i dont think anyone has made a skin in 1024 as most dont run there carputer at that resolution, but... you can run any skin at any res you want, you just have to change the res in the ini file
look for "frodoplayer.ini" file in the root of frodo instalation
change the width and height to 1024x768
also make sure you have use advanced functions set inside frodo settings (from within the player)
this will stretch the skin to fill whatever res your running.
