    240p-test-suite

    A homebrew video suite for game consoles

    Downloads are now available at https://artemiourbina.itch.io/240p-test-suite A homebrew software suite for video game consoles developed to help in the evaluation of upscalers, upscan converters, line doublers and of course TV processing of 240p video. The Wii and Dreamcast versions have modes for 480i and 480p evaluation as well. It has tests designed with the processing of 240p signals in mind, although when possible it includes other video modes and specific tests for them. These have been tested with video processors on real hardware and a variety of displays, including CRTs and Arcade monitors via RGB. As a secondary target, the suite aims to provide tools for calibrating colors, black and white levels for specific console outputs and setups. Current platforms are: Sega Genesis (Mega Drive), Sega CD (Mega CD), PC Engine/Turbografx-16, Super CD-ROM2/CD-ROM2, NES/Famicom, Super Nintendo/Super Famicom, Sega Dreamcast, Nintendo Wii and GameCube.
