NeoPop/PS2 ...

is based on the neopop_uk's core v0.71 (so the last one) and I didn't sacrificed compatibility to speed up the emulator (the core is really sensitive to timing), but only made some little hack in the core to speed it up (ps2 related optimisations stuff). Unfortunately, due to timing constraints and the line based emulation, the emulator is not running at fullspeed (and I swear that making it running fast is really a pain...) however games are playable at a correct speed. Also sound emulation is not always perfect and this due to not fullspeed emulation.
