I'm just going to hijack this topic as it seems to have been answered and my question(s) is (are) essentially of the same nature, though tweaked a bit.
Question 1:
I, too, am looking to buy a good slot-2 card compatible with the r4ds, though my priorities differ. Ideally, I'd like to be able to save anytime, fast-foward, etc on GBA games, though my biggest priority is for them to run well. If this puts me up into a higher price range, so be it. I don't care about browser support. Just games.
Question 2:
I have an SNES emulator on my slot-1 card (SnemulatorDS or something of the like) that has a lot of layering and overall functionality problems. I've read that many of these problems are due to the slot-1's card just not having the same power as did some SNES cartridges. Seeing as how the same limitations apply to GBA games (though theirs is a complete incompatibility), I was wondering if SNES games function better on Slot-2 cards, and if there are better emulators.
That'll be all.
