Support for Gamecube SD2SP2

[tjanas]

Currently unable to run GCMM effectively via Swiss using SD card connected to serial port 2 (with SD2SP2 adapter). This is a feature request to support SD2SP2 just like Swiss and GBI.

I've checked and seems I only need to update libfat and little extra tweaks to add support. Should be easy enough, but I won't be able to test it since I don't have the hardware

[tjanas]

I would be happy to test it.

Hi, here's 1.4g, I'd be happy if you could test the gamecube version for SD2SP2 support.
Do you own a SD gecko? I ordered a SD2SP2 myself, but don't know when it'll arrive.

Changes: (no changes in wii version besides compiling with latest libraries)
GCMM will test for a SD2SP2 device. If it finds it, it will attempt to use it as a fat device, then will ask which Memory Card you want to use (as in wii mode, where you can select which memory card to use).
If sd2sp2 device is not present GCMM will work as always and ask in which slot the SD gecko is inserted.

Also, now pressing START in gamecube mode should properly reboot the console when no payload (i.e. PS0 exploit) is present. Could you test this too?

Also, it'd be great if you could test importing a Fzero or PSO savegame (copy protected saves) from a different memory card and see if it still works the same (it should, but I'd like to test it anyways since I had to rename a function for compiling compatibility).
EDIT: removed link, see further messages

If everything is fine I'll commit changes and put it on releases page

I do not have an SD Gecko. I will test copying an F-Zero GX save from a different memory card in addition to pressing start to reboot the console.

[tjanas]

Pressing start to reboot / exit on GameCube did not work. I quickly saw “Exiting” flash where the “Choose your mode” text is, and then the interface froze (no longer responding to buttons, reset button on console doesn’t work).

[tjanas]

I tested backing up an F-Zero GX save from one memory card, and then restoring to another memory card, and that worked fine.

[suloku]

Just checked the code, I actually forgot to change the argument for gamecube reset even though I added the code to handle it differently...I'll reconpile in a few hours. Glad sd2sp2 support works fine.

[suloku]

OK, may you be able to test reboot in gamecube? If this works as intended I'll make the release and push changes to source, thank you for your collaboration!

I tried this latest beta and it still has the same issue with reboot.

[suloku]

I'll check how swiss handles rebooting, seems libogc functions don't work for whatever reason

Just finished restoring some data using 14g on sd2sp2, works a charm! I don't know how rebooting works but I have the hardware so if you need any aditional testing done HMU

Needs EXFAT support for SD cards

[carstene1ns]

@vxbinaca not likely to happen. Also not much reason to support it.

[vxbinaca]

@carstene1ns This isn't 2010 where we're using 4 gig SD cards in Gecko adapters, today card capacity in hundreds of gigs exFAT support is wise

[tjanas]

@vxbinaca I believe exFat is supported by Swiss itself and GBI so it is possible but not within the scope of this particular issue (perhaps open a separate issue for this request).
