Try changing the output module in the SPU2-X sound plugin to directsound.
I done that and when i run the game the ps2 starts but the rate is 3.5fps the top bar says:ZeroGS 0.97.1 3.5fps| interace|bilinear| ps3.0(99003) error appears on the cmd log: GIFTAG error, size exceeded VU memory size 3ff
Yeah... don't use ZeroGS as graphic plugin, try the GSdx one.
when i use the GSdx one there is totally no video showing, just music playing and the same error pops up:GIFTAG error, size exceeded VU memory size 3ff
damn im bad at these stuff
