## On game launch the screen just flashes black and the game won't start, how do I solve this?
This is almost always caused by missing emulator BIOS files which have to be installed separately from ES-DE. See the previous question.
This is almost always caused by either corrupt ROMs/disc images or by missing emulator BIOS files (which have to be installed separately from ES-DE).

## Custom event scripts
There are numerous locations throughout ES-DE where custom scripts will be executed if the option to do so has been enabled in the settings. You'll find the option on the Main menu under `Other settings`. By default it's deactivated so be sure to enable it to use this feature.

The approach is quite straightforward, ES-DE will look for any files inside a script directory that corresponds to the event that is triggered and will then execute all these files.
The approach is quite straightforward, ES-DE will look for any files inside a script directory that corresponds to the event that is triggered and will then execute all these files. There are up to four parameters that will be passed to these scripts, as detailed below:
| Event | Parameters* | Description |
| :----------------------- | :------------------------------------------------- | :-------------------------------------------------------------------------- |
| startup | | Application startup |
| quit | | Application quit/shutdown |
| reboot | | System reboot (quit event triggered as well) |
| poweroff | | System power off (quit event triggered as well) |
| config-changed | | On saving application settings or controller configuration |
| settings-changed | | On saving application settings (config-changed event triggered as well) |
| controls-changed | | On saving controller configuration (config-changed event triggered as well) |
| theme-changed | New theme name, old theme name | When manually changing theme sets in the UI Settings menu |
| game-start | ROM path, game name, system name, system full name | On game launch |
| game-end | ROM path, game name, system name, system full name | On game end (or on application wakeup if running in the background) |
| screensaver-start | _timer_ or _manual_ | Screensaver started via timer or manually |
| screensaver-end | _cancel_ or _game-jump_ or _game-start_ | Screensaver ends via cancellation, jump to game or start/launch of game |
***)** Parameters in _italics_ are literal strings.
We'll go through two examples:
* Creating a log file that will record the start and end time for each game we play, letting us see how much time we spend on retro-gaming
* Changing the system resolution when launching and returning from a game in order to run the emulator at a lower resolution than ES-DE
The following examples are for Unix systems, but it works the same way on macOS (which is also Unix after all), and on Windows (although .bat batch files are then used instead of shell scripts and any spaces in the parameters are not escaped as is the case on Unix).

The events executed when a game starts and ends are named `game-start` and `game-end` respectively. Finding these event names is easily achieved by starting ES-DE with the `--debug` flag. If this is done, all attempts to execute custom event scripts will be logged to es_log.txt, including the event names.
As can be seen in the table above, the events executed when a game starts and ends are named _game-start_ and _game-end_
So let's create the folders for these events in the scripts directory. The location is `~/.emulationstation/scripts`
