CharPad is a graphics data editing tool that facilitates the production of graphics data in a format compatible with the legendary Commodore 64 home computer.

The program runs on Windows desktop using .NET technology and allows you to design character sets, tiles, fonts and maps for 2D video games and demos.

You can start a project from scratch using the built-in freehand painting tools or import and convert any existing bitmap image into a C64 compatible tile map using various tile sizes from 1 x 1 up to 10 x 10 characters (100 different sizes).

CharPad has been in development since 2003 and has been widely considered an essential weapon in modern C64 game development ever since.

It has also been shown to work well on other platforms using the Mono software for .NET compatibility.

CharPad "Thalamus" Edition is an evolution of the original CharPad tool that contains some useful additional features, most of which have been commissioned by Thalamus Digital Publishing during the latter half of 2019 to assist in the development of their own games.

This special edition is now available to the public.

Looks great, shame I don’t have windows!

Thanks :) you can try running it using Mono or Wine on Linux/Max, I don't use those systems but I know some people have had success with it.
