MAME Arcade (mame)

for Batocera and Retrobat
Version: 0.265

MAME (originally an acronym of Multiple Arcade Machine Emulator) is a free and open-source emulator designed to recreate the hardware of arcade game systems in software on modern personal computers and other platforms. Its intention is to preserve gaming history by preventing vintage games from being lost or forgotten. It does this by emulating the inner workings of the emulated arcade machines; the ability to actually play the games is considered "a nice side effect". 

Joystiq has listed MAME as an application that every Windows and Mac gamer should have.
The first public MAME release was by Nicola Salmoria on February 5, 1997. It now supports over 7,000 unique games and 10,000 actual ROM image sets, though not all of the games are playable. MESS, an emulator for many video game consoles and computer systems, based on the MAME core, was integrated into MAME in 2015.

The package includes:

4389 games (~190 GB)
628 games in Lite pack (~16 GB)
450 realistic bezels (~2 GB)

Q&A:
1.Q What is Mame 0.265?
1.A This is the latest Mame Romset (Arcade) version for Batocera v40

2.Q What is a non-merged Romset?
2.A Non-merged (a.k.a. reference set): This is the same as full non-merged, however “common” BIOS files shared by a large number of ROMs are separated out to save space. Use this only if you know which BIOS files you'll need for each ROM.

3.Q What version of the MAME emulator does Batocera have?
3.A Batocera v40 uses Mame 0.265 Emulator, Also Batocera has different core's of mame eg: Mame 078Plus And Mame 0.139. Its important to match the Emulator version of MAME with the Romset.

4.Q Does the Romset 0.265 work with Mame Emulator 0.259 Batocera 39
4.A Yes! For 99% of the Roms, there are some new and updated Roms that does not work with backward compatibility but they didn’t work in the previous Romset so you won't miss out anyway :).

5.Q Why not use a merged Romset?
5.A In a merged set Clones are merged into the parent ROM ZIP file, meaning that more than one game is stored per file. This relies on the frontend to select which game is to be played. Batocera does not have this functionality, thus it is not recommended to use this type of set.

6.Q What about RetroBat?
6.A RetroBat 6.3.1 has the mame 0.267 emulator. Mame romset 0.265 will run 99%. We choose to be complatible with Batocera because their supported romset is a older version compared to RetroBat.

7.Q Why are there so many double roms from fbneo compared to mame?
7.A fbneo is a fork of mame, aimed to be more features rich for end users such as RetroAchievements. Fbneo is unable to play disc based games like Killer Instinct. The Goal of MAME is preservation. Mame will support more games and disc based games.
