clrmame Discussion / Re: [BUG] clrmamepro-generated 1G1R ROM sets missing ROMs or selecting wrong region
« on: 08 March 2020, 21:11 »I haven't looked into the actual score but I could imagine that both USA sets (the demo and the normal one) might get the same score value and then maybe the last one is prefered for no real reason. I guess the algorithm was more for a scenario where you only got distinct regions within one parent/clone relationship.
Well, I think my own algorithm has reached a point where I can say it's able to achieve a pretty good 1G1R set, as long as the No-Intro naming convention is used.
I have refined it with the help of some users and I think it's safe to say it works.
At the moment, it's only present as the Python script I linked in the original post for this thread.
Here's some tutorial of usage, if you're interested: https://www.reddit.com/r/RetroPie/comments/f5b2gb/how_to_make_1g1r_rom_sets_using_nointro_dats/
(Yes, the title is a bit provocative on purpose

Of course, generating 1G1R sets is all it does, but it may be worth trying it and seeing if you think something like this could eventually be implemented in ClrMamePro itself.
