ZKL54 gave us word of a new modification for 3.10 OE-A that's useful out there for those folks who are using PopStation. USB Mod v4b for 3.10 OE-A will actually help you save on space on your memory stick by enabling you to stream files from your PC via the USB.
Notes for this version: According to the developer, this is actually an unofficial update of TheBuzzer's modification for SE-C. If you remember him, he also made a useful and rather prolific application known as the GUI DEVHOOK Launcher, so you can bet that this little modification's base programming came from a great app maker.
Of course, using this might sound like a bit of a hassle, since the main reason you probably use the PopStation is to play on the go. Despite this, USB Mod may save you a lot of trouble when it comes to accessing certain files on the fly, though we wonder just how well this would work with PopStation.
That being said, remember to check the readme for instructions so you don't muck up your PC or your PSP, grab a long USB cable, and see what magic you can make with this little app.
