Funny that they show separate in Wiiflow...SGp1 and gp2 have same id so unless i do the kernel offset checks there is no way of telling.Besides the theme in repository can be used with both gp games.
As for your submission i dont see a colosseum there. And they all have gamelogo so at best i ll use some of them as splashes
Not sure what you mean by "As for your submission i dont see a colosseum there."
Is there a problem with game logos?
I personally prefer splashes to loading screens. Similar to Wii U games.
