So I managed to get a slot-1 flashcart for dirt cheap, and got Godmode9i set up on it, but... I still can't access my WarioWare DIY save. I'm using the latest version of Godmode9i (3.6) and following the procedure at the bottom of the page here: [I can't seem to bypass the link blocking no matter how I mangle the URL, but the page is "Godmode9i FAQ & Troubleshooting" on the DS-Homebrew wiki]
When I use a normal DS game (without the weird NAND save chip) I can back up the save to the GBA cart, and then to my flashcart's SD card, just fine. However when trying to do it with WarioWare, instead of showing the game title it asks "Dump 'NO-TITLE_NONE00_FF' to GBA cart?" and only has an "All" option, without the menu entry to dump just the save. Attempting the dump doesn't actually seem to do anything, and when trying to retrieve the data from the GBA cart Godmode9i doesn't recognize there being any DS data saved on it.
I know Godmode9i was supposed to have gotten support for NAND cartridges a few years ago, but it doesn't seem to be working for me. How do I get it to correctly recognize the WWDIY cartridge and data? Is it just not possible to back up those cartridges using the GBA save method? I don't have a DSi or a passcard for my EZFlash IV so as far as I'm aware the GBA cartridge method for save dumping is my only option right now.
