I would like to make a money system in a game, but the variables do not pass 255,  is there a way to exceed this amount? because 255 is limited for a game with shops. Thank you


The best software ever!I am big fan of Game Boy Color games,and now I can make my own game?!I am so excited!This is so awesome!!!!!!

If I set My HP to value $01$ =10

and set if i interact Enemy

math functions = Subtract $01$ 15 Value

and set 

if value $01$ Less then or Equal to = 0 

it must change to Game Over scene

but it's not working 

But i Subtract $01$ 10 Value 

it's work!

(I must subtract 10 only? )

(I'm sorry for my english is not good but

i hope someone understands )

You’ve got an Underflow.

10 - 15 = 250.

When a byte goes below 0 it turns into 255.

You should check that the HP is greater or equal than the damage, if it is, substract 15 from hp, else, set it to 0.


I do tutorials on youtube


I've downloaded both the installer and non-installer version, but neither application does anything. I look in the folder it was said to install to and I can't see anything. I'm using windows 10. I hope I'm not just missing something or skipping a step. Any info to point me in the right direction would be helpful!


Your PC must be broken then, buy a new one.


You might be closer to the truth than you think haha.

Hi Admbrns, all I can suggest is checking first if you need the 32-bit downloads instead, if that doesn’t work I wonder if your anti virus software is not liking the app and maybe you need to whitelist it.

I hope this helps.

That is very likely it. I tried on a different computer and it worked wonderfully. Thank you for the reply

Nice project! Currently, I'm working on an open-source cartridge design, so this project is a great addition.

I'm running Ubuntu 18.04 on my machine, but gb-studio doesn't launch. I tried version 1.2 and installed via dpkg, everything seemed to be fine, every dependency met, but it won't launch. Same with the nightly build. I'm kind of stuck because there is no error message. I tried ldd and noticed, was missing so I installed it. No success.
Here you can see the strace:

Hi thor171,

That's really weird! I just installed a clean copy of Ubuntu 18.04.3 on a VM and downloaded the dpkg from here then opened the file (didn't even need to use the Terminal, don't know if that's new) then ran `gb-studio` and it opened as expected. Only things I installed were virtualbox-guest-utils and virtualbox-guest-dkms packages, potentially they could have included some dependencies that made it work :-/

Assuming you followed the instructions at the only other thing I could suggest if you're comfortable is installing from source. If you have git, nodejs and yarn installed you can clone the git repository and then install the dependencies by running `yarn` and start the application with `npm start` 


Thanks for you answer Chris,

I solved the problem, somehow. There was an environment variable in my .bashrc which was set "wrong". I commented it out and everything is running fine. strace gb-studio showed, that it couldn't find the needed libs, that's why I was thinking it should be something about an environment variable.
Guess I have to find another way to point to my programmer device's driver.

Anyway, thanks for your help. When my cartridge is working, we have to talk about its special functions support in GB-Studio ;-D


Does anyone know of literature that outlines the possibilities of Title Screen animations?

I know Chromebook versions might not be very easy to make, but I'd personally like one. Thanks if you do start working on that though! ( Not sure why you would but...) I think 32 bit is the best you can run on a Chromebook, but I'm not sure. Thank you in retrospect!..

Why not enable Linux support for this (on the Chromebook)? Get it but you could get it working on that I guess.

It kinda removes the whole purpose of a Chromebook, thanks though!

Yeah I know, but it is useful when you need that application you can't get in Chrome OS.

A Chrome OS I guess would be a web based version of GB Studio?

Okay! Thank you! Have a good day!

I must ask, does a 32-bit version of Linux work, and, if not, will there be a 32 bit version in the future? This is a great tool!

I will keep a Eye on this, looks very interesting. :) I love oldschool GameBoy Games.

That looks like a pretty cool tool! I make experimental games, and this is my kind of jam.

If it's easy enough to pickup, I might actually organize a workshop about it in my local game dev community :) 

I’d like to do something here with this via workshop, no clue where to start but the manual and youtube. Maybe I will search high and low for info on rpg creation and asset design. I think it’d be cool for an export function for standalone app in win.linux.macOS and mobile one day.

Long awaited update! Thank you! :D


THANK YOU! I love this tool. I am making my first video game ever because of it.

I made a donation for version 1.2.0.


I just want to say that you are a hero to me, Chris. This is my favorite piece of software ever released for free.


Awwww yeahhhh coloursssss.

What Sprite editing tool would you recommend for making games


Piskel is good too:


This is truly an amazing tool! I don't usually comment stuff, but I want to encourage you to keep on developing this awesome software. I also want people out there to make tutorials, publish their games, everything you can so GB Studio grows more and more!


I've always wanted to make retro games that work on retro systems, and i was on perfect timing!

I got so excited when this was featured and downloaded without issues!

Is recommended!


Oh, and gladly it supports MS Paint, plus having the same sprite as so!
