Jpcsp SVN r1598 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:

create VPL with 8-bytes aligned size. Tested on PSP.

samples.
r1598
Added async related check in sceIoClose.

Improved scePsmf struct and implemented scePsmfGetNumberOfStreams.

Reworked charset conversion in Utilities:
- Removed global charset conversion in readStringNZ and writeStringNZ (not every
usage of these functions supports charset changes);
- Introduced Shift-JIS charset for Japanese applications;
- Made charset conversion a more external process (with dedicated function).

Improved video processing in sceMpeg:
- Added check for 0 frame width from sceMpegCreate;
- Allow usage of real video dimensions (from Media Engine) in writeVideoImage;
- When enabled, allow the Media Engine to supply the real video's timestamp;
- Really implemented sceMpegUnRegistStream and added checks for audio/video sync
when only one of them exists.
