CharSet Lab v1.0

CharSet Lab checks whether a PNG can be drawn on a C64 in character mode and, when it can, builds a ready-to-run .PRG. Drop a 320×200px or 384×272px image painted in a single C64 palette: the tool reports which mode it fits (PETSCII, hires, multicolour, mixed or ECM), how many characters it needs, and lets you export the runnable program.
