http://buildbot.orphis.net/jpcsp/ Jpcsp SVN r1525 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: r1517 Small improvements in sceMpeg: only enable faked Mpeg when MediaEngine is selected. sceMpegAvcDecode: take frameWidth from sceMpegCreate when receiving 0. r1518 Added compilation of several FPU and VFPU instructions. This improves slightly the performance of 3D applications. Added a test application to compare the performance of the code produced by the compiler to a real PSP: when the Java JIT is compiling the code generated by the compiler, it outperforms a real PSP! r1519 Improved PSP memory management to reflect the behavior on the real PSP: - area reserved at program startup - memory is allocated in 256-bytes chunks - stack size for the root thread - sceKernalCreateThread: check successful stack allocation Added a test application to verify these settings on a real PSP. r1520 Small code changes so that the Java JIT compiler can produce faster code: - ">> 2" produces faster code than "/ 4" - final methods are faster r1521 VideoEngine: avoid OutOfMemoryException when generating a lot of mipmaps. r1522 better implementation for sceAudioGetChannelRestLen r1523 EventFlag: do not context-switch when called inside a callback. r1524 Improved cheat support: - Added an experimental method to process the codes; - Extended CWCheat's jokers' support. Improved sceFont: - Fixed several functions; - Added new findings; - Implemented a dummy font output. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.126.238.100 ※ 編輯: choan 來自: 59.126.238.100 (05/30 00:14)
