Despite the language barrier, I can tell a good app no matter what. A Brazilian developer, Luiz Pestana, has just released an excellent FTP app based on Zx-81’s PSPFTP. But here’s the thing, this version was developed for use on the OE firmwares, taking advantage of the higher firmware’s WiFi security. This kind of App is also perfect if you've lost or cannot find a USB cable for your PSP! Note that you must place it in the normal GAME folder, not GAME150 like any other homebrew. Great job Luiz, we hope to see farther updates to your new homebrew!
