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 #handhelds 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.
YSK that there is a faithful 16-bit fan remake of Sonic: Triple Trouble, now available for Android. It runs beautifully on the RP2+ and supports both 4:3 and 16:9, so it should be a great experience on any Retroid handheld. (gamejolt.com)
