As we know, pin 9 of the MSPD is the VCC pin. I've wired up 2gb internally, pin for pin, with a 2 way switch on pin 9. Switching it one way connects internal to the power supply, switching it the other way switches the swappable memory. However, neither memory stick is recognised by the PSP. I'm certain I have a bad connection on pin 9, but do any of you gentlemen (or RA1N) think it might be something else?
