c++ is a native language , java is a hle language so supposely it will be faster since a lot more optimizations can be done natively

And they did a good job. |

It will likely be quite a bit faster yes.

RE: Performance with same codes achievement as jpcsp
HLE = High Level Emulation
LLE = Low Level Emulation PSP has an OS which is a collection of modules. Those modules offer some API to handle any I/O devices without letting game developers directly to deal with hardware. HLE = API emulation LLE = Hardware emulation ppsspp and jpcsp are HLE because they don't try to emulate the hardware but run equivalent modules rewritten in native code. - critical code coded in Java are less efficient than one coded in native code through C++. The last comparison i saw between Java and C++ was biased in favor of Java because they compared with native code compiled through C++ in debug (unoptimized, the worst). - development in Java is simpler and easier to debug. |

RE: Performance with same codes achievement as jpcsp
jpcsp currently broken because java update
C++ easy to debug than java in term of code and optimized and stable i also don't understand they say java almost near speed to C++ i think they too biased for java we got alot of example C++ emulator pcsx2 , epsxe so on.... |
