OK, I'll come out and say I'm a noob to all of this (obviously considering my previous posts), and I just want to settle with buying a DS flashcart rather than a $90 card. I have been looking all over, but it was so confusing to find what's either compatible and/or what's actually legit. I'm looking for a Flashcart that can mainly play both DS and GBA games and is compatible with the Old Nintendo 3DSXL system on firmware 10.4. That's all. I don't know which version of which R4i card or whatever to buy that can satisfy me. I know most of these cards are like under $20, but still, as any regular person out there, I don't want to end up buying one of these cards, waiting for about a week or so and then realizing I wasted $17 on something too outdated or just all around fake to work with the system. I've had this happen to me so many times and I cannot be too lenient anymore on these things. Please, someone with any prior knowledge or experience, redirect me to a totally trusted website that has a card that can perfectly satisfy my needs. That is ALL I need, thank you.
