- Not a look-alike filter: it builds a real NTSC signal, degrades it as RF reception, then demodulates. Artefacts are by-products.
- Phosphor mask: slot, aperture grille or shadow mask.
- RF loss: tuning error, phase noise, sync jitter, snow, AGC wobble.
- Beam misalignment and curvature give a real tube's false colour.
- Interlaced even/odd fields.
- Vertical (tate) games rotate the whole plane, scanlines and mask.
- No frame drops in normal use.
- Drop-in node, 48 parameters, 5 presets, MIT.
