There is a Very High Likelyhood this mod will not Update to 2.0
Last Update was 3 Years Ago.
And this mod is the most recently updated Mod of all his mods
By what they are doing on github, They have Moved on,
They are now working on a Lib called AD53xx_library that is a C++ Arduino library for DAC series Chips
In short this person has most likely moved away from games to begin to work with Computer Chips IRL (Most likely their job now)
Basically 1.1 is basically the last ever version of this mod until someone Forks it with an update or they update it after 3 Years to 2.0.
