The problem I'm having is with the sound. I think its loading to fast. I'm using Pcsx2 0.9.6.
This is my computer specs:
Vista 64bit
4Gb ram
ATI 4600 series
AMD X-2 Ultra Core
If the game is playing too fast (and therefore the sound is going too fast) you need to set frame limit in the CPU section.
Press tab or F4 or go to config->cpu and set to limit.
The song starts playing perfect but when the sword comes it slows down.
Do you have Vsync enabled in Gsdx's window? if so try turning it off.
It would help if you show us your settings.
For sound I'm using SPU2
For Graphics I'm using GDSX 890
For Cpu I'm using Limit
For speedhacks I'm using Cycle X2
