* More SGD
* WIP, Weather refactor, UI improv
* Rename
* Added 4msps, and fixes
* Fixes
* princeton working
* Renamed proc_weather, bc now multifunctional
* Proto: bett
* FPS_CAME = 4,
FPS_PRASTEL = 5,
FPS_AIRFORCE = 6,
* Came Atomo, fixes
* Separate weather and sgd, bc of baseband size limit
* Fix display
