you know, you CAN solder a switch on or pay someone too.. also how many games do you really PLAY online, theres brawl, and MK but what else really...
the odds of nintendo doing that are almost null, since they havent yet, and youre saying you cant do it, or pay someone like 10 bucks to do it?
on the chip front, D2Sun is popular and theres a lot of support since on WiiNewz their active, but overall i would stick to a chip more people use, and above all i dont see anything special from it
D2pro is a good chip, i had a lot of issues, but others shouldnt, i hear it works well, and decent support but i hear the group behind the chip are like ghosts
wasabi which i have, is good, it is the only one without the disc eject error, and firmware 1.4 blocks updates, meaning no questionable steps, no thinking wow my brother installed this that idiot, etc, its a good chip over all though
all chips are about the same, i would go with Wasabi but you cant really go wrong *unless you dont do any*
