well I think what happened is this:
-the game cartridge is damaged and luckily only a part that affects the graphics of the game is affected
-so the textures that are used to make the plants look snow-covered are damaged, everytime the plants need to look like that, they show up glitched and weird instead
-it's only the graphics, so the way they function isn't affected at all
-if i went to another town that's in winter, the plants there would also probably be messed up too, because my game doesnt have the right textures to show
-the actual game save data is the same as normal, but the way some objects show up to my game cartridge is weird
so i think that it should work just fine to actually use, but it looks weird, but only to me. ... does anybody have a dream address set during winter time i can visit to see how it looks?
