is there or can you make a gui for the .jar in the releases?

i can’t use terminal

Since the latest updates, Pokemon Blue/Red crashes when loading the game world:

Stacktrace:

It still worked fine with commit: 9f2ea20
But is now crashing, commit: 660ce4b

So something in between those commits likely introduced a bug.

Hey trekawek,
nice work with your gb-emulator. I would love to play some games with it.

Is ther a feature to save my games or open the .sav games again.

Thanks in advance,
Finn

Not sure why this is happening. The emulator runs (sometimes) at full fps, and sometimes at a severely reduced FPS. Sometimes I only get 1-2 frames per second, with obnoxious beeping sounds because the audio can't smoothly play.

I am running Super Mario Bros Deluxe rom with Oracle JDK 8

Hi there!

I currently host a ROM Hack on my website using an embedded flash emulator, but since Chrome is going to discontinue flash soon I am looking for a Java/other type of embedded emulator to replace it with.

I found your Java GB, and I was wondering if this would work for me. If so, could you help me set it up?

Thanks and let me know :D

Can I get permission to include and modify this emulator into one of my own projects (it is an minecraft mod)? (I will include credits in the mcmod.info file, curseforge page and github page)

hey, i am not into java that much but i need to build this, can you add how i could build this? Thanks

Discovered playing Pokemon Crystal. If you set the sound to stereo in the game options the left and right side are flipped. Easily noticeable during a Pokemon battle during attacks.

When I run the run.sh, I got the error following:
Error: Unable to access jarfile target/coffee-gb-1.0.0-SNAPSHOT.jar
Because it's coffee-gb-1.0.1-SNAPSHORT.jar in the target directory.

Please remove any concrete SLF4J bindings, such as slf4j-simple from your dependencies. This makes it hard for users of your project to define their own binding, such as log4j2 or similar:

This is mainly a problem because your artifacts are fat/uber-jars. So dependency-exclusions dont work. Ideally, a library would never include any concrete bindings but only the facade itself.

Cheers and thanks for this awesome project!

Hey, the usage printed out on the 1.0.0 jar has more info than the README:

Usage:
java -jar coffee-gb.jar [OPTIONS] ROM_FILE

Available options:
  -d  --force-dmg                Emulate classic GB (DMG) for universal ROMs
  -c  --force-cgb                Emulate color GB (CGB) for all ROMs
  -b  --use-bootstrap            Start with the GB bootstrap
  -db --disable-battery-saves    Disable battery saves
      --debug                    Enable debug console
      --headless                 Start in the headless mode

I don't know how that bar is called, anyway, you could add the program name there.

I came across this developing my own emulator, and gave this a try, but how exactly do you open this?

I've really been enjoying looking through coffee-gb's code recently. It's been a huge help in drawing inspiration for a Game Boy emulator that I'm currently working on, as the documents linked in the README are great, and your own code is very understandable.

What I'm wondering is, is coffee-gb's source code released under any particular license?

Whatever the answer, thanks for your work on this project!

Hi, I would like to know it the project could run in this kind of display:

178×128 pixel
Monochrome LCD

The display is part of Lego Mindstorms:
https://www.lego.com/es-ar/mindstorms/products/mindstorms-ev3-31313

The brick run debian and openjdk10

What do you think?

Cheers

The background of the pausemenu in Link's Awakening (not GBC) isn't getting rendered...

Basically, at the bottom keyboard row I have y x c and not z x c like you.

I would have to put my hands in a weird position if y isn't mapped to z too.

Hi,

I'm writing a port to make this emulator playable in minecraft. I'm noticing an issue where the FPS is not 'limited' resulting my game into running at superspeed. Is there any frame limiter built in? I might be looking over it.

It runs slowly but sometimes it speeds up and audio is stuttery, causing popping noises. Also, I think there should be a input GUI to assign controls to the keyboard, though the default key layout isn't too bad.
EDIT: The games run better now but it still has problems, GB games run better than GBC games as there is some stuttering in framerate.
