Following news are comming from brakken / http://www.tehskeen.com :

Askot has released a new version of his modified port of SNES9X v1.43 for the Nintendo Wii/GameCube. SNES9X is a Super Nintendo emulator which allows you to play your favorite oldschool SNES games on your video gaming console.

Please do understand there are two different SNES9X emulators for the Wii/GC. This one is based on v1.43 of SNES9X for the PC and features faster game play, but lacks some features found in v1.51.

What’s New?
– Add SD card subdirectory browsing:
+ Set the cursor over [..] and push A button to browse.
– Modified controls when going into the rom selection menu (DVD or SDCARD): [ala eke-eke style]
+ Use B to quit selection list.
+ Use L/R triggrers or Pad Left/Right to go down/up one full page.
– Some menu rearrangment and a little of sourcecode cleanup:
+ Everytime you pressed B button on any option, playgame started, not anymore until you select Play Game option.
