Amstrad CPC

The Amstrad CPC is a computer developed by Amstrad. It was released in 1984.

This system scrapes metadata for the “amstradcpc” group and loads the amstradcpc set from the currently selected theme, if available.

Quick reference

  • Core: libretro: cap32
  • Folder: /userdata/roms/amstradcpc
  • Accepted ROM formats: .dsk, .sna, .tap, .cdt, .voc, .m3u, .zip, .7z

BIOS

No Amstrad CPC emulator in Batocera needs a BIOS file to run.

ROMs

Place your Amstrad CPC ROMs in /userdata/roms/amstradcpc.

Emulators

RetroArch

RetroArch (formerly SSNES), is a ubiquitous frontend that can run multiple “cores”, which are essentially the emulators themselves. The most common cores use the libretro API, so that's why cores run in RetroArch in Batocera are referred to as “libretro: (core name)”. RetroArch aims to unify the feature set of all libretro cores and offer a universal, familiar interface independent of platform.

RetroArch configuration

RetroArch offers a Quick Menu accessed by pressing [HOTKEY] + South button (B SNES) which can be used to alter various things like RetroArch and core options, and controller mapping. Most RetroArch related settings can be altered from Batocera's EmulationStation.

Standardized features available to all libretro cores: amstradcpc.videomode, amstradcpc.ratio, amstradcpc.smooth, amstradcpc.shaders, amstradcpc.pixel_perfect, amstradcpc.decoration, amstradcpc.game_translation

ES setting name batocera.conf_key Description ⇒ ES option key_value
Settings that apply to all cores of this emulator
GRAPHICS API amstradcpc.gfxbackend Choose which graphics API library to use. Vulkan is better, when supported.
⇒ OpenGL opengl, Vulkan vulkan.
AUDIO LATENCY amstradcpc.audio_latency In milliseconds. Can reduce crackling/cutting out.
⇒ 256 256, 192 192, 128 128, 64 64, 32 32, 16 16, 8 8.
THREADED VIDEO amstradcpc.video_threaded Improves performance at the cost of latency and more video stuttering. Use only if full speed cannot be obtained otherwise.
⇒ On true, Off false.

libretro: cap32

libretro: cap32 configuration
ES setting name batocera.conf_key Description ⇒ ES option key_value

CPC MODEL global.cap32_model Choose which Amstrad CPC model to emulate.
⇒ 464 464, 6128 6128, 6128+ 6128+.

Controls

To enable gamepad support, go in RetroArch menu with [HOTKEY] + South button (B SNES), then change Input → User 1 Device type: Retropad to “Amstrad Joystick”.

Here are the default Amstrad CPC's controls shown on a Batocera Retropad:
