I like this one, very intense number of spaces! Has it been working well for you? It is interesting how the game never used more than 256 (8bit) indices for spaces, yet they reserved shorts (16bit) for the space indices everywhere, so something like this is possible.
Have you tried the Screenshot feature at the top of PP64? I made it so that screenshots can easily be shared of boards, and I think it is easier to view than the in-game screenshots. (Although when boards are uploaded to the Downloads it is good to see both kinds of screenshots.)
Overall thanks for using the editor so much, it is fun to see the different boards!
