No, you can't. Nintendo DS don't support multiplayer for GBA games.
you have to have a super wireless adapter
no, only on a gba with the wireless adapter or connector cable, sorry.
no
I don't know about the wireless adapter, but you can have a wire adapter and use it on you GBA (Game Boy Advance). YOU MUST HAVE A GBA TO ADAPT WITH THE WIRE, it doesn't fit on the DS. I don't know about the wireless but maybe someone else will later put the answer later on.
No, the GBA part of a DS is unable to use the DS' wireless capabilities, even for games that supported the use of the GBA wireless adaptor.
No, the wireless function on a DS can't be accessed by the GBA portion of the console. If you're playing a GBA game on a DS, it is unable to use the DS's wireless function to connect to either another DS, or a wireless enabled GBA game on a genuine GBA console, such as FireRed or LeafGreen.
The GBA slot on a DS cannot use the DS' wireless capabilities, even if it's a game that was compatible with the GBA wireless adaptor. You'll need genuine GBA consoles to do it.
absoulutely not!, the DS has wireless built in.
A DS's Slot-2 (GBA slot) is unable to use the DS's wireless capabilities, even if it's a GBA game which could use the GBA wireless adaptors. You can only use the online portions of a GBA game using an actual GBA and a GBA wireless adaptor.
There is a wi-fi adapter already inside the DS.
No. There is no port on the Nintendo DS that supports the wireless adapter. Therefore, communicating with the Gameboy Advanced SP is impossible. You may argue that the DS itself has wireless capability and should link up without the adapter, but no. Games which use the wireless adapter in the SP cannot work with the DS (even in slot 2) wireless network. Try it. It simply asks you to insert the wireless adapter. And you can't do that on the DS.
