Here's the latest revision of the Java-based PlayStation Portable emulator project for Windows, JPCSP.

Changelogs:

• revision 2190:
  • 2 syscalls (sceGameUpdate) to ignore
• revision 2189:
  • A lot of improvements and code clean-up to better support the screen/window resizing.
  • The option to enable/disable the viewport filter has been removed: it is automatically activated when the window is resized.
  • The screen can be resized using the 1x, 2x and 3x options from the menu or by simply resizing the window with the mouse. The aspect ratio is preserved.
  • The resizing is now working when used combined with the "Saved GE to texture" or "Only GE" options. The screen looks better when using one of these 2 options.
  • The option "Use native shader CLUTs" should also be compatible.
  • The "black square" problem on the top left corner as reported for some games should also be fixed.
• revision 2188:
  • Improved compatibility of sceKernelLoadModule: added delay when loading an HLE module.
  • Added debug logging to the display to track the "black screen" problem reported by some users.
