¿Puedes portar el Shader "crt-royale" a Dolphin? Intenté cambiar el nombre del que encontré de ".glslp" a ".glsl" y ponerlo en la carpeta de shaders de mi carpeta Dolphin. Aparece en el menú de mejora de gráficos de Dolphin, pero cuando lo selecciono y ejecuto un juego, solo me da mensajes de error. Probé los dos shaders de Dolphin que creaste y funcionan bien, pero no los prefiero. "crt-royale" es realmente un Shader CRT realmente asombroso en Duckstation que es casi perfecto. Me encantaría que hicieras que este funcione para Dolphin.
