Jpcsp SVN r1764 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:
r1761
Fixed saving of GE to PSP memory when GE is smaller than FB (different
bufferwidth values).
Fixed one display problem when "Only GE" is enabled (related to incorrect state
handling for enable/disableClientState).
r1762
Improved REGION, SCISSOR and viewport implementation in the VideoEngine. Also
implemented the viewport "flips" (upside-down and left-to-right) to better match
the PSP (tested using 3DStudio).
r1763
Updated 3DStudio to tests viewport "flips" (width < 0 or height < 0).
r1764
Fixed the implementation of the "Use Vertex Cache" option. It was broken by the
VideoEngine redesign.
