-Classic (non-tabbed) selection menu now consolidates GB/GBC/GBA roms into one list
-Rom paths are now cached after viewing the first time on boot, so switching between tabs/returning to the game selection menu should be quicker
-Frameskip option has been added to "video settings" during gameplay (1, 2, 3, off)
-Added sharp bilinear filter
-GB/GBC audio improvements
Fixed a broadband audio noise floor present in the GB/GBC audio pipeline (introduced by the resampler's default interpolation mode); switched to a higher-quality interpolator for the core-to-output sample rate conversion, reducing the noise floor by ~17dB with no other pipeline changes.
-Save states now have their own directory (default is mgbagx/states)
If you have any save states in the old directory you need to move them to the new one
-Improved how the UI handles settings window (i.e. GB Screen Zoom) when using a Gamecube/Classic Controller
