RetroDECK Debug Mode

It's possible to enter a "debug mode" the is just flatpak shell in bash.

flatpak run --command=bash net.retrodeck.retrodeck

NOTE: on wayland in some cases it's needed to enter with the command above otherwise some emulators will not run:

flatpak run --command=sh --nosocket=fallback-x11 --socket=x11 net.retrodeck.retrodeck

es-de --debug --home /var/config/

You cam list all the available components via the command:

ls /app/bin

Just type the compoants name directly into the flatpak shell CLI.

Example:

You can also launch specific components by running them, example:

This is useful when for example a game is not starting and you want the output printed in the terminal.

The easiest way is to run the es-de --debug --home /var/config/

Then start or try to start the game or content you want to debug.

ES-DE will spit out two important values.

This tell you the dynamic pathing to the core file + rom file.

Example output of amstrad game being launch via the RetroArch core:

Debug: %EMULATOR_RETROARCH% -L %CORE_RETROARCH%/cap32_libretro.so %ROM%

This tells that the Emulator that is launched is retroarch and the core is cap32 via the selected %ROM%

This is the fullcommand to launch the file

Example output of the game above, a game called Dank Rider:

Info: /app/bin/retroarch -L /app/share/libretro/cores/cap32_libretro.so /home/deck/retrodeck/roms/amstradcpc/1001\ BC\ (1984)(Dank Rider)(fr).zip

If we want to debug a game or content copy and run the full Expanded emulator launch command

Example debugging of Dank Rider:

/app/bin/retroarch -L /app/share/libretro/cores/cap32_libretro.so /home/deck/retrodeck/roms/amstradcpc/1001\ BC\ (1984)(Dank Rider)(fr).zip

This will give you the raw RetroArch output.
