Its just a raspberry pi running mame most likely. We just need to know what version of mame. It would be something you configure on your end.
From the Arpicade site:
https://arpicade.com/installation-and-configuration-v3-7/Each version of MAME included has it’s strengths and weaknesses, to get the most out of the system a bit of mixing and matching is required.
Mame based:
MAME 0.172: 2nd newest version of MAME included, has the most accurate emulation and can do a few things the others can’t like mirrored cocktail mode & fine adjustments to video output size.
MAME 0.181 Newest version of MAME included, has the most accurate emulation and can do a few things the others can’t like mirrored cocktail mode & fine adjustments to video output size. v0.181 scales differently to all other emulators included.
I recommend using v0.172 over v0.181.
AdvanceMAME: Designed for use with arcade monitors, very configurable – HIGHLY RECOMMENDED for its mix of good speed, options and emulation quality
MAME4all: The fastest version of mame for arm architecture but very old with the most dated emulation, the version on this software is modified to work with the correct scanline output in low res.
*Not recommended for Pi3, the other versions of MAME have much better emulation due to age*
RetroArch:
MAME2003 (Retroarch core): Good speed but a little buggy, improving though – good for mk2 and later Midway titles & SEGA System32 games. Also very good at mapping analog controls to a digital joystick
FBA_Next (Retroarch core): Fast but not as accurate/configurable as mame – good for CPS3 & PGM & a few SHMUPS that are buggy in advmame
Other:
Daphne: Plays laser disc games like Dragons Lair & Space Ace
Additional assorted console emulators
