I'm having problems with my homebrew apps. They used to work fine, but all of a sudden they do not work anymore. I start it up and they all freeze. I didn't update or anything. My firmware is 5.00 M33-6. My MS games still work, just the homebrew apps don't. I did do something, but I don't know if this affected it. I signed up for PSN and logged in, but it said I couldn't access it because I didn't have the right firmware. That's the only thing I've done that affected the homebrew. I didn't do anything else. My homebrew apps include PSPTube, MAME4ALL, gpSPMod, CPS2, SNES9XTYL, Netfront Browser, and Fusa Gamepad. None of these apps work.
