I have made available modified Demo3D from WTK2.2 for SonyEricsson K700, as the licence seems to give the right to do that (Paul is it ok?)
-Life3D is not modified but it is so slow to update that we tought it doesn't work...
-Pogoroo has a slow key response
-RetainedModeMidlet is ok
-M3G files are not compressed so they are larger, but has you already know, a zipped file in another zipped file is not always a good think for compression ratio ;-)
So check www.miklabs.com
For Nokia Demos, the licence is more restrictive so you will need to wait beta M3G-Converter ;-)
