SEGA NTSC/PAL & LANGUAGE SWITCH ------------------------------- This modification will convert your PAL megadrive into a NTSC megadrive. Experience FULL SCREEN GAME PLAY!! Realy cool!! On most of the games the vertical retrace is programmed very badly or due to loads of graphix on screen the line becomes visible... In NTSC mode this will be a gonner... (most of the times :) ) _______________________________________________ ________________________ \ | MC68000 | | |______________________| | | ======================= | ======================= | | _________ : : : : | | 3 4 2 1 --------- before: ------- O O O O | | (Don't remove the CAPACITOR on JP1!!)
