Hi, I have a DS phat & a DSi XL. I am looking to buy a flash cart for each of them. I would like to have these features: play games (of course), use cheats, and save states. Don't really need music or video playback. I know that the supercard dstwo has these features but I heard that it drains the battery alot. So I was wondering, is there any other cart that have these features but won't drain the battery as much? And also, since I don't have a credit card, do you think it would be safe to send the payment as a money order? Thanks in advance.
