Game and watch : Games won't run

[Xefir]

Hello

In the last version of RetroDECK, Game and watch game can not be run because of an error on Retro Arch.
Here is the log :

The crash happens on Steam Deck and Linux desktop as well.

Hope it can be useful.
Have a nice day.

Can you try to reset RetroArch from the RetroDECK Configurator (not from the emulator itself).
Be aware that this will wipe any custom configs done not in the Configurator itself.

If this doesn't help I would try to test the same game on the official Retroarch Flatpak.

I would even test other games in the same way.

[Xefir]

Hello again.

I only use the official flatpak. I don't know how to install retrodeck by any other way.

To get the log, I follow this guide : https://retrodeck.readthedocs.io/en/latest/wiki_development/general/debug-mode/

The problem persist if I uninstall the flatpak, use the --delete-data parameters to clear the app datas ans reinstall from scratch (via flatpak).
I hope this information can help you.

Thank you.

He meant install RetroArch flatpak and see if it has the same issue as within RetroDECK.

Just search for RetroArch on flathub and put one "game and watch" rom there and try to launch it.

[Xefir]

Oh sorry for the misunderstanding.

If I install the official RetroArch flatpak, it works, but it use the gw_libretro core instead of the mame_libretro that retrodeck automatically choose for running the game.

If I run the retroarch graphically inside retrodeck and running the game manually, it also boot with gw_libretro core and run fine.

So this is only when running the game through emulator station that it fails to choose the right core.

Fixed by defaulting gw_libretro, fix in 0.8.1b
