I hate barging in while everything is getting out of hand. But, I was able to get the patcher that was linked from the French website http://codlab.1allo.com/nds/coaa.html to work and I dunno if I can help. I kind of feel like I'm adding on to the useless posts that are already all over this...

and i mean all of them (if not, maybe a few highlights, like TU1, TU31, and TU69)
