Derek's 'Lottes-Like' HLSL: (My Daily Use - Favorite, some distortion but at least you get screen curvature and scanlines, and you can't see distortion at normal viewing distances anyways, looks so much like Lottes and is the best all-arounder you're gonna get in HLSL): https://drive.google.com/file/d/1fTkz...
Derek's 'Lottes-Like' HLSL Flat (No shadowmask distortion up close!, Screen curvature distorts shadow-masks in HLSL unfortunately): https://drive.google.com/file/d/1CYWE...
(Must Zoom in if you want to see the accurate Shadow-mask effects on these below, they're all flat without Curvature or Scanlines for maximum Shadow-mask/Slot-mask/Aperture-Grille faithfulness):
