Version Differences

 
JP region Forecast Channel
 
Europe region Forecast Channel

Due to cultural differences, the American and European versions of the Forecast Channel show different icons than that found on Japan region consoles. The Japanese icons are more cartoonish, while the America/Europe versions are more phototorealistic representations of various weather conditions.

The icons for all regions can be found in TPLWeather.tpl.LZ.

The Japan region defaults to a 7-day forecast, while other regions receive a 5-day forecast.
