This rendering process can be emulated by keeping track of the modes. Once it has drawn all 144 scanlines, it goes through the vertical blanking periodĪnd it resets itself at the top of the screen to start the process again. Period where it resets itself far left and one scanline down. Once a scanline is drawn, the beam goes through a horizontal blanking

The Gameboy’s screen resolution is 160x144 pixels.Ī lot of the old video displays update the screen in scan lines It is important to emulate and keep track of these hardware timings. When the Gameboy is running, there are certain times when the video hardware is accessing video memory.īecause games are not allowed to write to video memory when the GPU is reading from it, Once this counter goes above cycles_per_frame, then we know that it is time to draw a frame to the screen. Then the GPU struct needs a variable to count the number of cycles since the last frame. Let cycles_per_frame = clock_speed / FRAME_RATE Since we know how many times the CPU cycles per second,Īll that we have to do is divide the CPU cycles per second by the number of frames per second: const CLOCK_SPEED: i32 = 4194304 This means that the screen updates or draws a new frame to the LCD screen 60 times per second. Interestingly, the Gameboy has a very smooth screen refresh rate of 60Hz.

Keeping track of the cycles taken is important to keeping all other hardware in sync. The Gameboy’s other hardware (video/audio/etc.) is all tied in with the processor speed. This procedure reads the next instruction from memory and translates/carries out the task it represents.Įach branch returns the amount of cycles taken for that instruction. We can equate a block of memory in the hardware to simply allocating N bytes of memory in our program: pub fn new() -> Wram ", opcode, ) Regardless of what is actually being stored in each memory location, we represent it in the same way. Memory is one of the easiest things to implement in code. The Gameboy has a few different types of memory that need to all be emulated:

Interacts so we can form an understanding of how to emulate it in code. With this in mind, let’s take a look at the hardware of the Gameboy and how it all Virtually simulate how the real hardware of the gameboy would function. This means that in order to create an emulator for the Gameboy, we have to That run on it and tell it which instructions to execute.Īn emulator works by virtualy representing the physical hardware of the guest machine. When we view the Gameboy as a computer, the video game cartridges are the ‘programs’ We know that a computer is a device that can carry out logical tasks. The Gameboy, along with all old video game consoles, are nothing more than simple versions of computers. There are many systems that can be emulated,īut the choice was easy for me since the Gameboy was my first videogame console. Pseudocode will be presented in Rust syntax. The host system can be any version of Linux/Windows/MacOS. This page will describe what I learned during the process of developing an emulator for Is an incredibly rewarding and educational experience in many ways. However, taking the time to understand how an emulator works under the hood Write them off as some kind of black magic witchcraft. Many people who have used emulators (my younger self included) tend to To run on an entirely different system (the host).

An example is the DeSmuME.An emulator is a piece of software that enables programs for one system (the guest system) As for Nintendo DS emulators, there are lots of them available on the Internet.

The idea of emulating video games is not new, however with growing processing power, there are now emulators for Nintendo GameBoy and GameBoy Advance and Sony PlayStation and PlayStation 2, iPhone Emulator, Android Emulator.

Nintendo DS Emulators essentially emulates the DS on another platform like PC or Mac OSX. For reviews and firmware kernel downloads of R4 3DS cards please go to R4 Shop as it is the official online store for Nintendo game flash cartridges and backup copiers.īut if you would like to get the DS gaming experience without any cost, why not try a DS emulator like No$GBA or DeSmuME. To backup Nintendo Cartridges to PC and make your ownĬasual and hardcore gamers as it is should always consider playing DS rom games on the NDS console using a 3DS R4 / R4i Gold DSi Card.
