We're going to come up with a full set of rules in the next couple days.
I don't know if we'll have splash screens, I don't like those personally. But we'll see.
The idea of the homebrew bounty is to encourage homebrew development.
It is NOT to focus all attention on gbatemp, or on the competition in particular.
I guess we could have an optional splash screen, but it shouldn't get in the way of developers that don't want it.
Can't find any threads about this particular issue on GBAtemp or the wider intarwebz. Saw one video on YouTube that seemed relevant, but it was some dude with the same issue, no solutions offered in the comments. :/
