# SteamPlay-Custom When selecting this tool, the *Steam Client* will launch a different program depending on the AppID. ## Configuration You can define the program it launches via the **~/.config/steamcustomrc** file. An example is provided in the **example/** directory. The config syntax is as follows: `appid:application with parameters` In the case of Unreal: `13250:unreal` Each line contains its an appid and a launch command, separated by a `:` symbol. Only the first instance of an AppID is recognized. You can supply as many parameters as you like. If you'd like to enable the *Steam Client* to append its launch parameters to your target as well, append this: `appid:application with parameters`**`:parms`** ## Finding out AppIDs Launch any application in Steam with this tool and you'll get a notification on your desktop. It displays the AppID it is trying to launch. ## History I wrote a handful of compatibility tools that essentially did the same thing: Use the native version of a program or game. This basically just streamlines all my previous tools into one. ## LICENSE CC0
