This tool lets you install songs with Event Assembler instead of Sappy, meaning no more writing down offsets to keep track of your free space.
As with the Sappy method, drag your midi onto mid2agb (not included), and you will get a .s file.
Now drag your .s file onto s2ea, and you will get a .event file. Make sure to keep a copy of
MPlayDefs.event in the same folder as this file.
You will need to open up the .event file and change
voicegroup000 to the location of the instrument map you are using. Alternatively, you may wish to label the Native Instrument Map as voicegroup000.
Here is an example installer:
#ifdef _FE8_ //macro definitions for setting the song table
#define SongTableOffset 0x224470
#define SongTable(index,SongPointer,Group) "ORG SongTableOffset+(8*index); POIN SongPointer; SHORT Group Group"
#incbin "FE8_NI_Map.bin" //now voicegroup000 is your instrument map
#include "my_song.event" //this installs your song
