@ -533,6 +537,8 @@ The following variables are expanded by ES for the `command` tag:
|
|||
|
||||
`%EMUPATH%` - Replaced with the path to the emulator binary. This is expanded either using the PATH environmental variable of the operating system, or if an absolute emulator path is defined, this will be used instead. This variable is mostly useful to define the emulator core path for Windows, as this operating system does not have a standardized program installation directory structure.
|
||||
|
||||
`%ESPATH%` - Replaced with the path to the EmulationStation binary. Mostly useful for portable emulator installations, for example on a USB memory stick.
|
||||
|
||||
For the `path` tag, the following variable is expanded by ES:
|
||||
|
||||
`%ROMPATH%` - Replaced with the path defined for the setting ROMDirectory in `es_settings.cfg`.
