====== Enterprise 64/128 ======
The Enterprise is a Zilog Z80-based home computer announced in 1983, but due to a series of delays, was not commercially available until 1985. It was mostly successful in the UK and Hungary, with its innovative use of custom ASICs for graphics and sound which took workload away from the main CPU.

==== MAME ====
MAME requires the following BIOS files placed in ''/userdata/bios/'':

^ File ^ Description ^
| ''ep64.zip'' | Enterprise 64 BIOS |
| ''ep128.zip'' | Enterprise 128 BIOS |
| ''ep64_exdos.zip'' | Enterprise 64 with EXDOS floppy controller |

===== ROMs =====
Place your Enterprise ROMs in ''/userdata/roms/enterprise''.

<WRAP center round important>
CLK only supports ''.bas'', ''.com'' and ''.zip'' files. Disk and tape formats (''.img'', ''.dsk'', ''.tap'', ''.dtf'', ''.trn'', ''.128'', ''.cas'', ''.cdt'', ''.tzx'') require the ep128emu-core or MAME emulators.

===== Emulators =====
==== CLK ====
[[https://github.com/TomHarte/CLK|CLK aka Clock Signal]] is a multi-system emulator that is focused on low-latency emulation. It emulates Enterprise and a bunch of other old computers. CLK uses RGB video output for Enterprise.

==== RetroArch ====
[[https://docs.libretro.com/|RetroArch]] (formerly SSNES), is a ubiquitous frontend that can run multiple "cores", which are essentially the emulators themselves. The most common cores use the [[https://www.libretro.com/|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]'' + {{:wiki:south.png?nolink&20|South button (B SNES)}} which can be used to alter various things like [[:advanced_retroarch_settings|RetroArch and core options]], and [[:remapping_controls_per_emulator|controller mapping]]. Most RetroArch related settings can be altered from Batocera's EmulationStation.

Standardized features available to all cores of this emulator: ''enterprise.videomode'', ''enterprise.ratio'', ''enterprise.smooth'', ''enterprise.shaders'', ''enterprise.pixel_perfect'', ''enterprise.decoration'', ''enterprise.game_translation''

^ ES setting name ''batocera.conf key'' ^ Description => ES option ''key value'' ^
^ Settings that apply to all cores of this emulator |
| **GRAPHICS BACKEND ''enterprise.gfxbackend''** | Choose your graphics rendering\\ => OpenGL ''opengl'', Vulkan ''vulkan''. |
| **AUDIO LATENCY ''enterprise.audio_latency''** | Audio latency in milliseconds, turn it up if you hear crackles\\ => 256 ''256'', 192 ''192'', 128 ''128'', 64 ''64'', 32 ''32'', 16 ''16'', 8 ''8''. |

=== libretro: ep128emu-core ===
[[https://github.com/libretro/ep128emu-core|ep128emu-core]] is a highly accurate Enterprise 64/128 emulator ported to libretro. It also supports [[systems:tvc|Videoton TVC]] emulation.

== libretro: ep128emu-core configuration ==
^ ES setting name ''batocera.conf key'' ^ Description => ES option ''key value'' ^
^ Settings specific to the ep128emu-core |
| **MAIN THREAD WAIT ''enterprise.ep128emu_wait''** | Main thread wait time in milliseconds\\ => 0 ''0'' (default) through higher values. |
| **HIGH SOUND QUALITY ''enterprise.ep128emu_sdhq''** | Enable high quality sound rendering\\ => On ''1'' (default), Off ''0''. |
| **ACCELERATED SW FRAMEBUFFER ''enterprise.ep128emu_swfb''** | Use accelerated software framebuffer\\ => Off ''0'' (default), On ''1''. |
| **ENABLE RESOLUTION CHANGES ''enterprise.ep128emu_useh''** | Allow dynamic resolution changes (requires restart)\\ => On ''1'' (default), Off ''0''. |
| **BORDER LINES ''enterprise.ep128emu_brds''** | Number of border lines to keep when zooming in\\ => 0 ''0'' (default) through higher values. |
| **SYSTEM ROM VERSION ''enterprise.ep128emu_romv''** | Choose system ROM version (Enterprise only)\\ => Original ''Original'' (default). |
| **ZOOM BUTTON ''enterprise.ep128emu_zoom''** | Assign zoom function to a button\\ => R3 ''R3'' (default). |
| **INFO BUTTON ''enterprise.ep128emu_info''** | Assign info overlay to a button\\ => L3 ''L3'' (default). |
| **AUTOFIRE BUTTON ''enterprise.ep128emu_afbt''** | Select which button gets autofire\\ => None ''None'' (default). |
| **AUTOFIRE REPEAT DELAY ''enterprise.ep128emu_afsp''** | Set autofire repeat delay\\ => 1 ''1'' (default) through higher values. |

=== libretro: MAME ===
[[https://www.mamedev.org/|MAME]] can emulate the Enterprise 128 using the ''ep128'' driver with the EXDOS floppy disk expansion (''-exp exdos'') enabled automatically. This allows loading disk images (''.img'', ''.dsk'') directly.

==== MAME (standalone) ====
The standalone [[https://www.mamedev.org/|MAME]] emulator provides the same ''ep128'' driver with EXDOS support as the libretro core, but as a separate application.

===== Controls =====
Most Enterprise games are played with the keyboard, or need a keyboard to start a game. There is a minimal [[https://wiki.batocera.org/remapping_controls_per_emulator#pad2key|pad2key]] configuration provided that emulates the internal joystick of the Enterprise, but if you use only a joystick, you will most probably have to remap the keyboard to play your game.
