Worked On

• PSP
  • Suspend/resume support
  • Plugin support (ELF loader)
  • Console-oriented virtual keyboard
  • D-pad directional support
  • Eliminating the evil undead flickering bug (it was a tough one)
  • Refactoring, redesign and cleanup

Working On

• PSP
  • Optimization
    • Adding PSP profiling support to the trunk - done
    • Moving all buffers to uncached space
      • Doesn't seem like a great idea. Some parts of the code need the buffers to be cached, particularly if they access small pieces. Audio buffers absolutely MUST be cached for decent speed.
      • Memcopy can be greatly improved with alignment, rotation of unaligned bits, and using the VFPU cache.
    • Possibly adding PSP MP3 HW support
      • About 8% speedup in some games
      • Looks like HW MP3 can only handle 2 MP3s at a time... should be enough usually.
    • Speeding up video decompression using vector unit
      • Doesn't seem likely for smush - not much parallel processing
    • Possibly speeding up music processing somehow?
      • Timidity may be a good option here

To Do

• PSP
  • MP3 playback with Media Engine
  • Optimize speed in general
  • Optimize video playback speed
  • Use libTimidity for music
• Generic virtual keyboard: take my keyboard and make it available to all. Involves switching from bitmaps to vectors.
• Generic ELF loader
