Description:

Groen is a level editor for NES Bionic Commando and “Top Secret - Hitler no Fukkatsu” (the Japanese version of Bionic Commando which BC was based on). It can currently edit a level’s physical layout, palette, tile allocation, and unit placement. Plus you can change which music is loaded for each room. Level editing is programmed so that you can modify the level as a matrix of 16 x 16 pixel blocks. In reality the game uses 32 x 32 pixel meta-tiles to describe each screen, but the editor converts to that format from the editor’s format.

Groen now also has a graphical editor for the game’s main map, and a window for setting certain variables specific to each Area.

It is programmed in Visual C++ 6.0 with MFC and some parts in X86 assembly. The source code can be found in a subfolder and you are free to use it for any purpose.

Instructions for how to use the editor with the Japanese ROM is found in the readme.
