I am not sure about memory cards being region locked, but I can tell you that for the most part, saved games are. Each game is given a unique ID and these vary for the same game between release regions and even just editions in some cases. It is this unique ID that the saved games are stamped with that associate them to that game. As far as one region game is consider, those saved files from another region are from a completely unrelated game.
My guitar teacher taught me the best way to coil the cables for electric guitar and amplifier cables (any tear in the inner copper wiring can create artifacts in the sound) so i use it all the time now, on any type of cable.
For starters I need to point out that any wire has a natural resting position, colied at a specific arc. That's because the materials used in them have a resistance against being bent (kind of like a spring, or car tire if pressed while sitting upwards).
Your goal is to wind the wire so that the actual coil is not too tight and strain the isolation or the inside conductor wire.
The PS2 has a really small radius around the middle and most probably, you force it to that radius and bend it to an arc that is smaller than optimal until the rubber gets old and eventually gets cut via strain.
Also you need to be careful not to twist the cable around it's axis. Inside, the conductive wiring is fairly sensitive even if the material is flexible.
That being said, let's wind the cable:
- Cable wire in one hand (preferably close to one end) and wire (at a resonable distance from hand A, you'll see why) in the other hand (let's call them hand A and B)
- Start twisting the cable gently with the tips of your fingers in hand B while holding the other end in hand A. Notice the cable producing a slight coil according to your twisting motion and that the cable "wants" to get closer to the point you hold the cable in hand A. Don't force the cable into the hand A. You need to find it's natural resting arc.
- The wire will coil itself and produce a round circle, the coil, that you can hold with hand A. Now you have one coil that is held by hand A while hand B has more wire to wind. The size of the coils should vary depending on the thickness of the cables.
- Keep doing it until you have a neat bundle of coils that you hold in hand A.
- Provided you've wound it nicely, you should not feel a big resistance at the middle of the coil bundle if you'd be to tie them together with a piece of wire right in the middle part, so that you flatten the coils into a ribbon like bundle. Alternately, only tie one side of the coil bundle, but the coils might fall apart and unwind and you'd have to do it again.
As far as controllers go, never coil the wire on the controller, it's too tight and it's always straining them, hence the problems.
Also, don't coil the wires on the analog sticks. Their springs aren't supposed to resist a wire wound around them.
You can coil it this way that I just explained "around" the PS2 controller, just keep in mind, you can't wind the part that goes into the controller, it may break because of the way the wire is inserted into the plastic case.
In my experience, the controller cables are annoying, but coiling them ON the actual device is always problematic. I'd say keep them under the actual controller with the tying knot on only one coil side.
Keep in mind, never strain the wires, they know what they want.
I am sorry, I cannot provide any photos at this time and I hope this was descriptive enough.
