    You must of extracted the ISO then.
    winRAR make's ISO associated with the software, so you must of thought it was a RAR file.

    If you don't like it, download imgburn (etc.) so you know between ISO and .rar and won't make the same mistake again [​IMG]

    There's an easier way. From any explorer window press alt > tools > folder options... > View > Show and UNTICK "Hide extensions for known file types". That way you can always see the file extension of any file.

    Maybe it won't play because you have low firmware?

    Do this for me. Right click > Properties and screenshot.
    I think that will tell you if its an ISO or not, I'm not 100% sure because I haven't done it myself.


    nvm, thanks dirty_harry [​IMG]

    no problems.


    wrighty, what did you download and what is the filename? That way we can figure out if you downloaded an ISO or if you downloaded some ancient old format.

    If the file you downloaded has the extension of .ISO, then you don't need to extract any more. Just pop that into the ISO folder on your memory card and you're good to go.

    Recompile the files to an ISO with UMDGen.

    If you get an eboot then you extracted the file too much or actually extracted the iso file. As other said, if you installed winrar with default options, then you asociated ISO files to appear as compressed files.

    i think like you guys are saying i could be getting this sort of thing because the download is the iso...so when i extract it in win-zip it would give us these two folders which make up the iso/cso file...so what i have done grabbed the zip file and compressed it to a cso file to give us a cso new file....for this method sometimes it works and sometimes it doesnt....games i found it with MOD1/F109/motorstorm acrtic edge/assasin creed bloodiness/..................maddenNFL10-which i got working with power iso and F109....i did try the umdburner too but didnt get joy with that either??????????


    i think iam basicly getting the iso as a win file and not iso....

    You're confusing yourself. Almost all sources i have found offer files as a series of .rar files. After you extract that you get a single iso. If you enable the viewing of file extensions like i described earlier, you will clearly see the .iso file. It's really quite simple mate.

    You can use a program called UMDGEN 4 to sort out all your PSP iso/cso needs. Really is a good program, it'll let you pop all of those files straight into an iso or even cso as well.
