If I recall correctly, someone
was working on a SMRPG expansion at some point, which expanded several options from the original game(More space for text, events, etc.)
He even added a 6th character to the game!
now, where did that project went....no idea but let's hope it was not canceled(maybe it was abandoned long time ago?)

However, there is a talented man that goes by the name darkkefka that has expanded the ROM, somehow. He increased the level cap to 99, which is only possible through expansion. We should ask him.
Even if you "expand" the level cap, you are still limited to the 4MB. The pointers doesn't let you point anything over the 4MB area.
