NTSC (shortness of National Television System Committee) is a type of broadcast signal in various American countries, including Japan. The format was born in 1941, and was obsolete on the 2010s in most countries, due to his switching from analogue to HDTV broadcasting signal.
In the games
Most NTSC-J games can be played on NTSC-U/C / PAL-M/N systems. Generally, NTSC games can be played on Japanese and North American televisions. However, if you use RF signal, some Japanese systems such as the Famicom cannot broadcast the signal in the Channel 1 or 2 in USA standards, which will available in Channels 95 or 96. This occurs due to the band rate of broadcast signal in Japan is much lower than the US one. Aside from that, NTSC-J systems must be played on 100V outer walls. American and Brazilian houses outer walls uses 110V ~ 120V, so, there is a little chance of your console being overheated. You can solve this problem by just using a transformer
no, not a Takara toy. ;)
NTSC-U/C games can be safely played on PAL-M/N systems (PAL-M is from Brazil, PAL-N are from some South America countries). In order to play NTSC-U/C systems using a RF Switch, you must buy a Transcoder if you don't have a 2000's TV, which can automatically switch the color system.
NTSC games from any region cannot be played on PAL/SECAM systems (unless if the game supports it), because of:
- Slow framerate (50hz compared to 60hz);
- Hardware locking (common on Nintendo systems);
- Software locking (common on Sega systems)
You cannot play NTSC systems in PAL/SECAM outer walls without a transformer, their voltage rate is 220V ~ 240V. Doing this, your console is about to explode!
