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.
On the darker setting for the color bars pattern (00-1F) Red and Blue bars are swapped. Confirmed only with the Wii version, unsure about other builds. Screenshot from an emulator as I was unable to get a decent photo.
