Amiga 500
The Amiga 500 (a.k.a. Amiga OCS/ECS a.k.a. Amiga home computer) is a line of personal computers developed by Commodore/Escom/QuikPak. Its first, the Amiga 1000 model was released in 1985.
Early models were released with a Motorola 6800 CPU. These are referred to as the Original ChipSet (OCS). These include:
- Amiga 1000
- Amiga 2000 A-model
- Amiga 500
- Amiga 2000
- Amiga 25001)
- Amiga 1500
The Amiga 500 is the most well-known of the computer line, so far as to skew the perception of the “Amiga home computer line” into being the “Amiga 500 line”, even though it was the third in the family to be released.
Towards the end of the OCS lifespan, newer models with a Motorola 68030 CPU were released. These are referred to as the Enhance ChipSet (ECS). These include:
- Amiga 3000
- Amiga 3000T
- Amiga 3000UX
- Amiga 500+
- Amiga 600
Then the Advanced Graphics Architecture (AGA) models were released, which are considered a separate system in Batocera.
When available, the Amiga 1200 version of a game is usually superior and preferred.
The ECS chipset is capable of switching between PAL/NTSC modes as needed. Outside of that, the ECS chipset didn't offer much enhancement for games, just software, so Batocera really only concerns itself with the Amiga 500.
This system scrapes metadata for the “amiga” group and loads the amiga500 set from the currently selected theme, if available.
Grouped with the “amiga” group of systems.

BIOS
If you're only interested in Amiga 500 games then the only BIOS that's required is kick34005.A500. The rest are if you'd like to emulate specific models/revisions, or need to work around an in-game bug that only affects certain OS versions.

Multi-disk games
Do standard m3u playlists work?
If using a libretro core, it is possible to use a single archive to store multi-disk games. Put the multiple disks in a ZIP archive and add (MD) to its filename. For example, the game Operation Wolf may exist as the following:
roms/amiga500/
├─ Operation Wolf (Disk 1).adf
└─ Operation Wolf (Disk 2).adf
Compress the two disk files into a single ZIP and add (MD) to its filename:
roms/amiga500/
└─ Operation Wolf (MD).zip
├─ Operation Wolf (Disk 1).adf
└─ Operation Wolf (Disk 2).adf
Multi-disc features can then be access from RetroArch's Quick Menu ([HOTKEY] + 
). (
where exactly though?)
