There is overhead due to C being a stack-oriented language, whereas the Game Boy's CPU is rather built for a register-oriented strategy.

See the tips below to avoid such blunders. Using INT32s is quite taxing on the CPU (it needs to do two consecutive 16-bit adds, and add the carry). The Game Boy's CPU is only capable of performing 8-bit addition or subtraction, or 16-bit addition.

It’s easier to write inefficient code in C without realizing it.

On a platform with a slow CPU such as the Game Boy this can be a factor. It has matured a lot in the 20 years since the original GBDK, but bugs still turns up on occasion.

The SDCC C compiler won't always generate code that runs as fast as skilled, hand-optimized assembly.ASM can be included in projects with C, either standalone or inline for speed critical features.C source debugging is available through Emulicious with the VSCode debug adapter, making it easier to understand problems if they arise.The language abstractions make it relatively easy to implement ideas and algorithms.Allows for getting up and running faster than with ASM, especially when building on top of GBDK-2020 and ZGB.Code may not be easily shared with ports of a game on other platforms.Ĭ will typically be used with the SDCC compiler and GBDK-2020 or ZGB, though it can also be used on its own without a framework or with a different compiler/dev kit (such as z88dk open in new window).

Will require more time and learning to get up and running when compared with C.It's quite verbose and sometimes tedious.It takes a special kind of work to write optimized ASM code.When well written it allows for maximum speed and efficiency on the limited resources of the Game Boy hardware.

Most games and programs for the Game Boy written in ASM will use RGBDS or WLA-DX. It determines how much work is involved, what will be possible, and how fast it will be able to run. The choice of programming language is important and can have a very large effect on a project. The Game Boy Color can unlock additional functionality, such as more fleshed-out color, a double-speed CPU, twice the video RAM and four times the RAM! (With caveats, obviously.) # Languages The Super Game Boy adds a few minor things, such as a customizable screen border, and some crude color. Suddenly not so much, eh? It also has 8 kB of RAM, and 8 kB of video RAM a 160x144 px LCD (thus slightly wider than it's tall), 4 colors, and 4-channel audio. Its LCD boasts 60 fps, which rounds up to between 50,000 and 80,000 instructions per frame. Given that an instruction takes approximately 2 to 3 cycles, this gives the CPU a capacity of 333,000~500,000 instructions per second. The original Game Boy, codenamed the DMG, has a 1 MHz CPU. I will also provide some "good practice" tips, both for C and ASM, if you have already made up your mind or are already using one of these. The purpose of this document is to provide some insights and help you make the better choice if you're starting a new project.

GB Studio (a drag-and-drop game creator with scripting).

ZGB (an engine built on GBDK-2020) and the C language.

GBDK-2020 (Game Boy Development Kit) and the C language.

RGBDS (Rednex Game Boy Development System) and the Game Boy's Assembly language (ASM).

When someone wants to make their own game, one of the first problems they will encounter is picking the tools they will use. Please note that the Game Boy Advance also functions as a Game Boy Color, so if you only have a GBA, you can use it for both GB and GBC development.

If you want to program for the GBA, which is much more C-friendly (and C++ and Rust, for that matter) than the GB and GBC, then I advise you to download devkitARM and follow the Tonc open in new window tutorial.

Game Boy Advance programming has little in common with Game Boy programming. If you don't have the basics of C++ down, my first course teaches everything you need to know for this course.This document only applies to the Game Boy and Game Boy Color. This is a C++ course and some basic knowledge of the C++ (or a similar language) is needed.
