Overview
PAL vs NTSC describes the regional video standard differences that significantly affected gaming. European PAL systems ran at 50Hz versus NTSC’s 60Hz, meaning games often ran 17% slower with wrong-pitched music and black borders, unless specifically optimised.
Fast Facts
- NTSC: 60Hz, 525 lines (USA, Japan)
- PAL: 50Hz, 625 lines (Europe, Australia)
- Speed difference: ~17% slower in PAL
- Optimised PAL: Rare, required extra work
- Impact: Music pitch, gameplay speed

Legacy
PAL vs NTSC differences gave European gamers a fundamentally different experience. The 17% speed reduction affected difficulty, music, and gameplay feel in ways that weren’t fully appreciated until emulation allowed comparison.
