Ok look,
For all of you morons thinking that NOT HAVING ACHIEVEMENTS will make you safe on live. THINK.
Doesn't the emulator have it's own save?
Doesn't the emulator save things in your profile?
Do you think M$ isn't going to check for those things in the next update??
Don't use any homebrew on your live account if you're scared of banishment. M$ is going to add the checks. Bet on it. Stop whining pointlessly about a feature. If you dont want your kids or your wife or your retarded cousin's husband's father logging into your profile make it so it doesn't auto-log in. Then make a bunch of fake profiles named a, aa, aaa, aaab, aaaad, az, aza. This way the idiots have to scroll over to find your particular profile.
Or better yet, MAKE A PROFILE THAT LOGS IN AUTOMATICALLY.
I personally LOVE the fact that homebrew has achievements. It was one of the things I asked 'anonymous' for.

We are thinking. If the game is a DEMO, it will not leave a trace on the profile. Also, we don't transfer savegames around, just the profile. No one is whining here moron. Like I said, this is a place for people to leave feedback about the software: bugs, suggestions, and problems.
Your suggestions are good, and already used by many people, but not good enough.
P.S. I don't understand why some people are being so hostile about this. Seems that the ones who want the achievements are really letting this get under their skin. I don't like the achievements, other people do. Deal with it.
