Jpcsp SVN r1348 is released.JPCSP is a PlayStation Portable(PSP) emulator which is written in JAVA. JPCSP is the first PSP emulator that is written in JAVA. Most people think java is too slow. But Shadow and his team has proven us wrong. The newest Java versions are almost as fast as C which makes it very interesting for emu dev's. Shadow and his team are working day and night with pleasure on the emu, many coders have dedicated to the project. Because it's written in java many young devs find it interesting to learn how the emulator works.

Jpcsp SVN changelog:
r1346
Fix for Homebrew: hack for preemptive scheduling is no longer required. This is now correctly implemented by interrupts.
r1347
Fix in VideoEngine: base (and also probably baseOffset) are not list-specific but global variables of the GE. Tested on "Red Bull X-Fighters NPEZ00100".
r1348
- Implemented a Vertex cache: this option has to be activated in the compatibility settings. It improves performance on several applications, but not on all of them.
- Improved vertex shader: skinning (morphing) is now done in the shader when the shader option is enabled.
- Fix several problems in shader
- Other small performance improvement in VideoEngine: e.g. trying the reduce the overhead of initRendering() for each PRIM command.
Combining Vertex cache and shader options gives a huge performance boost in skinning.pbp demo: 40 FPS instead of 8 FPS on my hardware.
