ScummVM is a program which allows you to run certain classic graphical point-and-click adventure games, provided you already have their data files. The clever part about this: ScummVM just replaces the executables shipped with the game, allowing you to play them on systems for which they were never designed!The current Beta 4 for PSP has these changes:

  • Graphics drawing speedup
  • Rewrite of input code – you can now save in Simon games (some mappings have changed, read the README!)
  • Added cursor acceleration for 640×480 games
  • Added 4:3 (aspect ratio) video mode
  • Added MPEG2 (re-encoded Broken Sword cutscenes) support
  • Added Vorbis support
  • Fixed crash in launcher when selecting language
  • Fixed hang at MI1 final chapter screen
  • Fixed Broken Sword 2 menu issues
