I am looking to write data to DS flash cards. I have a 512M DS flash card model E202650 without backup memory. I am interested in the difference between different flash card models. I have seen ones with white stickers and also ones with black stickers. So what's the difference between these? TWL and NITRO? And do all models of backup memory work with both of them? It would be even better if someone has the WarioWorld webpages describing all Nintendo DS hardware. I am surprised to find so little WarioWorld stuff posted here since DS has been unsupported for so long. Thank you.
The difference between the two carts you linked is at least their storage capacity. First one is 512 mbit, and the spongebob one is 1gbit. I don't know if the sticker color has a meaning or not... TWL flash cartridges got the same size than the NTR ones, but they are white colored, with a pink sticker. To write on them you need a devkit. And I can't help for the WarioWorld stuff, I don't have any access there sorry.
There must be some difference other than size because my 512M one has a black sticker. I have a devkit capable of writing to NTR and TWL cards so that's not a problem.
I noticed that the black ones are labeled SP and the white ones aren't. If anyone knows what that means please let me know.
