Some time ago I created a list of things I wanted to do as a programmer. 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. It's not as complex as other game consoles from that time, but it's definitely not trivial.

I got motivated because I saw all the potential subjects I would be exposed while doing this. Full keyboard notes. 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 I'm selling the idea of creating an emulator, so grab a coffee and let's do this together.
So, let's say you've set up a Game Boy Advance emulator Hack #44 and begun to delve into enjoying the fruits of the vibrant GBA homebrew scene. But playing these games on your PC monitor just isn't enough—isn't there some way to get them from there onto the GBA SP sitting on your desk?

Repository mygbemu is already live on GitHub and you can check the code here. It's not even close to be functional, it only runs the bios software so far and I'm currently working to make Tetris run on it. You'll see more in this project as I write the posts.
Environment and Setting
There are a lot of open-source gameboy emulators on GitHub, written in all languages you can imagine. From Javascript to Kotlin, C++, and so on. I really recommend you reading other project's codes, that can give you insights on how to do specific things.

I decided to use C because I wanted to get more familiar with it, since I hadn't coded in C for a long time. 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 I'm using is SDL for the graphics, but we don't need this right now.
The Gameboy
The first version of the gameboy was released in 1989 and was based on a hardware from almost 15 years before. An 8-bit CPU (4MHz) based on the Intel 8080, 8kB RAM and 8kB VRAM. It's very important to read the Wikipedia entry for the Gameboy and watch this amazing video before continuing this article.
Where to start?
That's the question my programming friends ask me when I say I'm working on an emulator. And I did that myself. 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?
Well, first we need to understand that 'emulation' is not 'simulation'. You don't 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. For instance, the console uses a memory mapping as a bridge to connect the 'video card' to the cpu, but you can make a direct call from your cpu module to the video, if the outcome is the same, you're doing it right.
We have many components we need to emulate, mostly important the Memory, CPU, Video Unit and Sound Unit. This also is the order that we are going to implement. Since everything relies on the memory mapping, that's what we are going to do first.
Memory Management Unit
First thing we need to know is that since gameboy's CPU is 8bit, its registers can only hold 8 bits of data at a time. 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. The PC and SP are 16 bit only registers. So we have 16 bit addressable memory, going from 0x0000 to 0xFFFF, that means we have 65,536 positions. However, it's not all RAM memory or anything. 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.
This is an accurate map of the gameboy's MMU from this page, which I recommend you to visit to gather more information about each area.
Imovie montage effects. Jumping to the code, we can just define our memory management, basically following the areas:
bioswill store the 256 bytes startup code. When the gameboy starts, the MMU will map it in the first 256 bytes of the memory, so that's why we need thefinished_biosflag. And it's a pointer because it needs to be initialized pointed to position0xFF50.addris the complete addressable memory, so it's really easy to write and read from it- the're in a union because we can also directly access each fraction of the MMU
Let's initialize (and destroy) our MMU:
Now we need to write basic read/write functions:
These functions will read and write 8 bit values, but since our CPU can work with 16 bit values, our MMU also needs to be able to read and write these values:
Now we can play a little bit with this code. Read and write both 8 and 16 bit values to our MMU.
My usb is not showing. Let's also load the bios code:
You can also check the complete assembly for this code here. It's gonna be very important once we start the CPU.
Can you believe our MMU is basically done? I mean it does almost everything the CPU needs, so we can move on to it. But before, let's play a little:
You can check the final code at GitHub. It's a bit different, but that's because I'm going by steps.
Next time we will be looking at the CPU.

A Brief Introduction to GBA (Game Boy Advance)
Game Boy Advance, referred to as GBA, is the second-generation portable game console released by Nintendo on March 21, 2001. It is backward compatible with the previous-generation Game Boy games. The biggest feature is the use of a color TFT LCD screen.
The GBA has two revised models, namely the GBA SP which was launched in 2003 and the GBM which was launched in 2005. Although GBA has been delisted for a long time now, we can still relive those classic unforgettable GBA games through the GBA emulator on a computer or mobile phone.
This post recommends 5 best Nintendo DS emulators to you. With them, you can play Nintendo DS games on PC.
Best GBA emulator for PC
In this part, I will recommend you top 3 best GBA emulators for Windows PC. Keep reading to get them.
1. Visual Boy Advance
The first best GBA emulator for PC I would recommend is Visual Boy Advance, which is one of the most stable GBA emulators and has been in existence for more than a decade now.
Visual Boy Advance is an open-source and free GBA, GBC, GB emulator software. It supports Windows XP, Windows 7, Windows 8, Windows 10, and also supports MacOS as well as Linux platforms.
However, although Visual Boy Advance is quite successful and very popular, the author has stopped updating for many years.
But because it is open-source, some developers later developed a modified version of VBA-Link that supports online mode, and a derivative version of VBA smooth that has various layer or filter display effects (such as anti-aliasing).
Later, some developers combined the functions of the two versions and released the latest VisualBoyAdvance-M emulator (VBA-M). Many people think that the VBA-M is the most powerful and easy-to-use GBA emulator.
VBA-M is only compatible with Windows and Linux, but not MacOS. Finally, when you install Visual Boy Advance, if it prompts that there is an error such as missing d3dx9_43.dll, please install DirectX 9 and run it again. Even under Windows 10, you still need to install DX9 separately.
This article will show you 6 Xbox 360 emulators that can be used on Windows PC. With Xbox 360 emulators, you can play Xbox games on your Windows PC directly.
2. No$GBA
Another best GBA emulator for PC is No$GBA, which can quickly cover most of the emulation. This simulator can also play Nintendo DS games in addition to being able just to run GBA matches. And there are no issues with the emulation. The games are smooth and the sound is clear.
This emulator has the following advantages:
- Capable of running both Nintendo DS and GBA games.
- Allows playing multiplayer games.
- It is stable perfectly optimized for gameplay.
- Supports game controllers.
Its disadvantages are as follows:
- No support for Mac or Linux.
- Not all Nintendo DS games may be supported by the emulator.

3. RetroArch
The last GBA emulator I'll recommend is RetroArch, which is a multi-system emulator using Liberto development interface. This system uses 'cores'. Each 'core' is essentially a video game emulator and you can install it accordingly. Game Boy, Game Boy Color, Game Boy Advance, PS1, FC, etc. all have 'cores' that work in RetroArch, making it possible to play all of them with just one app.
It's open-source and has a high compatibility rate. It is compatible with Windows, Linux, MacOS, Android, iOS, Raspberry Pi, and Apple TV. In addition, it can run on PS3, PSP, PS Vita, Wii, Wii U, Switch and other game consoles. Actually, this thing runs on virtually everything.

However, RetroArch doesn't have quite as many features as individually coded Game Boy emulators and it may be more complicated than other emulators. You'll need to learn how to use it. In addition, it can crash at times. If you are experiencing frequent crashes, try switching to an older version of RetroArch.
