squarepusher2 from PSX Scene, has updated his version of SNES9x for PS3, he has made quite a lot of improvements and the Emulator now runs a lot faster, here is a quote from the Read Me:

===================

Build 4.4.8 (03-04-2011)

===================

* Very big performance and lag reduction optimizations. The previous builds

were indeed very laggy - this should be a very big improvement on that front.

* You can now use two shaders at once - we call this ‘Custom Scaling/ Dual

Shader’ mode. A scaling factor (from 1 to 4x) can be specified.

Some great graphical effects can be achieved by combining shaders.

* Shader presets have been added. Shader presets are configuration files that

automatically configure the settings for ‘Shader 1′, ‘Shader 2′, ‘Hardware

Filtering Shader 1′, ‘Hardware Filtering Shader 2′, ‘Scaling Factor’ and

‘Overscan’. You can create your own shader presets - they are just

plain-text files stored in USRDIR/presets.

* Controllers can now be individually configured - you can specifically

configure the controls for a controller connected to a specific port/

number.

* Cheat input has been made less buggy. With the ‘New’ control scheme -

L2 + Analog Stick Right Down will still input cheats with the OSK, but

it will add a generic label (simply the cheatcode itself as a label)

until you rename this generic label by triggering the action ‘Input

Cheatlabel’. The ‘New’ control scheme has this hooked up to ‘L2 + R2 +

Analog Stick Right - Down’. This can of course be reconfigured to any

button / button-combo you see fit.

* Fixed interlaced games like Rise Of The Robots - were displaying

glitched graphics before in version 4.4.7.

* Added a homebrew SNES game by Themaister. Game logic is semi-hooked

up - paddle works, ball bounces off the paddle, just scoring has to

be added. Anyway, this has mostly been a 3-day exercise in SNES ASM. This is just for illustrative purposes.

* Added some shader variations and some new shaders - HQ4x, 4xBR -
