Here&a video demonstrating Retropie running in 240p RGB on a 37cm (14") CRT TV. My setup: Raspberry Pi - cheap HDMI to VGA converter - DIY VGA to SCART cable - SCART TV My video settings are: hdmi_group=2 hdmi_mode=87 hdmi_cvt=336 249 60 1 0 0 0 or if your TV doesn&support 60Hz, here&50Hz PAL mode: hdmi_cvt=320 312 50 1 0 0 0 I came to the conclusion that 249p gives a much closer to spec signal than 262, with 262, raspberry pi outputs a 16.2kHz 59 fps frequency the horizontal frequency is a bit too high and the screen becomes more narrow, at 249 you get 15.6kHz at 59.6 fps which is much closer to spec. My HDMI to VGA converter is a cheap one you find all over ebay with the analog audio output I&done a cable using Cat 5e UTP cable a VGA plug, a SCART plug, an audio 3.5mm stereo lead, a USB cable, 2 1k resistors and a 100 Ohm resistor, schematic here (solder side): I used a USB cable instead of the molex plug (discard the 12V line, you don&need it). Cheap and easy, amazing 240p scanline goodness :D Here are photos, schematic and config file if you are interested: Here are my relevant video settings per emulator which looks best for me: All emulators: Aspect Ratio Index: Custom Interger Scale: OFF HW Bilinear Filtering: ON All other settings leave as is except the following: Atari 2600: Custom Viewport X Pos: 9 Custom Viewport Y Pos: 24 Custom Viewport Width: 320 (1x) Custom Viewport Height: 210 (1x) Atari 7800: CVXP: 9 CVYP: 9 CVW: 320 (1x) CVH: 240 (1x)...
