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.
There's also GBARunner2 now which I think generally runs better than TempGBA since it's not fully emulation, the version I linked is compatible with Pokémon Emerald.
