usbloadergx/source/usbloader/disc.c
Cyan 48b3ab3324 * Updated default Gamecube Banner URL. 
* Added an URL auto-updater for users with the old 
  GameCube banner URL.

Devolution : 
* Added forced video mode to PAL60Hz 480i when playing 
  NTSC games on a PAL console.
* Added Crop Overscan and Disc Delay settings from 
  Devolution r234 
  - For PlayLog setting, use USBLoaderGX Playlog setting.
  - "MemCard emulation on NAND" feature will not be added.

Nintendont :
* Added support for Nintendont v1.135+
* Added MemCard Emu "Multi" support, named "Enabled" like
  with Devolution (OFF > Individual > Enabled) (v1.135+)
* Added MemCard Blocks size option (v1.135+)
* Added specific game settings (Metal gear Solid)
* Changed to use Argsboot method only if AutoBoot is set.
