Add Games To Gameboy Emulator Software Renderer Are

Creating a minecraft clone, a game engine and a software renderer are some of the items sharing the list with create an emulator.

After some talks with my good friend Kleverson at the office, he convinced me to make a Gameboy emulator.

Its not as complex as other game consoles from that time, but its definitely not trivial.

Learning computer organization in practice, get more familiar with assembly language (not a specific dialect, but whole low-level concept), understand how primitive graphics systems worked, improve my debug techniques, and end up with working project.

You can realize by now that Im selling the idea of creating an emulator, so grab a coffee and lets do this together.

Its not even close to be functional, it only runs the bios software so far and Im currently working to make Tetris run on it.

I really recommend you reading other projects codes, that can give you insights on how to do specific things.

It should run on Windows and Linux from the beginning, even though I mostly work on it on Windows with Visual Studio.

The only 3rd-party library Im using is SDL for the graphics, but we dont need this right now.

An 8-bit CPU (4MHz) based on the Intel 8080, 8kB RAM and 8kB VRAM.

Its very important to read the Wikipedia entry for the Gameboy and watch this amazing video before continuing this article.

You know that an emulator emulates, but emulates what Every electronic component What are the components Do I need to understand the target platform from the physical level.

You dont have to implement things exactly the way they are, no need for wires or electric pulses.

Remember the goal is to run a program that was made for that architecture and the results should be pretty much similar, but the way you do does not matter.

Since everything relies on the memory mapping, thats what we are going to do first.

But they can be accessed in pairs, for instance A, F, B, C, H, and L registers can be accessed with the combination AF, BC, and HL.

So we have 16 bit addressable memory, going from 0x0000 to 0xFFFF, that means we have 65,536 positions.

As mentioned previously, gameboy uses the memory as a bridge between CPU and other components.

So this memory has regions that access data from the ROM, the cartridge, video memory, sound, etc.

When the gameboy starts, the MMU will map it in the first 256 bytes of the memory, so thats why we need the finishedbios flag.
