Feature Request: Custom Instalation path

For those who has two discs on ChimeraOS it would be better to have an ability to define custom installation path for roms, epic-store games, etc.

My suggestion would be to have in System tab an input for entering path to specific folder where everything will be located.

Start by locating the System tab and the code that handles paths for ROMs and Epic Store games. Determine how a user-selected installation folder should apply to each requested content type; done means the path can be configured there and is consistently used for new installations.
