Arcade/Mame gamelist xml location?

  • Hey all,

    Sorry for the newbie question, but i've dug through the wiki and I can't find a clear answer.

    Running RetroPie 4.2 on Raspberry Pi 3. I've loaded and am running all of my roms from a USB stick. But the Arcade(running Mame2003) game list is an ugly mess with thousands of ._ file names before the first real roms are listed. I'm trying to configure an xml list to filter them out. I am familiar with setting this up in standalone MAME, but I haven't figured it out in RetroPie yet so any help would be much appreciated.

    I've downloaded the MAME 0.78u5 'Lite' DAT File from here: but I'm not sure where I need to place it and what it needs to be named. If anyone can point me in the right direction I would be very grateful.

    Removing all those Mac ._ files should make the listings disappear as well. To do that, enter the following into the command line.

    find /home/pi/RetroPie -name "._*" -exec rm -rf {} \;

    To prevent this from happening again, avoid copying any files over using the OSX Finder.

  • thanks mediamogul,that helped alot. I'm still can't figure out where to put this xml file though... :( I ideally would like to make an xml list of maybe 300-400 games. But I need to get my bearings first

    Those DAT files are used to validate and rebuild certain ROM sets. All the information you need regarding that process can be found here.

  • ah okay, I assumed the Dat/xml file worked as the filter. Hyperspin/Rocketlauncher are set up in that fashion, you can edit the XML file to show or hide games, (My Arcade Cabinet runs on that system, but I'm wanting to try new things here) I guess I assumed tooooo much.

    Thank you for your help!
