Hey!
When the tool gets to the patching stage for my portrait mod, this error shows up. (I'm pretty sure I'm using a supported ROM)
When testing it out in DeSmuME, the rom freezes like this after getting the starter.
I'm wondering if I did anything wrong? (I am using wine with .NET framework 4.6.2 on it. I know it isn't supported, but everything seems to work fine) The portraits from said mod are also provided.
