I copied it into the location of the SNES emulator, renamed the original emulator from SNES9XW to SNES9XX and renamed the update from SNES9X to SNES9XW.
Go into the emulator screen and load up the SNES emulator, click "Show Menus" and in the "Window" menu click "Stretch Image" do not click "Full Screen".
I've just had this working spot on with Super Mario All-Stars, my Mario Kart crashed on me but I have two other ROMs to try yet too see if they work any better as well as about 1000 other games to play with so I'll let you know if it carries on performing OK!!
I know you've already posted that you solved it but thought I'd post this up so others can get it in and working if they wish with minimum hastle.
Where can i download games from?
