Hello,
Can somebody please help me with the proper way to save configs per core. I have tried different ways but I cannot figure it out. Is there a readme somewhere or set of instructions? I am usually good at this kind of stuff but I cannot get it to work right. I am trying to set up every core so it saves the configs per each core such as screen resolution or is this even possible. I am on version 1.0.0.1 by the way.
Thanks for any assistance 
When you enable per-core configs, it should save a new cfg named for the core in your config directory. It will copy most of the options from whatever your current configuration is, but you should be able to modify it from there. It should load that config whenever you load the core that shares the same name.
I don’t personally use per-core configs, so if any of this inaccurate, anyone is welcome to chime in and correct me
I did manage to get path configs saved per core but I was wondering if anyone has had success with getting screen resolutions beside the standard 640 x 480 to save per core?
No, it’s not currently supported and it can’t be manually written to the config either. This is actually quite frustrating with the SNES core, because core aspect ratio is incorrect and 512*448 doesn’t save either.
