overjoy.psm 6e4f75359b * Fixed cache (again)
* 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!
