Graphic/Framerate problem - Guilty Gear XX /\ Core (J)

[IsshunSengeki]

Hey guys,
I've got the (J) .iso of Guilty Gear XX /\ Core and it isn't working all that well for me.
I get some colours not showing up, some other graphical glitches, as well as a bunch of slowdown and intermittent lag spikes (jumpy freezes).
Pictures in the attachments.
My computer specs:
Intel Core i5 2.4 GHz
Windows 7 Home Premium 32-bit
4GB RAM
Nvidia GeForce 330M 1GB VRAM

Can I change something within the Dolphin/computer settings to make it work?

Thanks in advance for your help, guys.
P.S. I did a search, and there was a 'perfect running' thread for this game, but it was posted back in 2009 (so I figured the thread was necro'd), last update was for revision 4147 or something. Does region matter here?

Try this setting http://www.dolphin-emu.org/performance.html
Tick "Safe Texture Cache" Normal mode

I'm actually surprised you can start the game. Are you using a recent revision? With NTSC-U version, the game doesn't boot since Marcosvit's FIFO changes.

Thanks admin89, I'll give that a go and report back.
StripTheSoul, yes, I'm using revision 6730. Apparently the game was running perfectly on revision 4741 using DolphinIL.exe (which wasn't included with the latest build).

That's the thread I got this information from.
