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.
Then you'll need to update. 1.7.3 is very old, like 2018 old. Support for mapping multiple controllers to a single input device was merged in 2021 for 1.9.6 and we are currently using 1.15.0.
Since your version is from before the switch from Stretch to Buster with RetroPie 4.6 in 2020, unfortunately you'll not be able to upgrade in-place. You will need to backup and reinstall.
