I just used tilestudio to create a test map.
Here is a script that will output defb assembly for your maps.
It doesn't output map width/height because it assumes all will be the same.
Also it outputs 1 byte per tile.
It doesn't output the tile gfx, these are best in a seperate file.
Perhaps someone else will find it useful?
Copy this into the same dir as tilestudio, select "cpc" in output type and generate output.
