Convert Atari 2600 Jr (Long Rainbow) Pal to NTSC

The consoles are the same, except perhaps the power adapter. The difference is in the games themselves.

This is not correct. The chips differ even in the pinout. Take a look at http://www.atariage....a-ntsc-and-pal/ and look for AUD1.

 

Not only is the TIA different, but the clock of the TIA/CPU is also slightly different, which is the cause why the audio frequencies differ a bit.

 

señorito, rather than going for converting a console, I'd buy an NTSC version on ebay, and mod that one with composite output. More costly, but the chances on success are much higher.

The 2600 doesn't have any region lock system, so it will run games of any format, anyway the palette is different between PAL and NTSC TIA chips, and the frame rate is deternmined by the game program. So if you mix games and console with different formats you will have a TV signal with the color encoded according to the format of the console but with number of scanlines and framerate according to the format of the cartridge. Even if your TV accept that non-standard TV signal (PAL TVs usually displays a 60Hz signal without problems), the colors in the game will be incorrect because of the different palettes and there's no way to correct that.

 

This only applies to the 2600, other consoles may behave differently: usually the frame rate is not determined by the game, but by the graphic chip in the console and sometimes it can be selected by changing the signal on one of the pins (you can install a 50/60Hz switch in that case) and the palette might be the same or very similar between different formats.
