What is CharPad?
CharPad is a graphics data editing tool that can be used to create and edit graphics data in a format that is compatible with the 'character mode' of the classic (1982) Commodore 64 home computer.
It can be used to create and edit a set of character images and the associated data structures (tile sets and maps) that are commonly used to define rectangular arrangements of character images and tiles in 2D video games.
