There are a few posts on it, yeah. However, no one really gets to the core issue- the supplied AR code is amazingly shoddy, and freezing becomes VERY commonplace as you progress in the game.
I've emailed the EDGE team, they've known about the issue since M&L was released, but haven't released a fix. One assumes they're waiting for a series of games to not work before they release new firmware, as they have in the past.
Though, there are rumors going around that the factory that produced EDGE cards has shut down and that the EDGE development team is essentially non-existant now. Time will tell on that one.
What would be amazing in the mean-time though, is if someone either A.) refined the AR code, or B.) came out with a cart-specific patch. Unfortunately I fail pretty hard at the skills required for either, so I wait (Somewhat) patiently. I guess if I REALLY wanted to play it I'd just get a hold of a Cyclo or an Acekard 2i.
