Jpcsp SVN r2168 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:
r2167
Implemented support for the following PSP video operations in shaders: stencil, color mask, alpha test, blend test.
This shader implementation is improving the compatibility (tested using "3D Studio"), but has a negative performance impact (lower FPS). This is these new functions are available are options in the configuration settings: "enable shader implementation for the Stencil Test" and "enable the shader implementation for the Color Mask". See additional info in the README.txt. These options might improve the graphics display or reveal graphics previously missing.
Improved the viewport implementation to better match the PSP (tested using "3D Studio").
New findings on alpha test parameters.
Improved CLEAR video command.
r2168
Fix for shader compilation errors:
- global function round requires "#version 130" or later
- unable to find compatible overloaded function "texelFetch(sampler2D, ivec2, int)"
