Hmm... Maybe it's a good way to do it :) Find [or make] a patch which is changing ifs/settings/camera to card/camera. Download Gslide. Make a main file adding patch [remember 'bout good header] and use XS++ to load main to Your's W810 ;)

PS. I don't know will that work - I haven'r got W810 and I don;t know. You must only try ;)
