Gameboy Development on Mac OS X
Doom, Quake, Zork, and hundreds of other games took the primitive features of the operating system and created games that are fun and playable even by today’s standards. While macOS is not well-known for gaming, you can still play DOS games on your Mac. Learn how to play DOS games on macOS with DOSBox, the leading DOS emulator on any platform. What Is a Game Jam? A game jam is an event where participants try to make a video game as quickly as possible. Most game jams take place over a single weekend, where everyone has 48 hours to try to make a game often based on a secret theme that is either voted upon or chosen by the organisers. The theme is used as a limitation that encourages creative thinking. Coffee Talk is a game about listening to people's problems and help them by serving a warm drink out of the ingredients you have. It is a game that tries to depict our lives as humanly as possible, while having a cast that is more than just humans.

357294As I have gone more and more low-level over the past month, I was searching for a platform that is well understood/documented, not too fancy and thus allows me to use it for learning on different topics at once in a fun way. I.e. micro-processors/electrical-engineering, emulators, dev-tools.
Well, I found the old Gameboy to match that category:
- Electrical Engineering: Building own game cartridges/ROMs, ROM-readers/writers and play around with other interfacing possibilities. As it happens, I still have my old Gameboy lying around… somewhere…
- Emulators: Write a simple emulator for the Gameboy’s Z80 processor. Compared to others, the instruction of the Z80 is “quiet” small. Except for the CHIP-8 language, there are not many other processor that are this popular and have an as small instruction set.
- Dev-Tools: Understanding how compiler and linker for this platform work and tinkering with it. As one of the most popular tool-chains (Rednex Gameboy Development System358295) is open-source and a comparably small project, this is hopefully not a month-long endeavor.
And I like doing game-development for fun anyway. With a quiet old and restricted platform like the Gameboy, this is a nice thing to do in with limited time and good results. Building only a simple game for PC or any of the latest Mobile-platforms (iOS, Android) can take month when you also have some sense for art and style. With a four-color 160×144 pixel display, you are so restricted on itself, that doing the graphics yourself is quiet easy; even for someone that is not a great artist. I was surprised what can be achieved on a 14 hour flight. Maybe I will even enter the next Ludum Dare359296 with a Gameboy game.
The first step required to dive into the world of Gameboy development is to set up the development tools, emulator and some more useful tools like tile-editors on your Mac. The main purpose of this post is to describe the steps I have taken. And as it was more then just click-click-finish at some stages, I hope this will also be helpful to others.
RGBDS360297 seems to be a popular set of developer tools for the original Gameboy. It contains four command-line tool for which two are the assembler and the linker. Unfortunately, there is no binary available for Mac OS. Fortunately, it is open source. With minor modifications I was able to compile the tools for Mac OS X Lion. You can find the compiled binaries (rgbds.tar361298) and the Makefile I used in my github repository362299.
Next thing I needed for development was an emulator with an embeded deugger. Who writes a working game with closed eyes, loads it onto a gameboy cartidge and it works? Well, at least not me.
The emulators I found to be the best matches are no$gmb363300 and bgb364301. Both are similar feature wise; bgb seems to have been implemented based on no$gmb, so both interfaces look alike and also shortcuts in the debugger are mostly the same. bgb is still actively developed and you can also get tips by the developer in the EFNet #gbdev IRC channel.
Both emulators are for windows originally and they are not open source. So, using Wine was the only real option. If you don’t have Wine yet installed, you might want to download MacPorts365302. It is a package manager for Mac OS and also allows to easily install said software. As you also need to have the X11 window server installed for Wine to work properly, best is to follow these instructions366303 for the whole installation.
The Installation of wine itself is straightforward: After the installing MacPorts type “sudo port” in the Terminal.app to start the MacPorts package manager. Supply your user’s password and the prompt of the package manager should appear. Type “install wine” and do something else for the next half hour. This will download all dependencies (a lot) and install Wine on your system. I got an error like
while installing Wine because it seemed to interfere with other packages I have already had installed. If you also encounter this problem, follow the workaround at the bottom of this bug-ticket367304:
Once you have installed wine successfully, you can start the emulator. I was not able to get bgb running yet but no$gmb works just fine. Get the 32-bit Windows version from here368305 and start it with “wine NO$GMB.EXE” from the commandline.
As said before, a quiet restricted platform like the Gameboy allows also a developer without a hand for art to create nice games. Still, you might want some tools to assist in the process. The Gameboy Tile Designer369306 and the Gameboy Map Builder370307 are two such tools. Easily generate tiles and maps and directly export them into an assembler-file containing the required data to directly work with the tiles/maps. These tools are again windows-only but work just fine with wine.
Unfortunately, as of this writing, the host for these tools seems to be shutting down its operation completely, so I hope the owner of these tools will find another host soon.
That’s about what you need if you want to get into Gameboy development and have some retro-fun. To point you in the right direction for getting started I can recommend the notes of the Wichita State University’s 2008 Z80 Assembler Programming lecture371308. Luckily, the exact same tools we just installed on our system are used 🙂
A game jam is a contest where participants try to make a video game from scratch. Depending on the format, participants might work independently, or in teams. The contest duration usually ranges from 24 to 72 hours. Participants are generally programmers, game designers, artists, writers, and others in game development-related fields.
Traditionally, game jams focus on video games;[1] however, board games have also been the subject of game jams.[2]
History[edit]
The term game jam is a composition of the words game and jam session. A jam session describes the musical act of producing music with little to no prior preparation in an effort to develop new material or simply to practice. In the same way, game jams are events in which game developers prototype experimental ideas into playable games.[3]
In March 2002, video game developersChris Hecker and Sean Barrett, interested in the capability of modern hardware in rendering a large number of sprites, worked with Doug Church, Jonathan Blow, and Casey Muratori in developing a specialized game engine capable of rendering a massive number of sprites. Hecker and Barrett invited a small group of video game developers to meet in Hecker's office in Oakland, California for the purpose of creating innovative video games using this newly built engine. Hecker and Barrett named this gathering the 0th Indie Game Jam, a game design and programming event 'designed to encourage experimentation and innovation in the game industry'.[4][5]
Format[edit]
Location[edit]
Some game jams are local events, taking place in universities, conference halls, or other private spaces.[6] The Global Game Jam takes place at the end of January of every year, with over 800 locations in 100+ countries around the world.[7] The Ludum Dare is an example of a virtual game jam, an event where participants largely remain at home, but present their efforts at the conclusion of the jam.[5]
Time constraint[edit]
Game jams typically have restrictive time limits, ranging from a few hours to several days. This time constraint is meant to simulate the pressure of a deadline and to encourage creativity among ideas produced by game jam teams.[2][3]
Theme[edit]
A game jam may be centered on a theme, which all games developed within the jam must adhere to. The theme is usually announced shortly before the event begins, in order to discourage participants from planning for the event beforehand and from using previously-developed material.[3] In addition, themes are meant to place restrictions on developers, which encourages creativity.[8]

Ludum Dare 24, a competitive game jam event, featured the theme of 'Evolution'. As stated by the Ludum Dare rules, all participants in the competition were recommended to create a game based on this theme. However, the rules also stated that participants were not required to use the theme, which allowed for games to be made outside of the theme.[9][10]
Technology[edit]
The type of technology can vary depending on the type of game being developed, and among the different disciplines involved.
In a video game jam, teams are generally made up of at least a programmer and an artist.[3] A programmer would work in a development environment such as Microsoft Visual Studio for development in a .NET Framework application or Eclipse for a Java-based application. An artist may use tools such as Adobe Photoshop, Blender 3D or Autodesk Maya. Other tools used by developers include videogame frameworks such as the Unreal Engine, CryEngine, Unity, Godot, and Microsoft XNA Framework. If in a team, developers might use communication services such as Discord, and source control services such as GitHub.
