i found this not sure if it works or not, but not to sure about the site but just a heads up for all you non soldering savy people or who are too lazy you can buy one its $19 usd

and also since i never play my psp without a handle im gonan make the mod internal but in the handle not in the psp so i can still take it to schoolad use the regular memory stick, but hope eevryone can get this mod to work.

I am trying to make a mod for having two mem sticks and i am pretty sure this diagram won't work. I have tested it without any good result and now i am going in other directions. I am supposing you want to have both sticks inserted at the same time and switch between them with the switch.
If that is the case this won't work since pin INS is always grounded and psp won't be able to recognize that you have changed the stick.
If not, and you don't care to be able to have just one stick inside at the same time, you don't need the switch for anything.

hi
The first drawing is a summary of the discussion

you have to put the line 6 and 9 on a micro switch two way...

Edit:

everlasting_will · « **Reply #213 on:** March 19, 2008, 03:45:52 PM »

Well, that could work, i haven't tested that so i can't say it won't.
But you can't be sure it will work until you test it, unless you can say that a memory stick without just INS and VCC has all of its pins in a High State Impedance and i am not pretty sure of that.
If it is not in HSI (high state impedance) you can see that the lines going from the psp to the memories will find two ways ( the two sticks) and therefore you would need that the sinking-current, for example, of the DATA[0:3] were capable of supplying twice the current it supplies when only one memory stick is inserted.The same for the rest of the pins.
May be the PSP memory stick driver is capable of doing that (supply double current)but, you also need that the memory stick itself were capable of supplying more current too, as far is the DATA,SCLK, etc. from de MS to the PSP will find also two ways ( the PSP and the other memory stick/SD ) and sure this is less probable.
I could continue on saying things against doing this kind of mod that way, but you never know, may be you do this your way and it works, but that is quite difficult.
If you want to be sure that this work try eight switches

other ways until you test it and prove the opposite, these diagrams are useless.

I am looking now at the pinout of the SD on your picture, and i see that the INS pin in a SD (CD/DAT3) is also used for data. I think the one who made this mod asked before an issue with the speed, that could be a reason, you are not using that data line as far as you have to put there INS. I don't know may be looking at the protocol of an SD will help and may be it is possible to simulate an INS pin with the help of a switch and put in the CD/DAT3 pin a real data line of the psp, DATA3 for example.

utility of this kind of diagram? with this drawing, you doesn't have to read all the topic, to having an idea of the job we have to done...or what can we done to make it better.

without this kind of info, no quick reflexion...no quick suggestion.
and if you have another solution in the futur, you can do a drawing for us.

that's a great help too, for all peoples who not speaking english.

everlasting_will · « **Reply #215 on:** March 20, 2008, 08:58:39 AM »

I think you misunderstood me. I didn't pretend to bother you with my words, I just was trying to say that unless you are absolutely sure that diagram will work you should advice that although theoritically it seems right, you can't ensure it works, or you can ask people for review it.
Sure you agree with me that if you find in a forum a diagram that explains how to do something, you spend some hours doing it in your psp and then it doesn't work, you would feel disappointed with the one who posted the diagram as way of doing whatever.
I have spent many hours trying to make this mod, i think that now i am closed to finish it but i am not even sure that it will work, theoritically i think it should, but i am not sure. If i get it i will explain how to do it although i think it won't be very interesting because it is quite difficult to do it and i am not sure that having two memory sticks worth it.

So i am sorry if my words bother you, i didn't pretend to. Also i appreciate your diagrams as far as they are very clear and i am sure that you have spent time on them.
Once i have said all of this I would prefer to discuss about a real way of doing the mod, taking in count the protocols of the memories and how they work. For example, i have tried to find the voltage info of the pins ( data, sclk,etc) and i only know the voltage of the theoritical VCC ( 2,7-3,6 ) i don't even know which voltage supplies the psp by pin VSS. Also it would be very interesting to know if all the memory stick uses parallel interface to communicate the psp or only high speed memory sticks use it, and things like that.
So if you are very interested in doing this mod i invite you to start a deeper study of all the stuff necessary to make it.
Cheers

I still can't find a decent microsd to mspd....I am afriad to order another transcend from hong kong...any ideas?

*FuFa · « **Reply #217 on:** March 24, 2008, 05:34:50 PM »

Well mine sure isn't working, after some googleing I got a quick question to all the people that didn't get it to work:

What sizes were the SD cards you were testing with?

Since this post is kinda... confusing if you know what I mean
http://forums.afterdawn.com/thread_view.cfm/636290#3893655

His one doesn't work with regulair sizes but works with a 8 gb sdhc, now maybe there is hope for us :3

stankbot · « **Reply #218 on:** March 24, 2008, 11:29:38 PM »

Honestly, i don't know what to think about that post, since the guy used a different adapter than the generic one all over ebay and the transcend one, AND he didn't try to hook it up to the full sd but just microsd. with the generic adapter, i could get it to read full sized sd, but not sdhc, and the transcend one didn't work at all. (if I had a camera I would take pictures of a few other differences) But the transcend has an extra microcontroller on the adapter than the generic. And I think I killed the transcend one with head.

I am going to get another transcend one since thats what aliander is using and I am going to hardwire the sd adapter to a micro sd card as to avoid burning up the adapter. Unless we have another person who sucessfully got the adapter working and can tell us what mspd adapter they used. for sdhc.

PS I just ordered the card for semons or whatever. I'll let you know how it works out.

Hey guys, I'm new here, well kinda, I registered a while ago but this is my first post, but anyways back to the subject, I got this to work a few weeks ago, it took some trial and error but now it works just fine. I tried three different micro sd to mspd adapters and the one that worked the best is the Transcend one, but let me start from the beginning. The first adapter that I bought was <a href="http://cgi.ebay.com/MicroSD-Micro-SD-Memory-Card-to-MS-Pro-Duo-Adapter-NEW_W0QQitemZ150227572739QQihZ005QQcategoryZ50526QQtcZphotoQQcmdZViewItemQQ_trksidZp1742.m153.l1262" target="_blank">this one[/url], I couldn't format it with the PSP, so I had to format it with my pc and then copied the files from one of my MSPD cards, only my fat PSPs could detect the card though, and it stopped working after two weeks for no apparent reason. The second one I bought was <a href="http://cgi.ebay.com/ET-Memory-Stick-MS-Pro-Duo-Adapter-for-MicroSD-at-Store_W0QQitemZ270029672225QQihZ017QQcategoryZ15215QQtcZphotoQQcmdZViewItemQQ_trksidZp1713.m153.l1262" target="_blank">this one[/url], and it didn't work at all, so after looking for a while I finally found some Transcend adapters at www.datamemorysystems.com/ and www.memory.com/, I bought one from each place and they work great, I'm even able to format the 16gig SDHC card with my PSPs, fats and slims.

stankbot · « **Reply #220 on:** March 28, 2008, 01:32:44 PM »

GREAT NEWS!!!!!!!!!! The adapter from semons or whatever works beautifully!!!! Infact, it is even easier to solder!. If you get it thuogh, be warned, the entire top is not removable, just the area where the microsd goes and you still have to sorta rip the plastic, but nothing hot glue can't fix....Again, wonderful!

Correct me if I'm wrong. I can see on this video that transfers aren't bad. It's slower than original MSPD but it's ok. It is faster than UMD, isn't it?

It will always be faster,either being an SDHC or Micro SD.

stankbot · « **Reply #224 on:** April 04, 2008, 08:20:57 AM »

Sadly, I can't find the read speed of umds, but I haven't had any problems with mine. The only problem I have is when I compress anything, other than that, I run things full speed, and if anything does lag, its only been at startup. But its definately worth it.

hdx · « **Reply #225 on:** April 04, 2008, 09:45:51 AM »

If it's faster than UMD [I hope it is], It will be worth doing. I'm looking for Transcend Adapter and 16GB SDHC Card. I haven't got MSPD so I will buy SDHC. I don't play very often and It's good way for me.

Not sure if this is a dead thread or not and i wasn't sure if someone had already posted somethin on it, but i tried one of these out http://www.ameri-rack.com/APA-TFC1m.html. So far, with a 2gb SD 40 x speed stick my friend has for his camera, it works fine with the Transcend microSd to MS Pro Dou adapter i got. I like this setup, no soldering, but kinda expensive this http://www.ameri-rack.com/APA-TFC1m.html cost almost $39. Still waitin to order my 16gb SDHC (payday is comin soon), i will post when i got all of it workin together

thats actually a great idea. took me a while to understand but its pretty much http://www.ameri-rack.com/APA-TFC1m.html and http://cgi.ebay.com/2GB-MicroSD-Memory-Card-SD-Mem-Stick-PRO-Duo-adapter_W0QQitemZ270228489055QQihZ017QQcategoryZ18871QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
right?

that can easily become internal and done clean. if it works omg i might do it but its probably cheaper to just buy a memory stick pro duo.

I wouldn't get that one, it says that that adapter is not able to format the SDHC card with the PSP, just get a Transcend adapter, they are cheap and you can format the card with the PSP. I bought my adapters with a 1 gb micro SD card from http://www.datamemorysystems.com for $11.95 each.

im guessing its ok to remove the mspd slot completely right? im kinda scared because on the slim the slot is connected to the mobo. but its ok to do so in order to make it internal like that right? ty =]
