Welcome to the ZGBJAM page!

Next weekend we will get together to make new awesome Game Boy® games using ZGB

What is ZGB?
It's a free open source little engine (plus a set of utilities) which allows you to create games for the Nintendo Game Boy®  and Game Boy Color® in C language.  It uses GBDK with an updated version of SDCC (3.6.0) Since its creation in 2016 several games have been developed even by people without a programming profile!



Why ZGB?
ZGB is easy to use and it lets you create games fast, which makes it a good candidate for a game jam. In order to get this done in 48 hours you need an engine that already takes care of the low level stuff (scroll management, collisions, bank switching, animations, texts, etc...)

Do you want to join us? Please read this page carefully :)


  • This will be a 48hrs jam, so we'll start at 27/07 18:00 (GMT+1) and finish at 29/07 19:00 (GMT+1)... the extra hour is for last minute uploading problems ;)
  • Theme is BOUNCE
  • Your game must be made using the ZGB engine.
  • You can make your game solo or with other people. There's no group size limit.
  • No offensive content will be accepted, including xenophobia, sexism, racism, etc. Please be respectful.
  • Don't stress and have fun!
