Genesis Plus is a Genesis/Megadrive emulator, ported over to the GameCube.

Changes:
– added DVD automount: automatically call libogc DVD_Mount function if ISO PVD reading failed (idea taken from softdev’s last neocdredux release). This may be useful for loading roms from a DVD after booting from SDLOAD or after stopping DVD motor.
– added “DVD motor off” feature, like in others emulators
– corrected Memory Card mounting function: EXI_ProbeReset() function was never called if the first mounting attempt failed. Should fix some of the “Unable to mount memory card” errors.
