Memory Card Issue

[gtsamour]

I would fix the original memory card in your place and maybe buy a 3rd party one if I needed the more space.

Here's my original memory card after replacing the battery (CR2016) and before closing it up with double sided tape.

Bump.

Hardware fault found in Unibios 4.0 on my Official Memory Card. I assume the battery is dead.

Is there a trick to getting these open? Or is it just use a pen knife to carefully prise it open, then pop in a new battery and some double sided tape and go?
