I hadn't seen this anywhere so I thought I'd post this info. I was searching around the chinese www.gbalpha.com site and found that the 4.6e loader and the Mediaextendplayer v. 3.1 had been released. From the translation I got it looks like the new loader supports the new Mediaextend. It says the loader for GBA is still in V4.4 and the loader for NDS is at 4.6f. Apparently the new Media extend has better support for DPG and DPM movies..but due to the translation the technical stuff was hard to understand. It also has different ways of showing JPEG images. The ebook reader seems to be the same. The GUI is new and has a few new options but I'm not sure what they do yet.
