i just d/led few games and when i unzip the .rar there is this folder PSP_GAME and one file UMD_DATA.BIN into the PSP_GAME i cant find any .ISO or .CSO file. any idea what should i do?

I think its a dax file im not sure though...if it is then convert to iso and then cso if u want

hmm... it's not the dax file.. there is some eboot.bin and what data.bin..

ok there is an easy solution to this... you will first need to download this tool here UMDGEN 4.00 form this site here UMDGEN . Then what you will need to do is extract the PSP_GAME folder and the umd_data.bin to your desktop or wherever you feel would be best for you. then open UMDGEN and copy the PSP_GAME fodler and UMD_DATA.bin into UMDGEN..ow you will want to go to file then save as and save it as a CSO and use compression 9 for smallest compression... That Hopefully should help you if not then PM me with any troubles you have

hey man, this is not too big a problem. THe download you got is directly off the umd (using irshell you can see all the files). The files just need to be put into a iso file. It isn't too hard to do and doesn't take long to store either. If you wanna save space and turn it into a cso file that has been ripped, that is a little harder and will require some more skills and al lthat jazz.

Are you sure you extracted a ".rar" file? It sounds like you might have extracted the ".iso" file.
That can easily be done as WinRAR auto-associates itself with ".iso" files and makes them look like ".rar" files.

another program you can use to merge those two folders into an .iso file, is winace. google it.
