Its easy to mod a NTSC console to display PAL-60 as they are nearly the same signals.
Its 50Hz PAL that needs a bigger buffer and not 60Hz PAL
50Hz PAL has more lines in a frame, so the buffer has to draw more (although less frequently)
60Hz PAL uses the PAL-60 standard, this was created by DVD Manufacturers I think about 8 Years ago, all they did was use NTSC signals but use PAL colour coding (as NTSC colour coding is not very good)
So it is easy to mod a NTSC console to display PAL-60 as it is not converting the Hz or Signal and only adding PAL colour coding to an NTSC Picture.
This means PAL-60 is smoother than PAL because there is only 483 lines (NTSC) so the frame buffer can be coded the same as the NTSC version due to same Hz, same lines.
The problems is with 50Hz PAL because of mores lines in the frame, means more additional processing (and bigger buffer)
