Export Pokémon savegame from Virtual Console to Emulator?

I have put about 3 hours into the beautiful Lazarus Romhack (virtual console edition), and I also have a Retroid Pocket Classic on the way, so I’d like to continue the run on there too.

Is there a way to export the savegame from the virtual console into the mGBA emulator on the Retroid?

These new handheld devices seem like the perfect place to enjoy this hackroms.
