is the FC twin compatible with both PAL and NTSC cartridges?

[Diminuendo]

or can it be made to without adding too much size?

ok, I've found two things that might help me do this;

I don't enough about circuitry to be able to do this, but if some one could show me what to solder too what I think I could manage this. Also does anyone know of I could add a switch to swap between 50/60Hz

I found this too;

for this I want to know if it adjusts for the speedup problem that comes with using a PAL game in a NTSC console. Also, knowing the size of the unit would help since this might be a portable attempt.

thanks for any help in advance.
