NTSC and PAL describe analog color-encoding systems. In retro gaming, people also use the names as shorthand for regional console and game versions. That shorthand is useful, but it can mix together color, display timing and software differences.
The common analog comparison
| Common system | Total scan lines | Interlaced fields per second |
|---|---|---|
| NTSC, commonly 525-line systems | 525 | About 59.94 |
| PAL B/G, commonly 625-line systems | 625 | 50 |
Total lines include blanking, so they are not the visible picture’s resolution. Fields are also not the same as complete interlaced frames: two fields make a frame. PAL variants exist with other timings. Tektronix’s video measurement guide documents these distinctions.
Why some PAL games feel slower
Some older games tie logic or animation to display timing. A poorly adapted 50Hz version can run slower or show larger borders than a 60Hz version. A properly adapted release can compensate, so the result must be checked game by game.
Regional versions may also differ in language, censorship, bug fixes and save compatibility. Choosing a 60Hz version is not just a universal picture-quality upgrade; it can mean choosing a different software release.
Original hardware and modern displays
For an analog console, check the console region, cable, television or scaler’s accepted signal, and any region restrictions. An adapter plug does not necessarily convert an unsupported video format.
HDMI displays use digital formats and refresh rates. A modern 120Hz television is not a “PAL television limited to 50Hz.” Look at the supported HDMI modes and the console’s output settings instead.
Emulation and preservation
Use the timing appropriate to the game version. Forcing another region can change speed, audio or compatibility. Compare default settings before changing resolution, filters or synchronization.
