is a wad just a pointer to an application? i'm confused because i installed a wad for usb loader 1.5 in sd:/apps/usbloader and then replaced the boot.dol in sd:/apps/usbloader with usb loader gx and the channel still works fine (it points to usb loader gx now). i thought wad's contained all the information to run the app without having to use the SD card. EDIT: hmm...now that i think about it i installed a forwarder using the wad tool. so i guess i would need the SD card in if it's just a forwarder. is that right?
