if you sold it to someone here, you could get them back, depending on two things.
1) they didn't delete them
2) you could send them a mem card
3) ms' wonky drm wouldn't block you from retrieving them.
also know that technically, this is what got a lot of people's tags flagged as cheaters for achievement twinking.
btw, when did you become calvin/atb?
welcome back ridah. i didn't delete you from my friends list during your absence.
