- reverted change in 5.4.0 that may be the reason some users have issues loading games from sd card. especially on vWii. - changed wiinertag to riitag and cleaned up code for it. More info here - https://gbatemp.net/threads/riitag-gamertag-for-wii-replacement-for-wiinnertag-and-dutag.559500/ - removed dutag - changed optimmization from from -os to -o2 to hopefully compile better. - other minor code cleanup.
