   8 // Who  When        What
   9 // ---  ----------  -------------------------------------------------------------
  10 // JLH  12/23/2009  Created this file
  11 // JLH  12/20/2010  Added settings, menus & toolbars
  12 // JLH  07/05/2011  Added CD BIOS functionality to GUI
  13 //
  14
  15 // FIXED:
  16 //
  17 // - Add dbl click/enter to select in cart list, ESC to dimiss [DONE]
  18 // - Autoscan/autoload all available BIOS from 'software' folder [DONE]
  19 // - Add 1 key jumping in cartridge list (press 'R', jumps to carts starting with 'R', etc) [DONE]
  20 //
  21 // STILL TO BE DONE:
  22 //
  23 // - Controller configuration
  24 // - Remove SDL dependencies (sound, mainly) from Jaguar core lib
  25 // - Fix inconsistency with trailing slashes in paths (eeproms needs one, software doesn't)
