BitS: Pick Axe Pete Level editor

In the editor you load a Pick Axe Pete ROM and it tells you which game version it is. Then you can zoom in/out on the interface, and draw lines on the level by click/dragging on the grid area. You can also select a level to edit using the numbers on your keyboard, and then save as a different file.

When saving it keeps the same CRC32 hash by editing a section of unused zeroes in the ROM so that O2em can still recognize which game it is. This was a hassle to achieve and I had to resort to help from the community, especially Catan from GMS2 forums, who actually provided a working script to do that calculation.

"Bread in the sky" translates to "pão no céu", a little joke about the localization this game got in Brazil. Fortunately, its acronym is BITS.
