# Emulator
![emulator](emulator.jpg)
1. [build](build.md) the emulator
2. run `emu.sh`
3. to use [bridge](https://github.com/trezor/trezord-go) with the emulator support, start it with `trezord -e 21324`
## Profiles
To run emulator with different flash and sdcard files set the environment
variable **TREZOR_PROFILE** like so:
```sh
TREZOR_PROFILE=foobar ./emu.sh
```
This will create a profile directory in your home ``` ~/.trezoremu/foobar```
containing emulator run files.
Alternatively you can set a full path like so:
```sh
TREZOR_PROFILE=/var/tmp/foobar ./emu.sh
```
When the **TREZOR_PROFILE** is not set the default is ```/var/tmp``` .
