Oddly enough, back in the PSP1000/2000 era, I had acquired a 2GB Sony Memory Stick Duo, literally bent in the middle about 45⁰ or so similar to the bend angle in the post photo.

The friend that gave it to me knew it couldn't fit in his PSP bent like that, and neither of us expected it to work, so he just donated it for my junk parts bin.

Well, I decided to just try bending it back flat, and believe it or not, it worked just fine! I used it for like 3 years to install custom firmware and homebrew on a number of PSPs back in the day.
