A set of these overrides is available for lr-mame2003, lr-fbneo and lr-nestopia in this forum topic. Rather than add logic to the shader (making it slower), a special version for vertical games is available:īoth vertical and horizontal games can be improved further by using special override CFGs that increase the accuracy and alignment of the scanline effect. Whilst libretro shaders automatically rotate for this, the shadow mask effect does not, causing an unsightly 'rainbow' effect.

Some arcade games were run on a vertical CRT a regular TV flipped over on its side. Presets are saved under the following folder:Ĭonfigs\all\retroarch\config\\.glslp Scaling artfacts (particularly in Vertical games) You can can save per-game or per-core, via opening the RGUI within a game with player 1's Hotkey combination Hotkey+X, then Quick Menu > Shaders:

Then, set Video Shader Enable to true and then set Video Shader File to the desired shader. Choose Configure basic libretro emulator options, then choose a specific emulator or Configure default options for all libretro emulators to make the change system-wide. You can select either preset via the Configuration Editor. Most default emulators in RetroPie are Libretro emulators, but you can confirm by looking for the lr- prefix in the emulator name via the Runcommand. Note: These shaders can only be used in Libretro emulators. The final 2 presets are zfast_crt_standard_vertical.glslp and zfast_crt_curve_vertical.glslp for vertical games, as with crt-pi. The second two presets are crt-pi-vertical.glslp and crt-pi-curvature-vertical.glslp, described in Vertical games has developed the zfast shader, which seems to perform even better. It is highly configurable, but four presets are included in RetroPie:

Fortunately, community members have built CRT shaders around these limitations: has developed the crt-pi shader, that aims to maintain full speed at 1080p on even a Pi 1 (overclocked).

Unfortunately, the Raspberry Pi series feature fairly weak GPUs that struggle to run complex or multiple shaders. Shaders are small programs that a dedicated graphics chip (GPU) runs to alter the image. Rather than today's flat screen displays, CRTs were not flat, and always featured some degree of curvature to the glass screen giving a 'fishbowl effect': Further, different broadcast regions had their own colour, resolutions, refresh and cabling standards, so a UK TV ('PAL' standard) would show the same game differently to a USA TV ('NTSC' standard). This can have a pleasing effect by making the image smoother. The cabling used to connect consoles to CRTs was typically analogue and introduced noise to the image. This describes the effect of lighter colours (particulary white) bleeding into their surrounding pixels, again helping to make things look less jagged: As well as helping to look like a CRT, it also helps to make the pixels seem less jagged and helps provide definition: Broadly this is the horizontal dark lines that appear when using a CRT, and also darkens the image slightly. Fortunately, there are ways of emulating CRTs. Further, old games themselves were designed and tested using the same televisions, so the raw image RetroPie outputs by default may not be the original artists' intention.

For some, this can appear jagged and harsh compared to their memories of the smoother, less refined output of old CRT televisions.
