That would be great since there are some true hidden gems playable on this "platform".
I tried the packages for Retropie. They work, but the sound is faulty and I just prefer Recalbox.

Did somebody get the Rpg-Maker to work and is willing to share his or her knowledge?

Thanks a lot. This solved the Problem.

I ised the 8bitdo Controller for quite a time without any issues. This started suddenly, after reconnecting it.
Maybe it's just a faulty device, bit even then, the Bug is quite strange...

@scavy I'm using the SF30 Pro
I haven't tested other BT-Controllers yet. I'm just wondering if I'm the only one with these issue...

I´ve got an interesting issue here. Everything works fine, as long as I´m using Joypads without Bluetooth.
As soon as I´m connecting my 8bitdo Controller via BT it takes about one Minute to start a Game. Everything else still works fine. The Menu wokrs well and the Games run without any lag. The only problem comes, when I´m starting a Game. The Screen goes Black for about one Minute, after that the Game starts and works normal.
To make things really complicated: This problem doesn´t effect Dreamcast Games. When I´m restarting EmulationStation withour connecting my BT Gamepad, everything is fine again and the Games start in an instant.

Does anybody know the reason for this, or even better: can provide a solution?

already did that. Thanks for the help. ;)

So, Thema wurde gelöst. Ich hatte die Spieldateien falsch sortiert. Bislang hatte ich einen Ordner mit Spielenamen, in dem die Dateien drin waren. In diesem Ordner hatte ich einen leeren Ordner namens "spielekürzel".scummvm
Ich hatte das wegen dieser Anleitung so sortiert:

Bei der letzten Recalboxversion lief das auch. Jetzt habe ich allerdings den Tipp bekommen (Danke an @abunille und @Substring ) dass direkt in den Scummvm-Ordner ein Ordner mit dem Namen "Spielekürzel".scummvm rein muss. In DIESEN Ordner müssen die Spieldateien zuzüglich einer leeren Datei namens "Spielekürzel" mit der Endung *.scummvm (Also Quasi ein Ordner "Spielekürzel".scummvm darin die Spieldateien + eine Datei namens "Spielekürzel".scummvm)

Das Ganze funktioniert wunderbar und vielleicht ist damit auch dem Themenstarter geholfen. @baphomet

Okay I just tried the way @abunille promoted and it worked perfectly.
Case solved, thanks a lot.
But the Way my files were organised did work with version 4.0.1, but I don´t have any idea why...

And here´s an image of the files.
