you have to open your
own dump.bin with s1res (after you made a backup-copy), then doubleclick (/click on the plus) on "ui30.res" or something like that (in my firm it's named like that), doubleclick on "icon", search the pictures you want to replace, import the new ones (the ones from the vista-pack, you have to extract the *.zip-file with winzip or some other application like that), save the firmware and load it to your player again with the upgrade-tool. hope that helps
