240p Test Suite for Dreamcast 2.02

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 signals. The Wii, Dreamcast and GameCube versions have modes for 480i, 288p, 576i and 480p evaluation as well.

It consists of 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, PVMs, BVMs and Arcade monitors via RGB.

As a secondary target, the suite aims to provide tools for calibrating colors, geometry, linearity, overscan and black & white levels, for specific console outputs and setups.

MDFourier is also a part of the 240p Test Suite, it can compare audio signatures and generate a series of graphs that show how they differ. These can help to identify how audio signatures vary between systems, to detect if the audio signals are modified by audio equipment, to find if modifications resulted in audible changes, to help tune emulators, FPGA implementations or mods, etc.

This software is open source and free, but your contribution is welcome. Thank you for using the 240p Test Suite.
