|  Re: Is possible to create PAL/NTSC TED software switch?
On a real C16 or plus/4 you can switch TED between PAL and NTSC but that only affects the clock divisor for PHI0 and the screen generation (toggle number of raster lines). But on the real hardware the base input clock is different on PAL and NTSC computers, you have to replace the crystal too if you want to convert a PAL computer to NTSC or vice versa.
Perhaps it's easier with a reconfigurable computer but you I'm pretty sure that there is no new hardware register implemented to do the base clock switching. But - as gerliczer already said - you have to ask the C16 core developer.
