playcode.zip	playcode v1.0	Generate VCS2600 playfield graphics

Purpose of the program
'Draw' playfield graphics with Excel-sheet or text editor and convert
it to data statements for use with dasm assembler.

No special requirements needed. Of course, to make bin file, one will
need the dasm assembler. To try the bin file use a 2600 emulator (or
program a eprom and insert this as a module in the vcs2600).
