A mind excercise inside videogames

[Number_21]

Let's suppose that I am a small man into a video game, like a NPC into GTA.
Let's suppose that I am into GTA XII, with a very very advanced AI governing me.
I am a very passionate NPC and I want to understand more about the world that I see everytime that I steal a car and go to a mountain to see the sun and the clouds.
I am living into a simulation, a software, but I am not aware of this. I just want to understand what the light is. So, with all the money that I have, I decide to build a physics laboratory (always inside the world of GTA XII) and investigate the physics of the world I live into.

What do I see? Will I find the same photons that we do all find in the "upper" world?
Do I, at a certain point of my research, find the code that the programmer in the "upper" world wrote?

These are my questions just to practice the brain. Would I find into GTA Advanced Reasearch Labs the same Quarks that we find here?

You would find a "physics" that was far simpler than that of our world in some ways, but more complex in others. You would uncover the source code of the game you were in, and could possibly discover ways to make the game glitch, or even lock up.

The makers of the game would consider this a bug, and try to limit you to the things that make sense in the GTA storyline. It would also be a bug because being able to think those thoughts would consume far more CPU power then any modern system could manage. If it were some future system, then self-aware NPCs would already be understood well enough to prevent you from subverting the purpose of the game.
