I just bought this a couple days ago for use in my 3DS. I somehow updated my 3DS to 4.2.0-9 and now the cart is blocked for use on my 3DS. My question is, can I use this 3DS compatible card in my DSi XL while I wait for new firmware for my 3DS unit? It looks like the DSi carts are specific to the console, but I've read a few things that look like this 3DS cart might be able to do both?? Just a bit confused is all. I don't care about GBA support, cheats, etc. So the R4 was an easy choice (having owned 2 in the past and familiar with them) Should I consider a different cart for my DSi XL? Not sure which is best these days on supporting the widest range of games with quick firmware updates Thanks in advance for info!
