GCN DIY SD2SP2 installed internally soldering a micro sd adapter to GameCube Serial port 2

[wolffangalchemist]

I made a schematic a few days go and got it working based on the pin out of the SD2SP2, an alternative for those that just have this stuff laying around and obviously already know how to solder. i need to order some 22uf capacitors had to kinda "improvise" one.

how it looks inside for now, i need to clean things up a bit and secure everything.

Hope this is useful to someone, lets free up those memory card slots!
Edit: Including a link to some alternate points for adding sd2sp2 adapter to a DOL 001/101 units that lack a physical serial port 2 slot,( i can confirm this works)

My own ugly but functional magnet wire job testing these points.

This is amazing! And that looks fairly easy to solder too!

is this anymore reliable than the memory card slot ?

i don't personally have an sd gecko to mess with to test any differences in speed, compatibility wise though gs mes that use slot 2 for stuff works properly now. i just installed this and i load swiss-gc with a dvd-r since i have a xeno installed.
that said, so far everything has been running smooth and i haven't had any issues. I was playing melee with a bunch of mods to it and that crashed but i don't really count that, played regular vanilla melee no issues and some other games like beyond good and evil and some crystal chronicles no issues. reliability wise it loads from sd with no issues every time haven't had a hiccup yet.

It's the exact same thing as memory slot SD card adapters.

I've installed it and it works well, bit of stuttering on video, maybe the SD card not fast enough,

Try some decent branded class 10 memory, this is the card i have in my gamecube. https://www.newegg.com/pny-64gb-microsdxc/p/N82E16820177015 .
I Used it in my switch till i upgraded to a higher cpacity card hasnt given me any issues. Some games might have small problems with stutter but so what what i have played has been smooth.

Wait, this just works with Swiss straight out of the box, just solder the wires to an sd slot and you're good to go?
Really?

How is it for running games? Does it work well? Any stuttering? Any compatibility issues at all so far?
When running from SDGecko, audio streaming games such as Resident Evil 0 would have wild (and very often) skipping. Is THAT an issue (or would it be possible to check?)

I have a modified gamecube already (Viper GC OG), but it's a huge pain in the balls to burn games for it.

Would it maybe be possible to make a jack to plug straight into the external socket instead, so it's non-intrusive?

Any chance of a video so we could see it in action?

Resident Evil Zero does not utilize streaming audio.

That's what it was to begin with: https://github.com/citrus3000psi/SD2SP2

Wait a minute, so just solder an sd card female port to those pins on the board and

Oh.... I was under the impression that RE0 used streaming audio. Might be thinking of something else though.
Oh well.

Still, this is pretty awesome. I think I'll mod my GC with this over the weekend. I have an SD card reader I can rip the slot out of and stick it in the bottom of the console's front somewhere.

Thanks very much for this info, much appreciated and can't wait to give it a try

I can say that Crazy Taxi has no audio streaming issues on Swiss 646 from a regular slot-B SD card

 

[cyo_the_vile]

a lot but not all streaming issues lie in the fact that the BUS speed for the memory card and this adaptor port are the same and lower than the disc drive.

only sp2 have audio straming disabled? it instead works from memory card? when will be added to sp2?

 

[Dawbo2065]

I'll re check crazy taxi but I'm sure there is no music on any slot used, only by using the burnt disk.

You can use the old read patches with the SD2SP2, which support streaming audio. Just disable the alternate read patches.

 

[Dawbo2065]

Yes if you disable alternate patches on the game settings before loading, you will get the music in crazy taxi etc.. don't disable in the main settings otherwise it's still enabled for each game..
Works for all slots..

i know but games runs worse, example soul calibur 2 slow as hell, video freeze and game play stutter etc

when new patches will be added to sp2? they works on memory card slot (no old patches) or not like sp2?

Soulcalibur II doesn't use streaming audio. Keep them enabled for that game?

I don't understand the other questions.

i use pal iso, with alternate read don't work, with old read patch works but slow, intro crash, fightings stuttering...
the other question was sd from memory card slot do not have audio streaming enabled on alternate read patch like on sp2? You are on discord?


Also, why swiss report false "audio streaming game" message when the game is not an audio streaming one? example soul calibur and others..

Works for me.

Correct.

Because that's what the game developers set in the disc header.
