Thank you to everyone who put so much time into detailing the various flachcarts pros/cons. I spent a few hours reviewing the material presented on this site and am looking for your opinions before I make my final choice. The Supercard DStwo seems to have many features and receives many "this is the best" comments. For those that have used the GBA emulation, is game music/sound accurately represented? This and the additional drain on battery life could be a deal breaker. If anyone has tested the difference in battery life, please let me know. There seems to be alot of potential in this card, but many posts point to bugs that have yet to be worked out. My other choice is the Acekard w/EZ Flash 3 in 1. Is there any reason to get the Acekard 2.1 over the Acekard 2i for my DS Lite? Please share your thoughts. The price for the Supercard is identical to the Acekard/EZ Flash combo so price is not really a concern here.
