→How to connect to a CRT TV
*An alternative to the above is to get a SCART to Component transcoder such as a CSY-2100 clone such as [http://www.ebay.com/itm/NEW-SCART-RGB-to-YUV-Component-Video-Converter-Scaler-/221156873851?hash=item337dfa167b this one] and make a VGA to SCART adapter using [http://www.nexusuk.org/projects/vga2scart/circuit this schematic,] making sure to bridge pins 5 and 11 on the VGA side. The clones usually need color adjustment, so pull up two NTSC test images (one on a color-calibrated display, and one on the TV), open up the transcoder, and twist the knobs with a screwdriver until you get the picture you desire. You will be able to output a 240p image with this method. Use [http://geocities.ws/podernixie/htpc/modes-en.html these modelines] for the console that you are going to emulate, or use lrmc to generate new ones. These modelines are RandR modelines, so if you are using Windows, use WinModelines to apply them. If using GNU/Linux or *BSD, use xrandr. If you are using GNU/Linux, make sure you use the open source graphics drivers, and not the proprietary ones. There is no need for any driver modifications like there is on Windows.
*If using a PAL TV with RGB SCART (make sure it supports RGB and not just composite through SCART), use [http://www.nexusuk.org/projects/vga2scart/circuit this schematic] to build a VGA to SCART converter, and that is all you need to do. Keep in mind that this schematic does not apply to Japanese RGB JP-21. Use the appropriate pinout for JP-21 instead in that case, available [http://www.gamesx.com/avpinoutswiki/rgb21pinjdoku.htm php?id=av:scart2rgb here]. It will work just the same.
*Most CRT HDTVs have either DVI or HDMI ports which can accept as low as 30kHz (480p at 60Hz) from a PC. They do not support 120Hz to force 240p resolutions while doing this.
