I can add and play a game. It will remain as long as the session for Magicbox is up. When I reboot Magicbox, it is all gone. I will try the version on the huawei store. Thank you for the reply!
An idea for a work around, I use an emulator frontend on Android called Launchbox. It has been a good workaround for launching roms on the SD card to an emulator (usually retroarch). It supports adding custom emulators to pass the game file to. It asks for the following for the following fields when adding a custom emulator:
Custom Emulator Package Name
Custom Emulator Activity Name
Custom Emulator Rom Path Key
Is there any Magicbox documentation that states what some of these items could be?
Thanks Again!
