Why are all the PSP ISO files corrupted??

[c0dawkd]

I have been trying to get several ISO files for my PSP emulator but nothing seems to work. I was able to get one game to work but any others, once i unzip them using 7zip, they say the file is corrupt and freezes up my 7zip program. I would love to become a premium member here but I am not going to invest my money in files that work when they want too. If anyone can help me in understanding or may be able to point out something that I am doing wrong would be greatly appreciated! I have also tried to attach a screenshot but this site will not let me =\

I've seen somebody else complaining about this. Supposedly it clears up if you use download managers. I don't know anything myself though, I've never had any issues
