Personally I use the UniBIO S4.0, that way I can switch to AES or MVS on-the-fly. Upload in process, please be in the way, I only re-upload this set after each MAME sync, which in this month just did happen yesterday ( ), so the new set will be on in the next couple of days there, rebuilding the ROM set to full non-merged will work with any upstream finalburn neo port, you can switch the MVS and AES mode by choosing the proper bios in the fbneo options.

Retroarch thumbnails only works if you import the ROMs by using the DAT file, the guide its in the follow now everything updated until the current date not a batocera user, from what I know, it uses the fbneo libretro core, maybe you can try to find a way to update it, and after that rebuild your ROM set with this DAT files: Killer Instinct 1 and 2 ROMs and HDDs were moved to the debug set due to emulation issues, it might be added to the standard build when those problems get Pavel
