Thanks agian for the help guys. I tried all "MiK546" says, the zipped files agree with then "rc" files, for example in "neodrift.zip" or "mslug.zip",i tried with a lot of roms... I put the command line with many games, and all says problem with the rom. I downloader the mame emulator, in this emulator the roms show, but i have this error "The selected game is missing one or more requiere ROM or CHD images. Please select a different game". I tried in xgnegeo too and the roms dont show. Tomorrow i will try with restart all the gngeo aplications.. im crazy guys, i dont know what to do
