Final Fantasy VI - day/night cycle (hack)

Ronhack by Madsiur.

Release: 11/03/2018

This is a complete day / night cycle that works everywhere you want: on regular map, on world maps and during world map events or mode 7. The battle backgrounds can also reflect the time of the day.

The game goes through a day or night then will gradually switch to day or night by tinting the screen toward blue or the opposite. The day length is customizable as well as the number of color transitions, thought the default 9 is kinda optimal. You can also customize the length of a single transition. There is also the option to have a set of predefined night palettes instead of global palette tint but this feature has not been tested due to the lack of proper palette
