Flashcart upgrade for DS phat - DS and GBA games

Hey!I've been using a R4 King LL cart and it has served me well, but when I try to play some relatively recent games (ie-launched beginning of this year to now) I've needed to experiment with a plethora of patches, kernels, Wood/YSmenus, etc to get the roms to boot. I'm not so literate with this kind of stuff but I've been patient and given it a shot. The end result, however, is that the games still don't work and my R4 kernel is now a chimera. I've had enough. I just want an idiot-proof card that will play any rom I put on it straight away, 99.99% of the time. Does such a card exist, and can I use it on my DS phat?My other question is about playing GBA games on the DS phat. As I understand it, there needs to be a flashcart in slot 2 to get GBA games, stored in the slot 1 flashcard, to work. Have I got that right? What I also want to know too is what kind of flashcart will I need to buy. Is the Ez3in1 the only one out there that will do the job?

Supercard DS Two plays most roms, and you don't need to patch them to play them and it can play GBA roms with it's emulator.
