InfluxDB
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.
I just looked into this for you but no luck I'm afraid. I found the April 2019 fix you refer to but strangely the libretro core documentation still says that saves & states are not supported.
In any case I grabbed todays 'nightly' build from here and updated the core info file from here. The nightly core runs fine on the Mini but while the options for save states do appear in Retroarch, they do not function (saving or loading a state results in an onscreen message that states are not supported).
