I'm not into chips in general, so I can't say much more about these that what you've probably already read.

did you get it to work. i am tring the same sort of thing but using a old card reader to hold the sdcard. cut a hole in the back of my gc to mount the reader and follower the wire diagram but nothing. im booting swiss775 from disc and choosing sd2sp for the source in swiss. i see the progress bar for about a second then it dissapears..

Yes, but as long as the public release of SWISS wasn't compatible and confirmed working with Citrus's µSD card reader, I was not able to test my "homework". ;)
And, no, it doesn't work (My homemade reader). :oops:
the capacitor, if electrolytic, must be very close to the SD slot you want to transform into an SP2SD.
otherwise, it will not work.
weld your legs close to the solder point as much as you can. IDE wires are great. keep only 8 cm or less.
make 1 bridge in both GND.
use 22uf capacitor for 25volts or 50v

the diagram presented in this post is correct and works. just change the capacitor to 25 or 50 volts.
it worked for 50volts for me.

Yes, it works, and without the cap, see what was the problem:

Yes, I have crossed the lines, this is because of the different erroneous sources such as your diagram.
In a dedicated serial connection, one has to cross the lines between DI and DO from both side, but on SPI, serial data lines are named MOSI and MISO, because the lines between Master and Slaves must not be crossed, you wire MOSI to MOSI, and MISO to MISO.
So the diagram may be right, but the pins namings are wrong, and lead me to error.

Does anybody know if the chip responsible for the CS on SP2 is still on Dol-101 MB? Since we can get any of the other useful signals for an internal SD2SP2 adapter, it would be nice.
I'm really sorry for bumping this dormant thread, but I want to know if you ever found the answer to this? Reason is I want to know if there's the possibility of readding the SP2 functionality to the DOL-101 MB, since that's the only Gamecube I have. I know the contacts points have been traced, and I have found diagrams for it (here and here), but I want to know for sure if it's safe to proceed, so I don't accidentally break my cube.

Besides identifying the solder points and needing the 22uf capacitor, should there be more components required in theory? I'm just asking about the electronic components and not the connector itself, because I plan on adding a direct Micro SD reader to the motherboard that acts like a hard-modded SP2 port.

The diagram for DOL-101 is rigth, you only need the microSD reader

Hi, I wanna install internally sd2sp2 on my Gamecube Dol-101 and I need help to know where solder the 2 grounds and power wires from sd card to gamecube's board.

did you do this scheme on a Dol 101? following this diagram will be all right?

and you Papy.G, managed to work on a 101 dol? and the capacitor, where does it go in this scheme? :?:
a cousin of mine has a dol 101, I want to use an SP2 for him ... ;)

Didn't already, seems that many experience problems doing this mod.
I wonder if it is safe to solder straight in the vias under the CPU, as it can heat and desolder the BGA…

I have slots on cards with cap already in place, and some without and I won't add them at first, it must be the closer to the SD slot.

this information is quite relevant. :!:
my first homebrew SP2sd i had some frustrated capacitors. :? :cry:

However, when trying to solder a citrus SP2SD2 on the plate, it heated up to fry the PCB. I think there should be a sink. :oops:
I will work as soon as possible, this is an essential mod ...
:idea: :arrow:
what problems are presented? heating of the BGA. :?:


But this is strange, because the 3.3 volts that seemed to me responsible for heating. :geek:

because they are not extracted from that area. :?:

There's no point in getting a Citrus SD2SP2 to eventually solder it.

Heating while soldering is the main concern.

If I ever do this, I may try from a distant via, not right under the cpu, if available.
