I have a PSP v1.5 and I have UMD Emu on it. I have downloaded a few games but can't load any of them. I don't see an ISO file in any of these games also. When I extraxt the files of the game i downloaded onto my desktop this is what i see

a folder named: PSP_Game and a UMD_data BIN File

when I click on PSP_Game folder, this is what I see

.xvpics folder, SYSDIR folder, USDIR folder, ICONO.PNG file, ICON1.PMF file, PARAM.SFO file

And inside the ablove folders i have named there are other files....bottomeline, am I downloading the wrong files to play on my PSP?? Shouldn't there be an ISO file somewhere...well like i mentioned I have checked in all the folders and sub-folders..NO ISO file.. Please help me out, can I still play these games I have downloaded?? Thanks

r u sure they r ISO extension?
they should b in the ISO folder in the root directory

You have to make it an iso image by using UMDGen or Vcdrom. Somebody extracted the iso so that is why you see all these seperate folders.

you have probably downloaded homebrew games not iso's
