It might be possible to move the pixel shader computations to the vertex shader in the future.Since there are only six vertices, this shader should be very fast. Most of the computation is done on the vertex shader.The height of medium-resolution arcade games (e.g.If there is a way to get the Raspbery Pi composite hardware to shrink the 720 horizontal pixels down to a 4:3 aspect ratio, we would get crisper image horzontally.Please feel free to submit any improvements. It's because 192 fits into 576 three times rather than two. It's possible Sega Master System games will appear too tall on PAL TVs unless you shrink the video height to less than 576 lines or enable vertical borders. Tested only on a Raspberry Pi 3 on NTSC but should work on PAL as well. It will also make two-screen games more playable by only showing the bottom screen (e.g. Will fit vertical games correctly on horizontal TVs. Set the filter to "Linear" in the Quick Menu/Shader menu.In the Quick Menu/Shaders menu, set the shader to the basic or deluxe version of this shader. In the Settings/Driver menu, make sure "Video Driver" is "gl".Make sure "Bilinear Filtering" is off in the Settings/Video menu.As usual, not sure why there is so much certitude over whether it is possible or not. Only recorded it on Nestopia though, if only to prove that a Round 1 victory is very much possible. Set the Custom Aspect Ratio to 640x480, or the PAL* equivalent. Yea, beaten Mike Tyson on pretty much everything, from Playchoice 10 to NES to NES Classic to emulator.In Video settings, set "Aspect Ratio" to "Custom".This ensures 240p with "scanlines", just like on original hardware. In /flash/config.txt, set sdtv_mode=16, or 18 for PAL.Copy one or both shaders to the Shader folder of your Raspberry Pi.Aligns lines vertically so that only horizontal linear filtering happens.Centers games instead of stretching them.Virtually eliminates the need for separate configurations per core (console). Makes games crisp vertically, and not shimmer horizontally.Ĭorrectly aligns the games for you regardless of console. (This may also work with the RetroTINK, as well as other systems that use RetroArch).Įnsures games on CRT will look as good as on original hardware. For Raspberry Pi with built-in composite out to a CRT TV.
