Adding Self-Made Games to RecalBox

[Abacaxi]

Hello everyone, I'm new to the recalbox. I got two GPi Case 2W for me and my sister to play with, but I'm trying to figure out how to add my own games to it. I make games (arcade style) for linux mostly using Godot and lutro, but I'm not sure how to port these to the system or if it is even possible to do so. Any help with this would make my day!

Thank you!
