the chart is or really outdated about usbloader gx or i remember it different. ever since dios mios support, there is fan art possible, custom banners for all games, homebrew, so there is ah, some sort of emulator plugin option. if needed, full emulator options could be done (doesn't take that long just extension recognition and starting through the right installed emulator). ios automaticely + manual selection, i don't know about nand selection if you mean sneek, it can handle it. boot animations fully work. ww and vc compatiblity are your systems fault, if it works on system channel it'll work in usb loader for what i've tested so far.
