B/1 buttons now trigger the Cancel/No button on 2-button WindowPrompts, and the button on 1-button ones.
Added a 1+2+Plus combo to the Menu Toggle options alongside L+R+Start, to eliminate the possibility of a user getting locked out of accessing the menu if they set L+R+Start while using a Wiimote (credit to Niuus of Snes9xRX for the idea).
An option to mute game audio was added to the Audio Settings menu (adapted from Tanooki16's implementation in Snes9xTX)
Minor updates to some text strings for consistency/capitalization. The most noteworthy change is renaming the "Original" rendering option to "Original (240p)" - this was done in response to some confusion in CRT gaming forums as to how to enable 240p mode within the GX emulators (even if it's technically 224p here, 240p is the common terminology for what they're looking for).
