usbloadergx/source/libwiigui/gui_gamecarousel.cpp
dimok321 8bec876889 *Removed ramdisk 
*Lot's of changes in image processing
*Added use of libgd and ImageData class from WiiXplorer. No more crashes with corrupted images and no more restriction to images sizes that are devidable by 4 :).
*Added a recource file manager for better access of all files/images for internal files and theme files. Some themes will have to adjust some filenames because we want to use the same filenames for themes and internal source files.
