240p test suite
A homebrew software suite for video game consoles developed to help in the evaluation of upscalers, upscan converters and line doublers.
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.

Versions
There are currently two platforms that run the suite, both have been developed and tested on real hardware,
- Sega Genesis/ Mega Drive
- Sega Dreamcast
The Sega Genesis version was developed using the [SGDK http://code.google.com/p/sgdk/], it was the first version of the 240p Test Suite and is fully coded in C. In order to run it, we recommend the Tototek Flashcart or the newer Everdrive.
The Sega Dreamcast version includes more options, but the core functionality for 240p is the same. No special hardware or modifications are needed, it will run on any MIL compatible dreamcast after burning the CDI image (discjuggler format).
Source code
The source code will be released at the same time the binaries are, under the GPL. Homebrew and open source SDKs have been used on the platforms so far. The test pattern images used to generate the graphical data for the console versions will be included along with the source code.
