How many PS2-era games used JIT? I would be surprised if there were many of them - most games for the console were released between 2000 and 2006. JIT was still considered a fairly advanced and uncommon technology at the time.

A lot of PS2-era games unfortunately used various self-modifying executable tricks to swap code in and out of memory; Naughty Dog games are notorious for this. This got easier in the Xbox 360 and PS3 era where the vendors started banning self-modifying code as a matter of policy, probably because they recognized that they would need to emulate their own consoles in the future.

The PS2 is one of the most deeply cursed game console architectures (VU1 -> GS pipeline, VU1 microcode, use of the PS1 processor as IOP, etc) so it will be interesting to see how far this gets.
