doesn't work on 1.51
games still launch, but trying to view another photo ON THE MEM STICK after trying exploit says "image cannot be displayed" and crashes XMB when pushing O to go back. if music is playing, it still continues to bump, so it doesn't create a total system failure -- a good sign.
same thing happens via remote play, but locks up in "remote play in session" screen instead (on tv), psp just gets disconnected
