usbloadergx/source/libwiigui/gui_circle.cpp
dimok321 7db67e75af *Added several basic gui classes like drawing box/circle only with the GX engine without the need of a resource
*Created a checkbox class with them
*Changed the prompt window to a class
*Changed cover download to a checkbox selection of what you want to download. Changed discart download option to only switch between what is prioritized (original/customs)
*Fixed a little alignment issue of the progressbar
*Reverted the change for check disc in drive. Some drives couldn't handle it in IOS58 mode :\.
*Changed playcount from an 8 bit to a 32 bit counter (got 8bit by mistake) which limited it to 255
*a few little optimisations
