While most configuration options are accessible from within RetroArch, it’s useful to understand the ArkOS File Manager and the ArkOS file structure if you want to change the settings on standalone emulators.
Unless you’re familiar with SSH, the File Manager is the easiest way to get access to the underlying Linux file system of ArkOS.
The file manager opens up with a split view. Both sides start in the roms directory (which should look familiar to you if you’ve put roms on your SD card with EASYROMS).
The controls are as follows:
Left/Right - Change view panes
Up/Down - Scroll up and down through the list
A - Opens a folder, views or executes a file
B - Go up a directory level (or close the file viewer)
Y - Open the global menu, with various options including Quit
X - Opens a file menu, letting you copy, move, rename, delete etc
Start - Opens the selected folder in the other pane
Select - Multi-select. Select the current item for use with X
L1,R1 - Page up or down
L2,R2,L3,F,etc - Repeat last commandThe current directory is displayed in the top gray bar, and should be /roms in both panes when you open it. If you’re anywhere below the root, the first item in the list will always be “..”, which is a link to the containing directory.
The reason that there are two panes is so that you can move and copy files back and forth. You can use this to move something from the roms folder (which you have easy access to) to the Linux filesystem (which can be more difficult to edit files on).
