Hello again!
Sorry for the lengthy comment, but I really want to fix this because I really want this to work!
Using the Beta 27 of the New Super Ultimate Injector, the Rom Save Type is set permanently to unknown:
So, I tried GBA Tool Advance to patch it, and apparently, it doesn't have a Save Type...
And because of that (I think), I can't seem to patch it.
And using VisualBoyAdvance-M, it doesn't generate a save file too after I opened the game for a minute to play it, and unfortunately, it doesn't save it.
Again, sorry for the lengthy comment.
Any ideas? Any help is appreciated!
