Well, i have titled the post as "Common fault to all the themes published in the forum", when i should have added "that i have tried, that is almost all", but it did not fit, i'm sorry. Made this reservation, i continue with the post.
Trying the latest versions of some themes that have been published in the forum i have found something that i think everyone is missing. And i have noticed this little mistake, because my themes also have the same thing, which i am already correcting in the new versions, with a lot of difficulty, by the way.
I will try to explain it as best i can:
Usually, my Attract-Mode have two controls defined to go from one filter to another, for example to switch from All to Favorites (Next Filter) or from Favorites to All (Prev Filter). Well, when i use them in any theme, if there is still no game marked as a favorite, when switching from All to Favorites it does nothing, and everything else remains immovable, just like in the All screen. I think the right thing would be that nothing from any game appeared on the screen and gave me a warning that there are no favorites.
I am not sure if it is an Attract-Mode bug or that the programmers simply have not anticipated this situation. Situation that usually occurs, especially in the first steps with a new system when it has not yet begun to mark games as Favorites.
Maybe it should be the same Attract-Mode who warns that there is no game in Favorites, or in any other filter, but that should be Mickelson who decides. I don't know if i should generate a "bug report" requesting that this be corrected. What do you think? Do i do it or not?
