Fujitsu Micro 7
The Fujitsu Micro 7 (FM-7) is a computer developed by Fujitsu. It was released exclusively in Japan and Spain on November 1982, retailing for ¥126,000 Yen ($1,250 USD; $4,216.44 in 2021).
The FM-7 is a stripped down version of the prior FM-8 computer, originally referred to as the “FM-8 Jr.”. It primarily competed with the NEC PC-8801 and the Sharp X1 series of computers.

The only emulator Batocera employs for this system is MAME/MESS's FM-7 core, which is still experimental and lacking documentation. Therefore, emulation of this system can really only be recommended to advanced users.
This system scrapes metadata for the “fm7” group and loads the fm7 set from the currently selected theme, if available.

Emulators
MAME
MAME, the Multiple Arcade Machine Emulator, is a multi-purpose emulation framework which facilitates the emulation of vintage hardware and software. Originally targeting vintage arcade machines, MAME has since absorbed the sister-project MESS (Multi Emulator Super System) to support a wide variety of vintage computers, video game consoles and calculators as well. MAME doesn't use an individual “core” for each system like RetroArch does, instead the ROM itself usually contains the necessary information to accurately emulate it, thus making it specific to the version of MAME it was made for. Overall it's a very complicated subject, we have a guide specific to arcade just for it.
MAME configuration
MAME offers a Menu in-game ([HOTKEY] + 
or [Tab] on the keyboard). This can be used to manually adjust inputs or game settings. If you're having issues with a specific game, check the MAMEdev FAQ for that game here. For MESS systems specifically, you might find more information on MESS's wiki. All options can also be edited by opening the mame.ini file.
