Dude, this is awesome.
Keep it up man. It'd be awesome for any PSP to use SD cards.
Hope you get it done and get a tut up.

How would I wire the memstick reader to a sd reader (see pic below).... since there are 9 pins on the sd card and 10 on the psp memstick how would I wire it...

So hi guys

I don't think that there will be a step to step tutorial - except another one will make it - because this forum thread, based on the simplicity of the mod, automatically some kind of tutorial. You just don't have anough steps to put up a tutorial.
Get a SD Slot (Memcard Reader), an microSD->MS Pro Duo Adapter and solder it. That's it, guys.

Well, when you don't in what relation the microSD and SD Card pinouts are... well, this have been well pointed out during this thread. Just read it!

bye
Ali

Anyone?!? PLZ

@redryno:

This is the aim of this mod -> to link an sd card slot with the ms pro duo slot (psp).

you can't just wire it up, because sd cards and memory sticks have other conversation protocols. that's why you need that kind of adapter I used (microSD -> memory stick pro duo)
now you can wire the micro sd to the sd card slot and put the memory stick adapter into the memory stick slot -> voila

just read through the whole thread before doing double posting of already answered questions, thx

that's nice

but the speed of 4mb/sec or more probably less than that is kinda frustrating...
well, it is fast enough for isos and videos... so here you go

I forgot to tell you, that this will also suck your battery to death...
that was one kind of reason, why I decided to use SD cards...

Sorry man, but that won't work. That will make your sd card accessible through the ide, turning it into a bootable harddrive. It won't work the other way around. If you tried to attach it to the sd=>pro duo it would think that the PSP is a storage device if it even registered.

has anyone tried any multi-readers yet?

Cause i have a project im working on and i would NOT mind the size of a multi-reader if it worked

brentbizzle · « **Reply #70 on:** February 01, 2008, 08:23:42 AM »

I think a multi-reader would be too big to place in the stock spot... but you could probably mount a multi reader in the UMD area and wire it to the board.

I was toying around with the idea of using this one http://www.newegg.com/Product/Product.aspx?Item=N82E16820162018. It's small and reads SDHC and Pro Duo (with the adapter). I'm guessing you still will need the microSD to Pro Duo adapter.

aliander · « **Reply #73 on:** February 02, 2008, 04:52:31 AM »

hi there!

I have on doing SD/SDHC and MS Duo. Was about to use it internal, but it was way to big...

But anyway it would be no problem to use. Just wire up the stuff it should be and for Cards using other conversation protocols (like sd->ms) use an adapter (like microSD->ms pro duo we used in this mod)

After looking at some pinouts of the MS and SD, I really don't think that a multi-card reader would work, well you wouldn't be able to use MS cards in it only SD. From what I understand of this mod the reader is only used to be able to connect a sd card to the ribbon cable, it is not actually doing anything as far as read/write conversion. The microSD to MS Pro Duo is what is actually doing all the work. If you tried to put an MS into a multi-reader wired like this mod it would be trying to read it as though it was an SD, becuase or the MicroSD to MS Pro Duo adapter.

aliander · « **Reply #75 on:** February 02, 2008, 09:49:59 AM »

yes, exactly

but you can do wire up an multi card reader and put up some adapters to ms pro duo, so you can feed it with more cards.
so you'll have to go something like this: hama bridge card -> sd card -> microSD -> msproduo
kinda bad concept, but I don't see an easier way. that way it's kinda lego playing

cyloh · « **Reply #76 on:** February 02, 2008, 08:31:01 PM »

Great mod aliander,

Getting my parts together for this. Just a couple of questions.
On the SD part, there are 2 grounds, so I just connect them together?
If so, where does the ground on the MS adapter connect to?

Sorry,that I don't know much, but if the SD card reader is only used
to hold the SD card and does not help in processing, then in theory
we could just solder the cable right at the SDHC card pins?

Thanks

JefeSand · « **Reply #77 on:** February 02, 2008, 09:09:35 PM »

Sorry if I step on your toes here aliander, I'm sitting at work bored so I figured I would field this question

Aliander has Pins 4 and 7 on the reader connected and then there is a wire going to Pin 6 on the MicroSD to Pro Duo adapter from Pin 7 on the reader or he has it in a Y configuration (I can't really tell). So 4 and 7 on the reader are connected to Pin 6 on the MicroSD to Pro Duo adapter.

And you are absolutely right about being able to solder directly to the card however becareful if you atempt it. The heat could posibly damage the memory card.

cyloh · « **Reply #78 on:** February 02, 2008, 09:20:11 PM »

Haha same here JeFeSand, bored at work too.

Well thanks for the info so far. I guess we need to find out from
aliander if its a Y configuration on the grounding before I commit
to this little good mod. Cause in his pictures, all I see at the SD
end was ground = ground connected.

Owh, about the slow speeds on read/write, could it be due to the
3.80 firmware? Heard dark alex saying it was a bad part on Sony.

aliander · « **Reply #79 on:** February 03, 2008, 06:54:30 PM »

hi guys

yes, you can solder this directly to a sd card, but of course you will lose card-change functionality and risk your sd card (as mentioned) caused by heat damage.

And to your other question:
well, have a look at the pinouts on the 2nd page of this thread.
as microSD has 8 pins and sd card has 9 pins I had to look for the difference. in this case it was quite easy as the only difference was a additional ground connector on the sd card. so I just had to bridge it.

I don't see a difference between bridging to pins (1-2->3)and making an "Y"-Connection (1->2-3). all would be connected to the some node, so no difference...

maybe I misunderstood you

That's because they count it as multiples of ten for advertising purposes, and format it in a completely different way.

Slimby

Sort of. I'll explain in a little more detail. It's base2 (binary) trying to fit it in a base10 world. 1024 is 2^10 in binary and becuase it is close to 1000 in base10 the powers that be named it a Kilo. So a Kilobyte is 1024 bytes. From there it gets even crazier. To get a Mega- (in SI format) you multiply a Kilo by 1000 but wait in our base2 naming convention a Kilo is 1024. So a MegaByte is actaully 1024 x 1024 or 1048576. A GigaByte is 1073741824 (Megabyte x 1024). Now lets make it all come together. Multiply 14.9 x 1073741824 and you get 15998753177.6 bytes. Now round that up you get 16,000,000,000 or 16 giga (Si Standard for 1 billion). Do you see where I'm going with this? As far as advertising goes they usually round the bytes to the nearest mega or giga and then use the SI naming convention based on kilo being 1000. So you are actually are getting about what they advertise it's just in the computer world a kilo mean 1024. Meaning to turn 16000000000 bytes into GB you have to divide by 1073741824 which equals about 14.9GB.

Has anyone tried porting usbhost to the iphone or i pod touch because people can make them do whatever they want? That would be nice. The i pod touch holds what 16 or 32 gigs max?

cyloh · « **Reply #89 on:** February 06, 2008, 05:28:47 AM »

I think having an Ipod attached or internal modded is a burden. You'd
have to charge it or have some power source ( via PSP or external )
attached to it.

Back on topic, just ordered the micro SD -> ms adapter. non-branded
china type.

If it works out, i'm going to have something like this :

SDHC -> micro sd/ms adapter -> switch -> PSP ms slot
MS pro duo -> switch -> PSP ms slot

Means I'll gonna do this internal, having 2 card reader slots at the UMD
side ( dumping the use of UMD ) have those two wired to a switch and
then leading to permanent soldering at the PSP ms slot.
