I'm currently 6.60 PRO-C on my PSP 2001 and I've been attempting to install some .iso's for a while now but to no avail. I do have them in "Root > ISO" and I've made sure all of my .iso files are for PSP. I've attempted to reformat my memory card and restore the files, but that also didn't seem to work. Also, I do have the Category Lite plugin, so I'm not sure if that may be interfering with where the destination folder should be. Help would be much appreciated! Thanks in advance.
