* Fixed GameTDB * Fixed cover colors the right way * Added GameTDB support to Gamecube game headers * Fixed a bug were gameconfig in COVERFLOW_USB only showed 1 config page after gameconfig in COVERFLOW_DML was entered * Fixed text label for Video modus in DML gameconfig * Some other minor bug fixes, cleanups and changes to gain more stability NOTE: However FIX94 reverted some changes they shouldn't make you can see most changes I made for now are minor changes. I'll have to check more, but so far great job guys!
