If your roms are already on a Linux/unix/mac, you can use these scrips: https://gist.github.com/ReallyVasiliy/32c33be595408d353e37999ce305ea4d

You need to save each file on the target system, and give them execute permissions (in the terminal, run “chmod a+x move”).

move: moves the roms specified in the file <arg1>, which are contained in directory <arg2>, to a new directory <arg2>/<arg1>. An example terminal command could be:
$ move somewhere/Clones.txt /userdata/roms/fbneo
Will move files specified in Clones.txt from /userdata/roms/fbneo to /userdata/roms/fbneo/Clones

The remove script has the same arguments but simply deletes them permanently instead of moving.

@chizzer thanks for the reply ill give it a shot

Got the catver.ini but still romlister shows no roms when I go through the process of creating the xml.
Seems it's not as straight forward as I first thought.

@dankcushions Great dude. I was working on something similar, I have about 50 configs done, but with artwork on the sides also(for verticals on horizontal). Wow 1500, you must have seperated verticals and wrote a bat file? And yes, I will use these for my long list lol, great place to start. What would be the easiest way to match these file names to my rom files names to seperate? I need like something that will remove all roms that dont have the same name or something. Somekind of match prog
