Use a Pro Duo Memory Stick in a Regular Duo Adapter

In my laptop I have a small adapter on the side of it. It supports SD, DUO, and some other one that I'm too lazy to find out.

Well in the extreme case that my PSP was bricked and I needed a memstick I decided to use it.
Little did I know that it would get stuck and I would spend 30 min fishing it out.

So another day I decided to improvise and use some common office tools.
TAPE AND A PAPER CLIP

To begin get out a paper clip and put on the bottom of the memstick

Put the paper clip along the center of the bottom

Tape it down securely.
The method I used was to tape it down across the top of the memstick to
bind it to the card and them lengthwise of the paper clip to secure it more.

Now just test it to make sure that it won't fall apart.
Then just slide it in.

Works like a charm.
Keep in mind that it will still register as a DUO on the computer.
