_Enterprise is a home computer from the 80's, built with a Zilog Z80 processor. It was developed by British company Intelligent Software and marketed by Enterprise Computers, being sold starting with 1985._

_The Enterprise was made in the UK and it spread to other European countries, such as France, Spain and Germany. Perhaps the largest number of machines were to be found in Hungary. Hungarian developers wrote a lot of programs and created hardware extensions. Some machines reached ex-Soviet countries and even Egypt._

NOTE: The Enterprise 128 emulator provides also support for emulating the [Videoton TV Computer](https://en.wikipedia.org/wiki/Videoton_TV-Computer), an 8-bit system based on the Enterprise.

```
/opt/retropie/configs/enterprise/retroarch.cfg
```

The following devices are configured automatically based on the emulated system:

| Emulated machine | User 1 default joypad | User 2 default joypad | User 3 default joypad |
|------------------|-----------------------|-----------------------|-----------------------|
| Enterprise | Internal | External 1 | External 2 |
| TVC | Internal | External 1 | External 2 |

See more details about the emulated joypad and keyboard at <https://docs.libretro.com/library/ep128emu/#joypad>.
