I also write the chronology of the remodeling tool.
2010-2014? Was the age of remodeling with stirling and FE7Edit.
About 2014? ProjectFEGBA appeared and the development environment evolved at a stroke.
In 2017, I made FEBuilderGBA.
stirling is a hex editor that can define structures.
It seems that Westerners do not use it. (Probably because of tool name?)
This is similar to a nightmare2.
However, there is more general versatility.
For ProjectFEGBA (Project_FE_GBA) ,
I explained at FE_Builder_GBA thread, so please search if you are interested.
