it is possible but you have to buy one of these:
http://www.mod-chip.com/en/psp_double_expand_memory_converter.php
but it doesnt support mmc pro duo but interesting how it can bond two sds/mini sds/normal mmc to act as one...Ive got one works fine upto 4gb each card. (some 8gb sd's work but hard to find as most are sdhc and that's not supported)

This mod is a very hard one to pull off. i've tried and failed. if this is your first mod i'd start on something easier like the led mod or usb charge. just to get a good understanding of where everything is. you have to solder wires from the MS port pins to the adapter (the one above would work), however it's alot of work and there's more chance of messing up the connectors the ms port.

Go here for info http://bepsp.com/Parallel_Memory_Mod.html (http://bepsp.com/Parallel_Memory_Mod.html)

If you pull it off let us know! good luck!  :tup:

-edit-

Damn, beaten to it. need to be quicker, lol! :)

screw the double expand huge bulky ugly 4 gig limit its useless definitly not the cutting edge in memory mods why not just do the sd mod and swap the cards when you need to or better yet buy a 16 or 32 gig sd so u never have to swap them

Post by: blaze3927 on July 06, 2008, 02:34:16 AM

well for a 8gb + sd ...you'll have to get an sdhc to mmc converter cos I'm not too sure that 8gb sd(non hc) exist

could you not just solder wires from the pins on the memory stick to the corresponding ones in the psp?

I had it working and it is not worth the effort.

To give you an idea of the complexity of the project.

Here is 1/10 of the circuit


(https://acidmods.com/forum/proxy.php?request=http%3A%2F%2Fmysite.verizon.net%2Frestxsa0%2Fxi-cpld-004-lg.gif&hash=4c977362f234072eb514d3d5f8b1820155eaf2a8)


All this was so the PSP would see the second stick when the switch was changed


SD1 is memory stick one and SD2 is memory stick two. The other side is where it plugs into the original memory socket.

The circuit all fits inside one chip. A 100,000 transistor CPLD custom gate array.

The chip is not expensive about three dollars.

You have to have a fast pc.
Gate array design software.
Emulation system to test
Jtag device to program the gate array
Soldering skills for a 64 pin surface mount chip

I designed it ran it on a simulator software to make sure it worked and then someone came out with a
SDHC card to pro duo adapter which I got from DealExtreme for $6.50 and another company is releasing
a dual SDHC card to pro duo adapter allowing you to run two 16 gig SDHC cards and no switches.

Your time has to be worth something. If you are doing it to learn something valuable then go ahead.

I am not trying to tell you how to spend your time.

Just saying been there done that and most people have no idea how complex it is.
