I've managed to pull off a setup that runs Klonoa 2 nearly perfectly in PCSX2. That includes the sound, and video (with of course, slight mess ups here and there.)
It used to be nearly unplayable because of the noise artifacts, and lack of music. I tried even using the latest SPU plugin from Pete, and that only caused laggy sounding music. (but took away artifacts.)
This was until I found the ZeroSPU2 plugin, which you can find here. http://www.zophar.net/utili...
I've tried it in PCSX2 1.0.0, but there was incompatibility issues (it would crash before game) So I tried going to 0.9.8, and guess what? It worked nearly flawlessly. I've been around looking on the PCSX2 forums, and there isn't very much support for Klonoa 2, so I hope this can help.

Copy all files to a folder, add the zerospu plugin to the plugins folder, then run pcsx2.
There has been issues regarding bad effects in-game, and this is my fix.
Set the default graphics plugin (4600 SSE41) to D3D11, Blend BFF, allow 8bit textures, and set texture filtering on.
Also, go to emulation settings, then go to EE/IOP, set round mode to "Nearest"
Then go to VU's, then set round mode to "Nearest"
Also start game in "Fast" mode, or it'll get stuck at boot!
Hope this has helped all fellow Klonoa fans wishing to play Klonoa 2 on their PC's!
Incase you were wondering, my PC Specs are
Graphics: GTX 760
(That's all that really matters)
