 // Who  When        What
 // ---  ----------  -------------------------------------------------------------
 // JLH  12/23/2009  Created this file
 // JLH  12/20/2010  Added settings, menus & toolbars
+// JLH  07/05/2011  Added CD BIOS functionality to GUI
 //
 
 // FIXED:
 //
+// - Add dbl click/enter to select in cart list, ESC to dimiss [DONE]
+// - Autoscan/autoload all available BIOS from 'software' folder [DONE]
+// - Add 1 key jumping in cartridge list (press 'R', jumps to carts starting with 'R', etc) [DONE]
+// - Controller configuration [DONE]
 //
 // STILL TO BE DONE:
 //
+// - Remove SDL dependencies (sound, mainly) from Jaguar core lib
+// - Fix inconsistency with trailing slashes in paths (eeproms needs one, software doesn't)
