it's here :
basically you :
1) use the downloader to update emustation to the latest test version (" xbmc options" from the carousel, then "downloader", then "update" then "emustation test build". )
2) do step 1 AGAIN (the second update is super small)
3) decide where you want to save the roms (press START to go to the menu in emustation, the "advanced settings", then "roms path", which I set to /F/XBMC-E/Roms and I set the media to /F/XBMC-E/media
4) FTP all the roms from resurrection extras to /F/XBMC-E/Roms/snes
5) use the downloader (" xbmc options" from the carousel, then "downloader", then "artwork", then SNES") to get all the artwork (except the movies)
6)If you really care, FTP all the movies from "/Movies" in resurrection extras to /F/XBMC-E/media/snes/videos
7) update your list of roms (press START to go to the menu in emustation, then "scanner", then "scan all systems"
you're good to go
