Reply to 1.4 Firmware questions

First off, thanks again to DaveX and the entire DJTT staff and community for not giving up on the vci-100.

1) Firmware 1.3 had a way to start it in 1.2, if I'm not mistaken, so will this one also have a secondary startup if you want to start with the older one (for whatever reason)?

2) Will this firmware work with older versions of Traktor (like traktor 3?) If so, does it come w/new .tks files/mappings?

3) What will change in terms of changes for Traktor PRO .tsi/mappings?

4) is the easter egg "disco version" just for fun (random flashing lights) or do they flash to any input?

5) Will the manual changes that DaveX stated (while in beta) still have to be made manually, or does the NEW mapping link that DJTT provides include them already?

I'm sure more ?? will come later, but these just came to mind.
