Looked at Fatmatch, this one seems handle probs very well.Are you familiar with Fatmatch app (attached below) for renaming?
I personally would just match the Japan Mega Drive .png art to your rom names.
Then I always use Advanced Renamer (Freeware) to add .zip extension to the cover art .png files. If you have never used Advanced Renamer, there is a slight learning curve but not difficult, once you use it a few times, you will never use anything else.![]()
For renaming or replacing I have scripts on my file manager (linux), I use a very nice directory comparator called meld on linux too.
How to set boxcovers layouts per system ? When I change one others are impacted.
EDIT : ok it's "locking sourceflow" in the settings option. I had a différent understanding of that option.
