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.
