I'll have a look at it tonight. Are there any features in particular that you wanted us to test out? Would a password protected wiki page make it easier to note bugs ?
Give the lighting enables a workout. Try the different permutations of controls, event, attract etc. Also, try creating a GAMENAME.lsq file for some games to override the automatic selection of control lighting. Give the intensity stuff in the LEDWiz.cfg a try if you have RGB buttons (or if you don't too). A lot of the lighting code changed to reduce the use of the PBA command now that it is slower. Not much is new feature wise but a lot of stuff changed for future enhancments and for the speech stuff.
You can just email them to me.
