Its really great how we can breathe new life into older games like this. I'm currently working solo on a Tales of Symphonia gamecube decomp. My aim is to let AI do everything of substance. currently about 3400 functions are exact out of about 4800. So still a way to go. But I haven't written a single line yet.
How did you get started? I have a project in mind and would love to try, but getting a foothold on it feels really hard when you are starting with an ISO image and an empty folder.
