What flashcarts work on DSXL/DSi?

So my DS is dying, the DS slot is not really recognizing cards and the left control button died, and my parents agreed to buy me a new one. However they want to buy a DSXL/DSi for me.At the moment I own a R4 Ultra and I'm afraid to buy a DSXL or a DSi because I don't know what flashcarts work on it. This might be noob-ish but can anybody please tell me which flashcarts work on a DSXL or a DSi? I know that the DSi cards need the 'i' at the end of the name but what about the DSXL, is there some special card needed or is it the same as the DSL?Thank you!~

Supercard DSTwo , Acekard 2i , R4idsn .

I would recommend the Acekard 2i with the unofficial firmware, by all accounts you cant go wrong.
