GPU Configuration
Pete's OpenGL 1.xx/2.xx

If you have speed issues with these configurations:
OpenGL1:

• Lower the resoloution to 640x480
• Make sure FSAA and anistropic filtering is off in your graphics card's control panel - PSX Emulation does not support AF
• Set 'Hi-Res Textures' to 0
• Change Framebuffer Textures to 3 as it may work better on some (ATi) cards. Any other settings will remove the battle swirls

OpenGL2:

• Make sure FSAA and anistropic filtering is off in your graphics card's control panel - OpenGL2 does not support FSAA or AF
• Lower the internal X/Y resoloution to 1/1
• Disable 'Screen Filter'
• Enable 'No render-to-texture'
• Lower the resoloution to 640x480
• Change Framebuffer Effects to 2 - note: this will introduce a 'load' when framebuffer effects are called (like at the beginning of a battle) To make the game playable with these setting, Special Game Fixes need to be enabled.

Bear in mind that ATi cards do not support 'Very High X', you have to set this to 'High'

Eternal SPU
Under sound config, make sure the top 3 and only the top three checkboxes are enabled. Then use this Config in Eternal SPU:
