I'm running a brand new, authentic Acekard 2i on my DS Lite, which works perfectly for regular games. Initially, I uploaded the default firmware from www.acekard.com and things were going smoothly. However, it gradually began to not detect the cartridge, taking more and more times to boot, and sometimes acting as if the cartridge had been taken out in the middle of playing a game (clean backups). This became obnoxious, so I reformatted and reinstalled the default firmware. It worked 1 time before failing to start after 50+ tries. I reformatted again with Panasonic reformatter with AKAIO 1.4.1 and its 5/4/09 loader. It has failed to start with this as well. If I do auto mode (instantly start whatever game is in the cartridge,) both screens become white and nothing happens. If I do manual, the place where you select the ds game does not say no cartridge is in, but has no text and a blank white avatar, and if chosen, results in the same two white screens. I'm completely at a loss and very frustrated, and if anyone were to help, I wouldn't mind sending a token of appreciation, $5-10, on paypal.
