Gameboy Development Forum

the game never halts, so it uses full cpu, and wastes battery (etc). on inspection it seems it might be running at undelayed framerate without ever waiting. you should, after every processed frame, use a halt opcode to wait for the next vblank, then you read the joypad and process the next frame. this caps the game to 60 fps and does not waste battery.

also you hit a "16 bits inc/dec in OAM range" exception. this can give problems on real hardware, and you should fix it. (enable the exception in bgb)

The game is really well done!
And I also liked the music. How did you implemented it in the game, did you use a specific software?

first, i would disagree that just because you're self taught, you can't make great things. as an example, i am self taught, and i made bgb. secondly, the use of halt opcodes isn't really special or difficult. if you made the game like you did it, it's a trivial detail, you just have to know about it.

the halt opcode suspends execution of code until the next interrupt happens, then execution continues at the interrupt vector or if interrupts are disabled, on the next opcode).

Fun game. Good work. Post up your source code for the community.

Wow, what a great title screen. The whole game is very well polished.  I love it! As you said, it really does look like a professional game that you would buy at the store. Now you gotta make some cartridges and sell them That is probably difficult though

And also, @beware thanks for making such an amazing emulator! I am working on sega mega drive development right now and there is no emulator as powerful and fully featured as BGB, which makes life tough :[ BGB was so helpful in debugging.

Thanks. It's great to hear that some people play and like it.

Rychan, there are plans for a small number of cartridges. But I won't produce them myself, so I can't guarantee for anything.

For me personally, putting the game on a cartridge is not that important. I love gaming, but don't care too much about little plastic boxes.

Congratulations for the game Jonas! Pretty solid and entertaining game. It is noticeable that you have taken great care of the quality.

Fair does. I've been searching for somewhere to produce them for ages myself

Seeing the circumstances and the interest, we could well create some thread to investigate this subject together. Documenting different options.

Personally I will try to share the findings I make about the physical distribution of software for Game Boy when the moment comes.

Thank you Jonas for the different links, it will be useful later on!

Awesome game! I love Breakout clones, I played a lot of DX-Ball on PC 20 years ago or so.

The website says there's a cheat code in the game. How secret is it?

Finally, Retroid has been put on cartridges. There was only a very limited run that is already sold out but there's still a chance that there will be another edition. Just wanted to show you guys some pictures (taken from a German review you can read here: http://www.pixelkitsch.de/retroid-pixel … #more-6066).
