usbloadergx/source/libwiigui/gui_gamecarousel.cpp
dimok321 1d2854c777 *Fixed issue 1808 
*Fixed issue with crashing carousel when switching from empty game list to none empty list.
*Added download for Full HQ & LQ Covers. When both are checked HQ Covers are prioritized.
*Added support for Full HQ & LQ Covers:
Full covers are currently used only in the GameInfo Screen (Press 2). The Box can be rotated in there with the Nunchuck. When the box is clicked it will jump to the midlle of the screen. Here it can be rotated with Nunchuck & Wiimote D-Pad. Also it can be zoomed in/out with the PLUS or MINUS buttons. Zoomed in covers are currently cut off when going too far into the screen because the axis had to be layed to the middle to keep the symmetry. Don't report issues about that. It's known. Another use of full covers might follow with a new layout if we think of something nice ;).
*Added support for different box colors. Box colors are taken from WiiTDB so if you get a wrong color complain at WiiTDB :P.
