Sigh, this is what ticks me off on GBATemp, according to Gateway3DS's website:
- Can you play multiplayer local and mostly online?
Yes, but we advise not to use online features
- Do the game keep internet capacity?
Yes, but we advise not to use online features
For all we know, nintendo could have figured something out about how it may work and blocked online for it just like they sort of blocked the exploit with 5.X or online could have just never worked plain and simple and gateway was lying. Who knows.
