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?
