@SpudsMcToole I wonder if you get the same results by using content_directory="/home/pi/RetroPie/roms/x68000/ That might be something worth setting for disc based games.

Thanks, that's exactly what I ended up doing. I had hesitated with UXS for a while because I never thought I could get it to work.. turns out it was just generating the xml in a directory/folder I wasn't expecting. Thanks

@supercatfooz Update: I just found an HDF file that seems to work fine, making the two .dim files I have obsolete. I'd still like to know if multi-disk mounting is possible for the future, though! (plus it'll help whoever else happens to have this problem)

@Pyjamarama You can save your controller settings for that game or across the whole core. Those options are in the control menu in the hotkey+X retroArch menu, right above where you edit the control inputs.

That's a shame. I was hoping it was something I could fix on my own. I do love my Japanese computers. I'm glad to see that an official Retropie guide for the PC-88 emulator showed up within the past few months at least.

In the moment there is only a pull request in es-theme-carbon. You must wait until it will be merged. If you want to try it you can copy the folder "x68000" from https://github.com/RetroPie/es-theme-carbon/tree/3ff4d1f136a8e2eacc44fb71aa0abaa36ed94865 to "/etc/emulationstation/themes/carbon". I haven't tried it until now.
