I'm using a chinese G6 Lite with v4.1b software on it. I've had it for nearly 2 weeks and I've never been able to save in a game, turn off the DS, and have the save written when turning it back on. The only way to get the "saving data ... please do not turn power off" (I don't know the english wording) screen to show up is to use a soft reset or very quickly turn the power off and back on. I decided to let the G6 Lite charge in its USB cradle overnight, but that didn't seem to fix it. Any suggestions?
