If you do not want to be remodeled, you will encrypt the ROM.
ROM can not be completely prevented from being deciphered, but it can raise the difficulty of remodeling.
However, I hope that when your hack is released, I will release material data used for hacks with a free license.
For example, if you release your data with the license of CC-BY-NC of Creative Commons, the modified FE com-munity will develop further.
Anyone can use this data freely.
However, it is a license that clearly states the author's name of the data, and that it does not use commercial use.
Creative Commons is a free license widely adopted also in wikipedia etc.
You can use it by writing an 8-byte character string called CC-BY-NC.
Also, those who use illegal data of CC-BY-NC will be a barrier to discouraging illegal use, as it will make creative commons to the enemy.
The remodeled FE is built on the analysis techniques of the predecessors.
If possible, please do not forbid and monopolize, but please open it as free data and contribute to remodel FE com-munity, i hope.
