, and
  it totally r0x0rs
• the sound system uses proper spatial positioning (it is
  stereo though...) - plug it into your speakers and subwoofer to hear
  all the effort I put into this!
• CD music has been dropped from this version...it may return

Tech info

• uses the libfat DLDI interface, so should hopefully work on
  all supported flash cards
• built using the devkitARM r20 toolchain
• textures and sounds are loaded from disk on demand - you will notice
  slow loading if you have certain types of cards, or low quality flash
  cards
• sound and texture memory is defragged in the background
• in-game performance has been improved but is still not hot,
  and I think this is as good as it's going to get
• rendering performance is very good (pause the game and move
  the camera if you don't believe me)
• performance is timed using a custom function-instrumenting
  profiler (a bit like gprof) and another system is used for recording
  the exact
  pad and screen input for later replaying
• the DS is put to sleep when the lid closes (disabled in
  this build)
• there is no texturing on brush or Alias models or images
  loaded from individual files - you must
  use pak files
