Now that there is a new DMA mode in 1.7, along with Old DMA and QuickSave DMA mode, I'm just curious about some things: 1. What exactly is the "yellow DMA" mode? How does it differ from the other 2 modes? 2. Does the new DMA mode offer better battery life for the DS? 3. It is already said in the front page news that this new DMA mode increases the efficiency of microSDs, but has anyone actually felt that everything has become better in terms of performance? I wanted to make this topic as I had problems with all of my save files since upgrading to 1.7. I've formatted my card, checked for errors, re-downloaded everything, set save types, etc.
