It does not work on Linux.
You can use wine to run some parts of the program, but the debugger will not work, so your development efficiency will drop considerably.
If you really want to use Linux, please install a VM and install Windows XP or later.
FEBuilderGBA is written in C# 4.0, so you will need an environment that can run it.
