Diagram of safe area on 5.37 MHz NTSC VDPs like the NES PPU
- Red
- Danger Zone, top and bottom 8 lines
- Most TVs hide all of this. Keep NES scroll seam artifacts here if possible. Later consoles don't even generate this.
- Yellow
- Action Safe Area, 256x224, (0, 8)-(255, 231)
- Most TVs show some of this.
- Blue
- PocketNES Safe Area, 240x212, (8, 16)-(247, 227)
- Practically all TVs show this. Platforms, pits, and indicators are fine.
- Gray
- Title Safe Area, 224x192, (16, 24)-(239, 215)
- Marked on Nintendo background planning sheet. Keep menus, score, dialogue, and legal notices here.
The term "5.37 MHz" in the headline is used because the author intended for the diagram to apply generally to any signal source using TMS9918 rate, not specifically only the NES. The safe areas also apply to ColecoVision, SG-1000, Sega Master System, TurboGrafx-16 H32 mode, Genesis H32 mode, and Super NES.
