JIT emulators for the psp?

yeah, i wonder 3 things

1. what does JIT (just in time) code really mean?

2. is there any other emus besides gpSP with JIT code for the psp that has been released?

3. is it possible that other emus will runs faster (SNESX9TYL etc) if they were reprogrammed in JIT?

JIT(just-in-time) is a way of tracking errors and debugging them. It is implemented in some of the most advanced programming suits (ie Microsoft Visual Studio fromm 2002 and up). It isn't a programming language so you can't make games in it.

Well basically if we add dynamic recompiling to current emulators such as snes and dgen we easily can get full 99% speed, but things liek Saturn and Sega CD will require quite specialized dynarec code and alot of experience *cough* Strnmnrm (but let him work on n64 for now)

Not true. Dynarec pretty much requires a fairly clock speed in order to gain results over an interpreter. An assembly language interpreter would be favorable for snes or genesis.
