I’m trying to find a good CRT shader for RetroArch to preserve transparency effects (like the waterfalls in Sonic 2) and dithering. The problem is, a lot of shaders that are lightweight enough (easymode, lottes-fast, etc.) don’t seem to do the trick, the ones that work well (sonkun, royale) are too heavy for the hardware, and some that might be solid contenders are made for 1080p+ resolutions and create giant, goofy scanlines at 480p.
The handheld systems are so easy with the lcd-v2-color shaders, but finding a good CRT shader for home console emulation has been tough with this device.
Anyone have a good recommendation?
Dunno if its any better than what you are already using, but I just use TV-Out + Interlacing preset. I actually made a thread about this on libretro, here are the answers I got.
That answer suggesting crt1-tap is new since last time I checked it… might have to give that a try when I get home.
Problem is 480p is simply not enough pixels for most shaders to do their thing. If I was to upgrade to the RP3 this would be my main reason.
