I'm not sure how he did it but you can use a Dip switch and solder the ground of the Memory stick slot to the switch and flick to to switch between

no dip switches are off/on not on/on and its not that simple thats why will had to use the ic's

well im not trying to make mine like his, his will hold 2 sticks at the same time and switch between them i just want mine to recognise and read 1 of the 2 i know that without the ic's its imposible to simply put a switch on the ground to switch between them because all the other pins comunicateing . I dont understand  is there a switch in the slot that tells the psp that a mem card is in? if so how do i trigger it without a physical card in the slot?

There's a pin on the Memory Card slot that tells if its inserted, Its pin 6. I must either make a connection or communicate with the memory card. Pin 6 is also connected to pin 10

have you tested it? so ur saying if i wire a switch between pin 6 and 10 and dont put a mspd in slot and wire my sd to produo adapter to the produo slot then when i flip switch psp will read the sd card?
