### RetroArch custom Aspect Ratio override When using the "custom" aspect ratio value in **ADVANCED SETTINGS > GAME ASPECT RATIO**, it is possible to force the value of the ratio to apply in RetroArch by creating a .txt file with the following information: * width * height * top * left The information from the file will automatically fill the following values in RetroArch:
To do so, create a txt file either in the `roms\` folder of the system the ratio needs to be applied, or within the `user\customratio` folder of your RetroBat installation:

Example for NES

The file must be named either: * `__customratio.txt` (to be applied for a specific game) * `_customratio.txt` (to be applied for the full system) Finally, enable the "custom" aspect ratio value in RetroBat:
