just in case some of you experience problems like me with MGS(slow XA sound when PC fps is activated,stuttering,etc...) using Pete's DSound here's a solution: use Eternal spu 1.1 and enable the new SPU IRQ--wait CPU action function similar to SPU IRQ queue in Pete's DSound Plugin, and remember to deactivate SPU IRQ hack in ePSXe and enable PC FPS calculation in Pete's GPU.
