I can't seem to find a definitive answer on this: does anyone know for certain if the NTSC and PAL Robotic Operating Buddy are interchangeable, and not set for either 60 or 50Hz or something? Trying to get a US R.O.B. to work with an emulator on a PAL-B CRT (S-Video) but no luck yet (could be a million things, trying to rule this one out). Thanks.
