This is an answer I got from a forum member here to my question: can I use micro SD cards into memory pro duo cards? You could buy an SD adapter for the PS2, there are numerous available, some even with twin-slots, however nobody can guarantee their seemless operation. MSPD is always the recommended storage device, however adapters are cheap enough, so you could try one out. Since it was a side question on the other topic I think it deserves it's own topic. So how/where are you able to get these adapters ( i live in europe/Netherlands)? Also Can the psp use my 32 GB microsd card with it? I don't know if any memory limit?
