I have been playing pokemon leaf green for a while with the "Sub circuit m-1" error. Later on, I figured that it could be fixed by patching the rom. Now I have the patched rom with working in-game saves. But it only works if I start the whole game over at the beginning.
So is there a way I could import the old save-state save to the new patched game? I can load the old save-state in the new patched rom but it won't let me save in-game it only gives me the error: "Save error. Please exchange backup memory."
