Terminology

Short for Phase Alternating Line, PAL is the television standard in Europe, Australia and most of Asia (with Japan as the exception). The United States and Japan use a different standard, NTSC. Whereas NTSC delivers 525 lines of resolution at 60 half-frames per second, PAL delivers 625 lines at 50 half-frames per second. Many video adapters that enable computer monitors to be used as television screens support both NTSC and PAL signals.

The PAL format is especially important for emulation, since early games marked as European were encoded specifically to run in PAL mode, while video games marked as Japanese or North American were encoded specifically to run in NTSC mode. This has important implications for playback due to PAL's 50 Hz and NTSC's 60 Hz screen refresh rates, which, if not compensated for, can cause undesired side-effects.
