Create modified genre XML files for MAME

[Takaji]

I've tailored my MAME collection and have deleted unwanted roms, such as clones/not working/mature/mahjong and so on. What I would like to do is:

1. Create a modified MAME.xml database containing only the roms present in my roms directory with the relevant metadata (manufacturer, year of release, etc.).

2. Create modified genre sub-databases containing only the titles present in my custom MAME.xml database.

Is there an easy way to do this? I've been playing around with certain programs but it all seems a bit confusing at the moment. I should be able to start out with the official MAME.xml database from Hyperlist and go from there...?

Thanks for the help!

I'm new here Takaji so take that into consideration. That said I'm sure one of the more senior members will correct me if I'm off track.

I used Don's HyperTools - more specifically HyperSpin List Generator to do similar to what you described.

Originally I had around 9.5k v.156 working roms and removed clones, mahjong, etc. I created a new .xml and simply renamed the old to retain it, and named the new one mame.xml

There's a good youtube vid here if you get lost -

Hope this helps.

That's great, thanks! The only problem I see is that the CHD column doesn't seem to update with "Yes" ever. I've got a bunch of chd folders located in my roms folder, but nothing shows. Any suggestions?
