Nowadays playing retro games can be complicated. You not only have to understand the different types of cable and signal, but get your head around video processing, scaling and the difference between progressive scan and interlace if you want to use your classic consoles on a modern TV. While the XRGB Mini might be the answer for those with the budget, many users have to make do with cheaper scalers or by simply connecting their consoles directly to their HDTVs. The 240p test suite was developed by Artemio, initially for the Sega Megadrive and Sega Dreamcast. This software allows you to run various tests on your display and scaling equipment, to find out just how good (or bad) your particular setup is for your retro gear.
Artemio recently ported this useful tool to the Nintendo Wii console. If you have a homebrew enabled Wii (and if not, why not?) you can now run this tool and test 240p, 480i and 480p signals. You can grab the latest version of the suite for all supported platforms here. To find more about the suite or for instructions on how to use it, check out the Wiki here.
