Hi, I am new here and have a query, I downloaded the Rom pack of NES games (trying to set up a retro pie) once I extracted the file I noticed there was numerous games that had more than one ROM, for example there are 9 copies of "baltron" each with different names "baltron [b1], baltron [b2]" and so on.
I was just wondering is there any differences in these, why do I have so many copies and whats the best ones to use.
Sorry for the ignorance and thanks in advance
You downloaded a romset sorted with GoodTools. GoodTools sets contain every known dump just because they can. [b] files are bad dumps, almost certainly you don't want those. You should get the [!] files, or failing the verified dumps pick the ones without any codes aside from the region code. Here's a list of what all the codes mean:

Picking out all the files you'd like individually is a major pain in the ass, you can just run GoodNES over your romset and have it sort the different filetypes into different folders so you can easily delete the batches you don't want. It's a DOS program though, so you need a basic understanding of DOS or you need to find a frontend that works on your OS.
Awesome, thank you so much for the response :)
I wouldnt have a clue how to start with the DOS so it looks like ill be going through them and picking individually
Don't do that manually before at least Googling for a frontend. By frontend I mean a small program that will run the DOS program for you, they're normally pretty basic and easy to use, just a small popup with checkboxes and pulldowns that'll let you enter the commands you want to execute.
Personally I have no interest in having every single hack mod bad dump ect ect
But sorting manual roms manually is not needed
Rom auditing tools like clrmamepro and Romcenter are a must though best for no-intro sets that cover all the official games and mostly just contain good rom dumps
clrmamepro is a more accurate audit tool but Romcenter is more user friendly and can even be used as a front end
If I was going to go down that road again I would still use clrmamepro as the audit tool and Romcenter to look through the roms apply filters ect ect to find what I was looking for while still keeping a full set of games, this even comes in handy if you use flash kits and just direct romcenter to 7-zip instead of an emulator
I'm not 100% sure if those support good tools or not it's been a while but was sure one or both did though or had dat files based on good tool rom sets, it's been even longer since I delved into good sets.
