The version 1.0.0.01 it's currently upstream/wip, which it's the one that it's currently been used by retroarch\libretro\retropie.
The stable emulator, version 1.0.0.0 can be found in it's official repository: Or through standalone emulator (Misc -> Generate Dat File). There are 2 ways to get the DAT files, one through the libretro port: No worries about getting those files, all bios are already included on the confused about your comment, none of the file listed here have any kind of take some time to apply the changes, here it's the direct link: 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. 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
