RetroPie Operating System

SPECIAL CASE: MAME [ARCADE ROMS]:
The MAME emulation system also allows the emulation of arcade machines. The difference
to normal consoles is that the games/software in gaming machines are not contained in
individual elements such as cartridges/floppy disks/CDs, but are distributed over several
chips in the machine. In order to simulate a certain machine, a complete set of
"dumps" (English binary copy) of all chips must be available. If you do not read out a
gaming machine yourself, but obtain the data from other sources, you will come across the
term "Romset". This term has become established as a description of a summary of several
ROM files: To save storage space, it is possible that not all required chip copies are
contained in one ROM file - since the chips installed in gaming machines can also be the
same across several machine families, only a single copy of the corresponding repeatedly
appearing chip is made available in one ROM set.
This is the reason why it may occur that ROM files cannot be played back by the emulator -
some ROM sources only offer incomplete ROM files. If you do not read the respective game
machine yourself, we recommend that you read the documentation of the respective ROM
source-this usually shows how an incomplete ROM file can be completed.
The arcade emulators used in RetroPie are prepared for different "Rome sets". You can find
a list of the rosets for which the respective emulator works and thus into which folder the
ROM files must be copied in the RetroPie documentation under:
