theres a couple of things that have been bugging me for a while, and i was wondering if youguys could help. First of all, when i play animal crossing on WFC it crashes a lot, like every 5 minutes saying something about lag, im confused about this because i dont really see lag on maro kart WFC. Is there any sort of ping test i can do from my DS? This question has been on my mind since the launch of the DS: when i play gba games such as super mario bros 3, i find the button layout unatural, shouldnt the ds's B be the gba's A, and the Y be the B buttons. I was wondering if theres any sort of app that will let me launch gba games using a modified keymap. And the last one: what exactly happened to the supercard homepage? it hasnt loaded in weeks.

The A and B button issues are an oversight by nintendo as it happens on my originals as well.  Its hard to believe nintendo could be that careless with the DS, but I love it anyways.  A homebrew App for swapping the buttons would be nice, But I don't think Y and X are even recognized in GBA mode.  You would probably need either a GBA emulator (which would be a waste) or some sort of hacked firmware.  Hmmm.

The supercard homepage has always been shaky.  The last firmware was released even though the site was down so I wouldn't worry too much.  I have heard hitting refresh a bunch of times can make it load though.

BTW, your questions about Wifi do not belong in this forum.  You should rename this thread to something like "app for changing GBA buttons?"

Well, my question isnt really about wifi, its about a ping testing app. If the buttons arent recognised in GBA mode, would it be possible to run a gba game in ds mode?

From DS mode I dont think the GBA bios is accessable at all. From GBA mode the ARM9 is not accessable. That leaves trying to emulate the GBA while in DS mode, and I dont think the 2 processors are fast enough to hold the DS functionality while emulationg the GBA bios and system. I could be wrong though I think a GBA emulator from DS mode would be very slow.

What about some sort of firmware mod? Could the  firmware could be changed to use those buttons for GBA mode?

[Mullan]

From my understanding, the newly released firmware allows GBA games to run in DS mode. Theoretically this means that the x and y buttons would be recognisable right? Does this give hope to the idea?

edit: sorry for the double post, i didnt see an edit button before because i wasnt logged in untill i clicked reply.

Well, actually, running the GBA in NDS mode is possible (if not done already by the SC firmware) because you have total access to the NDS hardware, and that means you have total access to the AMR7 processor, so it's a matter of doing a dynamic adress interpreter, to change the running code to the correct processor.

How difficult is it to do a dynamic address interpreter?
