The point is that great software that's available from 3rd party developers that's Video Toaster only that could be enjoyed by Amiga users. It's no longer about NTSC. Not to mention the awesome software package that came with the Video Toaster/Flyer itself. From a preservation standpoint and an opportunity to get a bunch of additional software running in a Amiga Virtual Machine that's interesting to study and use. You are right NTSC timing does not matter anymore and that would not be the point.
Still, what is the point of using an FPGA for this?
If preservation is your goal, adding the required functionality to highly portable emulation software is surely the better move.
