How can I port my game 2D to the *old* 3ds?

[Cresindo]

My game is a very basic 2D game nothing complicated very basic structure and code. I think that an OLD 3DS model would be able to run it with no problem at all.
What I am looking for in this thread is what tools, knowledge or anything related to porting I need to be able to port my game to an OLD 3DS model and what I need to know when attempting to make a port.
I am always open to different ideas to go about porting my game to the old 3ds model!
Some info about the game:
Language: C++
Engine used: Unity

Search for the "Unity for Nintendo 3DS" package on the internet. Frankily, it goes against the rules if I post it here.
