I was looking for an editor for golden sun and I came across this, but since I don't know anything about programming I don't know how to use it xd
Do I have to download any program? I want to learn how to use it but I'm new :(

I'm really excited about this tool but can't get it to work! When opening "Editors" using a Golden Sun rom (not TLA) it will crash with this error:
System.IndexOutOfRangeException
HResult=0x80131508
Message=Index was outside the bounds of the array.
Source=gsmagic
StackTrace:

I pulled down the code and I'm trying to run it locally, and it crashes at the same line for the same reason.
It's trying to get a position on the buffer that's out of bounds because the buffer isn't long enough.

for reference:
buffer = byte[8388608], pos = 1532470256

Would love any help! :)
