Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
It can surely be implemented with a GDNative add-on (3.x) or GDExtension (4.0). Someone on the Godot Contributors Chat is looking into integrating doomgeneric with GDNative, so you can play Doom within Godot :)
There is also a 2din3d object in the xrtools I think that allows you to assign a scene via code if you wanted to make a mame machine. https://github.com/GodotVR/godot-xr-tools/wiki/PointerAndUI
