Direct Solder SD Card adapter failure to load games

[rguerra0499]

Describe the bug

Using picoboot, swiss will load up from sd card adapter, but will not access games on sd card adapter. Citing " physical drive cannot load " Swiss v0.6r1622 work fine but not newer versions. Sd card adapter is solder directly to the memory card slot 2. this issue is only presented on newer versions of swiss. Note that swiss is renamed to IPL.dol before been placed on sd card adapter, though it does load up the newer swiss, but swiss will just refuse to access the sd card adapter.

Steps to reproduce

direct solder sd card adapter to the gamecubes memory slot 2 direct drop of newer swiss version been renamed to IPL.dol boot using picoboot selecting newer version of swiss ( will load up swiss) selecting sd card slot 2 on swiss menu will fail (physical drive cannot work)

Expected behavior

accessing games from sd card slot 2

Which SD card are you using?

[rguerra0499]

It's a micro SD card SanDisk imagemate 128gb formated to fat32

This is how I have it setup

Here's an image with swiss rev 1614 working fine

I've been hearing many reports of 128 GB SanDisk cards no longer working, but the one I've got has no issues. This sucks.

the error I mentioned seems to be that, but I'm surprised that certain games work and others don't, since I was playing Splinter Cell Chaos Theory perfectly in version v0.6r1668 and now I can't anymore, my card is Sandisk and I load it through a WiiSD, for now I'll stay on version v0.6r1668

Can you check your Chip Select is actually Chip Select and not Ground? Chip Select to Ground signifies a SD2SP2 2.0.

[AlfredoDore]

I tested it with another SD card and it is indeed the Sandisk, these last two versions prevent certain games from starting, something must have been put on it, but I will continue with the previous version since it is working correctly (and all my games are on it)

Can you try the latest CI build and see if anything changes? https://github.com/emukidid/swiss-gc/actions/runs/10650241524/artifacts/1878642728

[Massouille78]

No, same problem with this version

[Extrems]

Can you try both r1664 and r1667 to try to narrow it down?

Sorry, I mistakenly sent tests for Memory Slot B earlier. Please try these. tests.zip

[Extrems]

Can somebody please run these tests? I'm flying blind here and have nothing actionable still.

[rguerra0499]

Test file dump, witch ever file was used the dump was the same. this is using direct boot of a.dol file

[Extrems]

Sorry, these tests were for Serial Port 2. You need the Memory Slot B tests. tests.zip

[rguerra0499]

Can't really read the first line but this is the dump for both a.dol and b.dol respectably

I hope it helps somehow

Just an update of up to where swiss seems to work fine.

( Works )

( Doesn't work, detects something since it auto selects SD card slot B )

( Doesn't work, same as above )

( Same issue, doesn't load )

( Doesn't work either, got this one from last post )

If r1667 is where it's breaking for you, then you should really check your wiring. The SD2SP2 2.0 change is also applicable to Memory Slot B.

As for the others, you can try this build: https://github.com/emukidid/swiss-gc/actions/runs/10728515673/artifacts/1905293122
