Since it seems after I post my post in the bigger threads, people still ask questions about this. Ok this is what I know. I have 2acekards 2.i (bought at the same time etc) However, I ahve different Memcards. 1 HP 4gb sdhc and 1 pny 4gb sdhc. The game works perfectly fine on the HP memory card and doesn't work on the PNY card. I however tried to place the HP working card into the other acekard that wasn't working with and it made that acekard work totally fine. The PNY will halt after the professor speech and will not go any further. I have not yet tried to reformat the PNY card. I have not yet tried to make a SAV file from the good HP card and place it on the PNY card yet. So I believe the halting after the professor speech is due to the type of SDHC cards that people are using. I will be able to do more testing later.. I have 4 Acekards 2i's that were all purchased in the same "BATCH" and 3 types of SDHC cards and 1 2GB card. I will check some things out later and test stuff. But again though. Im real positive it has to do with the type of SDHC card.
