I'm from Brazil and I totally understand why there is so few games in Brazil's Game Section of the Marketplace. I agree with Nudua, it's a pain in the a$$ for the developer to submit a game here with all that bureaucracy required.
But as a consumer from Brazil, I have to thank a lot Samuel Blanchard for submitting the Purple Cherry as an App and not as a Game, this is the only fast and easy way for us here to get the games without a lot of pain for the developer.
I know that it's much more cool to have the game in the Xbox game Hub, but I prefer have the game out of the Xbox hub than not have the game at all!
Samuel Blanchard, thanks for supporting Brazil, I was one of the buyers of Purple Cherry from here and will soon buy blue tomato also. :4 )
Nudua, I have already played with your emulator using a student developer account and the Phone7Market program found here in XDA and it is great! I'm sure people here in Brazil will love to play your NES emulator also, if you put a version of it in the app section too. NES is very popular here.
