Event Assembler is an event editing tool developed by Nintenlord. It uses assembly-like language to assemble and disassemble events in GBA Fire Emblems. Most of its codes are defined in Language Raws and they can be edited by the users as they see fit without having to edit the program itself. The EA also comes with EA Standard Library, which contains helper definitions and macros that make events easier and faster to make and understand. EA also has some built-in macro's that can't be implemented any other way. EA is programmed in C# using Visual Studio 2010 and it requires .NET 3.5. Whether or not the current version runs on Mono is unknown.
