Hey Dirbaio:

Is there a way that I can add a line of 8x8 blocks to the Nohara set? I would like to add more custom blocks to it, but don't know how to add lines for more graphics... (Brick containing Mini-Mushroom ) I know how to code the new block (thanks to you )

Does Nohara have any compression? If so, what happens if you use the same type of compression on Jyotyu?

Just an idea...

no... that wont work.
All graphics of all tilesets are lz77 compressed. That's not the problem, since we know how to recompress them.
The problem is with the behaviors. All behaviors of tilesets 1 and 2 are plain files, not compressed. BUT tileset 0's behaviors are inserted in the binaries (executable code), which are compressed with the weird compression that we can't break yet.

I thought you guys made the code, not rip it from the game...

Is there a way to edit every frame of the "animated" blocks? Like the bricks are in Jyotyu (but make my own in Tileset 00 - Grassland)?

That doesn't work either.

I extracted absolutely everything included in the ZIP file to the same folder, including spritedata.txt
