This only happens with MAME current core and it’s the weirdest bug i ever come across.
The only thing i done was to copy-paste my RetroArch setup to a USB flash drive, along with some systems, to make a portable setup. I didn’t change any settings other than a few directories.
When running MAME from the original directory, the Save/Load functions are there. But when i run the same core, with the same RA version, using the same exact settings and the same exact rom from the USB, those functions don’t appear in the menu in the same way they don’t appear for cores where those functions don’t work.
This happens only with MAME, the other cores don’t have this problem.
I simply cannot figure out what happens here
