61020: There was an error logging in to the GP backend.
It's not a Wiimmfi generated error code.
What is the GP backend? I was guessing that AC was keeping me from logging in, because when I turned off the codes, it allows me to connect. I used the codes Never Get Resetti [TNTkryzt], Buy Any Item From Catalog [TNTkryzt], Walk Over Objects [TNTkryzt], Always Have 9999999 Bells (works for any player) [brkirch], and Can Add Furniture, Move Furniture, And Take Furniture In Other Villagers' Houses And While Other Villagers Are In Your House [brkirch]. I'm thinking it's the last code, based on the fact that it says that there is furniture blocking my door. I'll try it out without the last code and see how it goes.
EDIT: I tested the game without the last code and it connected to Wiimmfi on my new profile, but it still gives me a 60000 on my old profile, even though I used PIDTool a week ago.
Clutz, I don't know if you're looking for a private chat room, a public chat room, or like a forum. If you're looking for a public chat room, there is ChatStep. You just type in the room name, the name you will have, and do a Captcha, then you're in. Though as I said, I don't know what kind of chat room you're looking for.
