PPSSPP not showing folder of ISOs

[fivefeet8]

There should be some options when you load PPSSPP. The top menu should show "Recent | Games | Homebrew & Demos". Touch on "Games", then you should see some browsing options. It should show the current path/directory it's currently in and a "Home" option along with a couple of view options(Squares Lines). Touching on "Home" will bring the file browser to the main root directory of the phone internal SD Card. From there it's fairly easy to navigate to the directory you've put the game images in.
