GPU Configuration
Pete's OpenGL 1.xx/2.xx
If you have speed issues with these configurations:
OpenGL 1.x:
* 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
* Change Framebuffer Textures to 2 or 3 and setting access to 3 Will move the work for swirls from yor CPU to the graphics card. Note: using this method battle swirls will not work if FSAA is enabled
OpenGL 2.x:
* 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 or 1 - note: this will introduce a 'load' when framebuffer effects are called (like at the beginning of a battle)
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:

CDR Config
In the PAL regions (Europe, Australia and much of Africa), FF9 had copy protection and thus when you run it in an emulator, you will just get a black screen. There are two was to get this to work on an emulator. The first is to use Subchannel reading (which at the moment, for the life of me I can't get working), and the other is patching.
To use patching, first of all you need the PPF patch files. The ones for PAL/UK can be found here. Others can be found by searching google (the site which has them cannot be linked here for legal reasons). The PAL/UK patch covers all English language PAL versions.
All you need to do then is to extract the archive to the 'patches' subdirectory of ePSXe and enable 'Auto PPF-patching' within ePSXe
FAQ
Q: I'm getting a lot of crashes in FMVs
A: Use ePSXe 1.5.2 or the latest version of PSXeven. ePSXe 1.6.0 is known to have issues in Final Fantasy IX
Q: The in-game text screens are slow after a battle and in the option menu. How do I fix it?
A: In-game menus in Final Fantasy IX are slow because it's hard to emulate the Play station's Frame-buffer in a hardware API. Setting a lower resolution like 640x480 will speed it up. Higher resolutions slow down the menus even more. Having a high end computer will speed them up as well. Alternatively, use a software plugin.
