Read and Write roms to a GBA Flash cart's Mini SD card with an R4 and a DS Lite

[Shahaan]

Alright, thanks for the assistance. I'll have to figure something out with that

Does it hang there with no Slot2 device inserted?

Nope, boots like it should

Yeah so it's trying to access the card but something breaks it. Probably issue with filesystem then or the DLDI card isn't getting the correct responses from the card.


These are all the drivers I think could possibly work for your card. But assuming you tried them all already then yeah that must be an issue with the MiniSD card then...or the SuperCard Rumble DLDI driver needs to be reverse engineered and updated for new libnds. There was a similar issue with MaxMediaDock's driver until I modernized it and fixed it's IsInserted function. But I doubt this impacts this one. The fail with MMD impacted just the CompactFlash based slot2 cards. I don't see how any of the code would break in new libnds with the SD based stuff.

Yeah these all lead to the same result, tried them save for the moon one, which also just lead to hanging. I guess it's a lost cause

@Apache Thunder , maybe you can get his card to work with your GBA Exploader patch?

Assuming the SuperCard SD MIni uses the same mode switch code (pretty sure it does as I recall checking it's DLDI code while trying to help the original poster in this thread), my build of GBA-Exploader should already work for it for the most part. It does seem saves work too provided they don't exceed 64KB in size. SC specific patches might be required for the Pokemon games for example. I think it's due to the games overwriting the GBA Exploader metadata that is at the start since I assume a write past the 64KB boundry gets mirrored back to 0x0 which I think is what is happening with those games. Not sure what YSMenu/SCFW is doing to get around that but GBA Exploader doesn't currently handle that properly.

Also note YSMenu will work with it too as it does for mine. That's always the best fall back. Don't even need a flashcart compatible with it. Just DLDI patch it for your current flashcart (as long as it's not a DSTT clone that can be bricked by running wrong YSMenu though) and you can send GBAs to your card. Just select them as if you were booting an NDS file and YSMenu will handle that for you. That's what I was using for my N-Card prior to GBA-Exploader. You won't be able to boot NDS files with YSMenu unless it's a build compatible with your slot-1 flashcart but it doesn't matter with GBA games.

That would have been pretty nifty, I can only get this to load successfully though and it fails to mount the FATfs: 13

Edit: Also got a 4mb Atari game running with YSMenu, however that only seems to work on the DS side and wouldn't be able to be used for flashing stuff for my GBA or writing roms to the Mini SD in it
I think FTP would also be a pretty good way to achieve these things. But nothing can get to the storage in the flash cart to begin with so it's kind of like bleh

Oh yeah this all assumes you'd primarily be using the SuperCard MiniSD on your DS/DS Lite. If you intend to use it on a GBA then yeah you'll have to get the MiniSD stuff sorted out.

I got one and I never knew it would use some archaic form of Mini SD I can't find adapters for, so I have no way to really use it write now so is there some sort of DS Homebrew that would let me access the Mini SD in the cart and write roms on it from there to use on my GBA?

Here's a miniSD reader.
