What type of game intense we are going to use. 

It's my first game jam so can you please help me? 

I am not familiar with the phrase "game intense", do you mean "game engine"?

Just to make sure you are aware, this competition is about making software that can run on actual game boy hardware. You will want to review the rules and requirements to make sure you understand the requirements for entries that are submitted. That page also has links to tools and documentation which can be used.

There's GB Studio and ZGB for valid Game Boy game engines.
