I just got a Transcend 80x 2GB minisd to go with the M3 Mini SD and passcard 3 I just ordered. I have the Transcend card now so started loading games on it that way when my M3 Mini SD arrives I can start playing. Only think I have not been able to find out is how full can I make the card? Do you leave like 100 megs on it for saves or more? I dont know how much space saves take up? If I have like 33 games on it how much room for saves? Thanks guys very new to this.
