@superretrogamer: I'm glad you enjoyed the article!

I really hope you'll have fun doing your own GB game, and please feel free to share it here!

Hi,

Your longboxes look very cool, congratulations! For now, I'm focused on cartridge-based game (my next title should be a SNES game ;)), but I keep the link to your CD case in case I try my hand at a Saturn or PlayStation homebrew (both of them would be very fun to do I think!)

A few months ago, I created and released a Game Boy game on cartridge, called Sheep It Up!

For those of you wondering how can we make a game for an old console with today tools, I've just finished writing up a long article detailing how I made it, from graphics to audio including building new cartridges.

You can read it here.

If you're into retro game development, please feel free to ask me any question about this project!

Hi, thanks a lot for your interest in the game!

I'm just the game developer, the assembly is actually made by my publisher Catskull Games. So I must confess I can't directly answer alll your questions for now, but I'll ask Catskulls about the specific details and post his answers here.

What I can answer for now is that the PCB are manufactured anew: he's not using old GB games PCB and simply replacing chips as other homebrew release did in the past. Catskull is doing the assembly by hand, but I'll ask him what tools he's using.

I'm also sure he's using chips rated to run at 5V, as Catskull is caring about using quality materials.

Meanwhile, here is a picture of the PCB (it's tiny, so it can fit both original GB carts shells and aftermarket cart shells):

EDIT: I've just got the answers from Catskull

"- Yes it's 5v.

- I get the boards made in china and hand assemble everything with a reflow oven."

I hope these answers are the ones you were expecting! :)

Hi everyone!

I’ve just released a new Gameboy game on cartridge: "Sheep It Up!"

(yes, there are people still making Gameboy games in 2017!)

Cart photo: http://www.ludoscience.com/files/static/Image/sheepitup_cartridge.jpg

It's an arcade game where a sheep has to climb up by hanging himself to flying velcro straps. The concept is simple, but the game rapidly gets quite challenging: how high can you climb without falling down?

As a game collector myself, I wanted this game to be produced without sacrificing any vintage Gameboy titles. So everything is manufactured specifically for this game: the pcb, the rom, the shell, the protective case and even the sticker! We also tried to keep the price reasonable, so everyone can enjoy the game: $15(+shipping). It will run on any Gameboy model: the original GB, the Pocket, the Color, the Gameboy Advance and SP, and the Super Game Boy.

If you still own a Gameboy, you can buy a cartridge from the publisher website:

I hope you’ll enjoy the game!
