USB Loader GX Release V2.2 New: - Added game categories and filter games list by categories (Can be imported from WiiTDB). - Wiinertag support. - Supporting arguments from meta.xml on boot (--ios=xxx and --usbport=x) (Requires Homebrew Channel 1.0.7+ or UNEO Forwarder v3.0). - New ehci modules by Rodries with better drive compatibility. - Added two new video modes to force progressive video mode, 'FORCE PAL480p' and 'FORCE NTSC480p'. - Added Sneek Video Patch mode. - Added new 'Inherit' setting for game settings named "Use global". If that option is set then the main loader setting is used. - Full d2x cIOS support with it's new features (Block IOS Reload, Return To, Sector Sizes > 512). - Support for sector sizes > 512B with FAT32/NTFS (Requires d2x v6+) - Real support for simultanious use of both USB ports without switching the 2nd drive temporary off. (Requires Hermes cIOS or Rodries MOD of the Hermes cIOS (recommended)) - Added two new settings menus - Added saving of game browser position when returning to USB Loader GX Changes: - Improved several GUI controls/navigations - Changed settings menu layout and sorted the items to their correct place (HDD menu, features menu) - Set games settings to use the global setting by default, set to "use global" to use the main loader settings. - Use TinyXML instead of MXML (better XML support) - Updated to new libs (libogc, libfat, libext2fs, libntfs) Fix: - "Return to" option now work for all games, even problematic games like Prince of Persia. (Requires d2x v4+) - Xflip setting fixed. - Fix the parental lock of Individual game settings (Thanks to NJ7) - Fix Theme downloader - Fixed reset of the loader when loading game with IOS reload and disabled WiiTDB titles - Fixed timeout timer on startup to count correctly. - Fixed reversed disc image download when Custom/Original option is selected - Fixed reload of game list after a game rename - Fixed horizontal text scrolling - Fixed booting games by arguments (headless id feature) - Fixed We Dare game boot (thx oggzee) R1099 Change Log: *Added IOS225 from Rodries cIOS Installer MOD to Hermes IOS types New Forwarder V3.0 Changes: *added support for ext partitions *added support for arguments from xml *clean up of source
