Metal Slug 7 Slow?

i searched to see if this was asked already, and im sorry if this is in the wrong place-im using Acekard 2i with AKAIO RC2 on my DS lite- and the game seems slow even when just a few enemies are around-I had a similar problem when i was playing Iron man 2- but that was resolved after reformatting my sd card-any solutions?

Well, there's AKAIO 1.7 out now. That may help - http://forum.romulation.net/index.php?topic=38335.msg695431#msg695431
