Graphics
The FM Towns featured video modes ranging from 320×200 to 640×480, with 16 to 32,768 simultaneous colours out of a possible 4096 to 16.7 million (depending on the video mode); most of these video modes had two memory pages, and it allowed the use of up to 1024 sprites of 16×16 pixels each. It also had a built-in font ROM for the display of kanji characters.
One unique feature of the FM Towns system was the ability to overlay different video modes; for example, the 320×200 video with 32,768 colours could be overlaid with a 640×480 mode using 16 colours, which allowed games to combine high-colour graphics with high-resolution kanji text.
