All of the cartridge hardware is identical. It is entirely up to the software whether a cart is playable on NTSC, PAL, or both. Unfortunately, there's no way I know of for a cart to distinguish between NTSC and PAL other than by requiring a user to use difficulty switches, the color/BW switch, or some other means to select. [For some really fancy carts there may be a difference between PAL and NTSC hardware, since I think the CPUs run at slightly different speeds. Not positive, though.] Quote Link to comment Share on other sites More sharing options...
