Hi Folks,

I am cancelling this gameboy jam, as the original game jam by Retroshark is back & rather then split the communities I thought it better for their to be one gbjam.

I started unofficial gameboy jam last year because the official jam wasn't happening. I assumed that this would be the case again this year and fortunately I was wrong.

You can find the jam here:

Thanks for all your support and good luck with the jam!

Teams are allowed & encouraged! I recommened teams up to 3 or 4.

In terms of creating teams, feel free to create a board on the jam forum and see if people want to collaborate.

So Making an actual Gameboy game if you dont already know is going to way more difficult then just using something like Unity or game maker. There are less resources in terms of documentation and help and it is much more complicated then modern engines.

Ask yourself what it is you want to achieve in the jam - is it to make a cool game? if so, then do that in the easiest, most empowering way and make something really unique

If it is to learn how to make an actual game boy game then great! But you probably wont be able to do that AND make a good game in all likely hood and you would probably do better taking longer then a jam to learn actual hardware.

I hope this helps!

Hi Nitrofurano,

This is unconventional but totally allowed!
As you say, be sure to stick to the right resolution and 4 colour palette.

Also, I wouldn't worry too much about porting it across and instead focus on making a cool game  (you can port after the deadline!)

It should be between august 21st & 15th really.
You could do what I am doing and practice before hand (but not submit that project & start a new one!)

Hi Siridakis,

There isnt an official palette per say (even the colours between gameboys themselves were never 100 percent the same) but anything that looks gameboy like is fine.
Feel free to change it up too! The palette I use tends to have a little more blue in there to make it pop.

It would be cool if people using virtual consoles could keep the same screen ratio!
for 128x128 px would become 128 x 115px instead.



  • They must not be a higher resolution then 160x144 (but anything less is fine.)
  • They must still use a 4 colour palette.

oh ok! My pad is plugged in so i was confused why i couldn't use AWSD! thanks!

What are the controls to this? Cant seem to get to a new game.

Thanks for the lovely words! I am going to revisit this and implement the feedback you suggest at some point soon.

Just the viewport. If you want the to to fit the size of the screen then that would have to be 160x144. 

But if you had scrolling it can be any size you want

That is fine!

Sure can! 

You can use any 4 colours but try to include  a gameboy green set if you go with wild colours. The palette which is in the UOGBJAM logo is quite nice.

I would say you are not allowed to use post processing for scan lines but you are able to use them within the game itself at the games resolution.

It wouldn't be allowed as this would generate more then 4 colours but you could fade between different types of dither.

In my game I fade on objects in 4 steps and make sure they fit the colour specs.

A lot of folks use game maker. I'm using it unity myself with the retro pixel plugin in. 

Mouse controls are fine!

No, only the original Gameboy Resolution is permitted.

(1 edit)

Teams are absolutely allowed! No restrictions on sizes either.  Just be sure to disclose who worked on the jam and get people to post WIP shots.

You can use existing music as long as it is Gameboy themed and you provide credits and get permission from the artist.

Music from actual Gameboy games is not allowed, as this is a copyright issue.

Mind if we make this the Official Unofficial gameboy jam discord?

No theme outside of the gameboy limitations (but feel free to set yourself one!)

Depends on the frame work? Basically we want to avoid people reusing stuff from existing projects.

Is there something in particular you want t reuse? Give us details 

No problem. If you have any more questions or issues, ping me on twitter!

This is a super interesting question! Generally, I would advise to have the game run full screen but at the correct gameboy ratio and possibly have plain borders BUT I will allow Super gameboy style border graphics as long as it is clear that it isnt part of the game.

Below are examples of this:

However, I would also add that these background must also be four colours (but they can be a different four colours to your game)

GBJAM is the only jam I always try to participate in so thats why i started the unofficial one, just as a stop gap!
