I have a hacked Slim and 6 Pro Duo Cards for it, 4 16 gig, 1 8 gig and 1 4 gig. I can only fit 3 inside a little, resealable bag and put it into the UMD slot, but even then it takes some effort to fit it so i can close the UMD slot opening. Id like to fit the other 2 cards so i can take them with me all the time and ive literally never used the UMD slot on the system. Can i take apart the PSP, remove the UMD slot and still have everything work ok? Would really make it easy to hold as many cards as i like with me, and perhaps some spare batterys as well. Thanks.
