> It's not guaranteed to work, due to the timing differences between the NTSC and PAL standards. But the lockout chip hack works. I have a few PAL NES games and they work mostly fine on my NTSC system.
Yes, most games seem to work, but quite a few have graphical glitches. A small proportion will be completely unplayable. And of course, games play about 17% slower than they should. (But most PAL NES games were not speed-adjusted apart from the music, so they are too slow on a PAL NES as well.)
The best option, if you have an NTSC-capable TV, would be to get hold of a US NES. If your TV isn't NTSC-capable, the picture would likely be in black-and-white. But still, it would be full screen with no borders.
I have a few US NES main boards, if anyone is interested; swapping the board with that of a spare PAL NES would be more economical than getting a whole US NES shipped from the USA. (I'm in the UK.)
