I wonder why are you all so Thrilled
this all ready exist it called "PSP Double Expand Memory Convertor"
here is the link

http://www.superufo.com/product_html/SONY_PSP_PSP_Double_Expand_Memory_Convertor.html?aff_id=24

is not the same?

The Double Memory Converter doesn't work with SDHC cards so the best you can get with that is 2x4gb cards to get 8gb.

yes i know i already mod my post

great job

FaT3oYCG · « **Reply #33 on:** January 24, 2008, 02:07:56 PM »

do you think that there would be any way to fit this in the psp internally by removing the normal memory card slot or would that then not be able to read mspd cards - either way it could be put inside the psp and just slot the ms reader where the umd drive is then because it is a flat wire and small enough you could keep the umd drive

p.s. extremely nice mod well done

hi again

in the moment I'm just sitting in front of my psp parts and wonder where to put the sd-card-slot...
Well, of course we can replace the normal ms pro duo slot. put I want to have ms pro duo support... so that's not an option. Well, maybe if I can get a multi card reader slot thing or kind of, so I can insert either sd or ms.

Well, I gonna try some things and hope I don't screw it up

I was just looking at your pictures and it looks like you wired 1 - 8 from the microsd adapter to 1-9 on the sd reader, minus the extra ground. Is that right?

FaT3oYCG · « **Reply #36 on:** January 24, 2008, 02:53:56 PM »

yes it is that is what he said it has an extra ground pin so wire the grounds together it is quite easy to see from the picture

also relating to this which i got shown the other day

aliander · « **Reply #37 on:** January 24, 2008, 02:55:18 PM »

yes, as I said it's quite straight forward, I think I post a table here...

Function	micro SD	SD/SD HC

Dat2	1	1
CD/Dat3	2	2
CMD	3	3
Vdd	4	5
Clk	5	6
Vss	6	4,7
Dat0	7	8
Dat1	8	9

Well, I do number the pins just straigt from left to right. I tell this, cause I found some different numbering on different sheets. Often the 1st pin on the SD Card is mentioned as last (9th) one - maybe cause it is set back or something...

good luck!

FaT3oYCG · « **Reply #38 on:** January 24, 2008, 02:58:35 PM »

also i have 16gb of storage but it is in 4gb sections lol

oh ali to make it easier to understand i want to make an image for him but you have named the pins differently could you please tell me which pin links to which by using the table i posted and the pin relating to the adapter

e.g. 2 on the mem stick slot is bus state could you label the pins on the adapter the same way left to right please thanks

Could we get a pic with the numbers on them would be most helpful
Great mod by the Way

aliander · « **Reply #40 on:** January 24, 2008, 04:46:46 PM »

Just look at this page: http://pinouts.ru/Memory/sdcard_pinout.shtml

But remember, that for simplicity I have given a non standard numbering method. They count it like 9,1,2,3,4... So watch out for this. But else I see no problems

so according to this table would the pic be correct??

The contacts of micro sd would be facing up in the pro duo adapter and the sdhc would be facing down in the card reader. So for the adapter you need to reverse the order.

thanks so on the adapter 8 would 1, 7 would 2, 6 would be 3 etc..

I'll search for better pics ...

im so trying this luckily i have a friend who has a transcend laying around

JTC · « **Reply #46 on:** January 24, 2008, 06:45:21 PM »

Thanks for the help guys i think i got it now here's wat i understand can some confirm this is right

gawl47 · « **Reply #47 on:** January 24, 2008, 07:34:17 PM »

How did you get the adapter open, an exacto knife?

Also I found out that some of the 16gb sdhc cards format to around 14.6gb.

stankbot · « **Reply #48 on:** January 24, 2008, 08:22:17 PM »

I had a question...does this work with all usb to sd card readers? Because I saw the hama one that you have and it says it is a mmc and sd, but what about sdhc or do all sd readers support the format?

aliander · « **Reply #49 on:** January 24, 2008, 09:05:22 PM »

good morning guys

@gawl47:

yes. carefully cut it open. But this was surprisingly easy, cause it was mostly just stick together than really glued...

thanks for the formatting info.
I wonder why this is. Formatting shouldn't really depend on the hardware, but on the filesystem structure I put onto it - and there nearly 2gb of 16gb is pretty much.

@stankbot:
the cardreader just have to be cheap and should eat sd cards. you don't need any reading ability of the reader itself. you only use the sd slot with its connection pins.

Ali

aliander · « **Reply #50 on:** January 25, 2008, 07:15:56 AM »

hi again!

I managed to get an card reader supporting ms pro duo and so i tested the speed of the adapter build thing without psp

Here we go:

1. Transcend 16gb SD HC Card: ~16MB/sec
2. Adapter + Transcend SD HC: 8-9MB/sec
3. Adapter + Transcend SD HC + PSP: 3-4MB/sec

As we see the adapter itself (most likely the chip doing the signal translating stuff) speeds down to a half of the speed (what is also just really :censored:ing fast!), but the psp itself just seems to nibble down the whole thing...

so if we want higher transfer rates I think we have to go through usb - *wink to pvp*

also I have to mention, that I didn't found a good place to fit a sd slot inside the psp... I'm happily receiving ideas concerning this issue.
I thought of putting it between umd case and backplate - case it just takes about 3 mm in height I thought it would possibly fit. But wasn't the case.
So another idea would be to manipulate a UMD itself to get it working as a shelf for the sd slot and stuff... that sounds like fun

The big disadvantage is just that you can't use UMD while using your sd card... and that is bad when you want some isos loaded that simply only work with umd in.
So... there also is space left just under the screen on the right bottom. But we would have to insert it vertically, so direct card inserting wouldn't be possible.

so far from me
bye
Ali

really love all the progress updates ali, keep it up

wrcsti · « **Reply #52 on:** January 25, 2008, 03:20:46 PM »

wait, you have a SD micro to mspro duo adaptor, why not use that one?

JTC · « **Reply #53 on:** January 25, 2008, 05:00:02 PM »

With the Sd card reader do u just remove everything except for the actually reader part
loving this mod can't wait till my parts arrive

Here this might help some of U guys:

aliander · « **Reply #55 on:** January 26, 2008, 05:28:17 AM »

hi guys

First: Thanks

I just kicked out the multi card reader from my laptop

This one can also read ms duo and sd cards. So maybe this is a solution (yes, ok... kinda obvious

)
Put this one in instead of the standard ms slot and you can read sd cards and ms pro duo (there is mostly an adapter to ms duo in ms pro duo packages) with it.

Only have to figure out if it isn't to big. Cause it needs way more space than the standard slot...

bye then
Ali

thanks for that ali this is a really good mod well done again

hi there again!

So, the memory card reader from my laptop is too oversized to fit into the place of the standard ms pro duo slot of the psp. So well, I've a new idea, but I don't think I'll do this, cause the chance is high to ruin my ms pro duo slot

here is the idea:

stock the standard slot up for about 1mm. then put sd pins on the bottom of the slot end. so if you put in a card upwise it will connect to sd and the other way round (the way you always put in your ms pro duo) it will connect to the std. ms pins.
but most likely I'll

this up

so I'm kinda fighting with myself if I just do it, or if I should just make a nice attachment to the back of the psp and wire it internal + switch, so no need to swap card and adapter anymore...

bye
Ali
