GBRetroDev 2025: Awards Ceremony
🎮 Join us live for the GBRetroDev 2025 Awards Ceremony! Get ready to witness history in the making at the GBRetroDev 2025 Awards! ( https://itch.io/jam/gbretrodev25 ) Hosted by the University of Alicante, this isn't just a contest—it's a celebration of pure coding grit. We challenged student teams to do the impossible: build an original Game Boy game from scratch, in raw Assembly, with zero prior experience. In just seven weeks, they've gone from "Hello World" to full-blown cartridge-ready games. ## Meet the Jury: From Students to Masters Our judging panel knows exactly what it takes because they’ve been there. We’ve assembled an all-star team of UA graduates who turned their own final degree projects into Game Boy reality: - Alberto Rius Poveda ( Crea tus juegos para Gameboy, 2024 ) - Víctor Conejero Vicente ( Whyrm, 2022 ) - Ángel Jesús Terol Martínez ( Golden Sacra, 2020 ) - Enrique Vidal Cayuela ( Project Rogue, 2020 ) - Ángel Navarro Martínez ( Galahad Escape!, 2019 ) - Jesús Hernández Fernández ( Packedtory, 2019 ) ## 🌟 Special Guest Expert: Marc Robledo We're also honored to feature Marc Robledo, a renowned ROM hacker and tool creator whose work—including the industry-standard Rom Patcher JS and his stunning 'DX' colorizations of classic titles—has revitalized the modern Game Boy scene, as our guest expert. Whether you're a dev, a retro collector, or just love indie creativity, you don't want to miss this. Come hang out with us, support the next generation of developers, and discover the future classics of the Game Boy library. See you in the chat! 🚀

A very good remake of the original 1982 BurgerTime that also acts as a perfect example for a colorization hack tutorial.

This is one of the small projects that I’m working on this year, with my brother @victordevelops.com and more friends. It has born in a game jam and we’ve been working on it every Saturday morning. Can’t wait to show it in movement!

Super Sunny World (my upcoming NES platformer) will have a number of hidden items required to reach 100% completion.
To make this more manageable, I've included a stats page with a breakdown per level of what you are missing!

STOP THE PRESSES.
The ROM for the unreleased Famicom RPG Splatter World has been released (in a thread on 4chan, of all places). I've tried it myself, and it does seem to be genuine. If it's a fake, it's a damn good one.
Expect (more) coverage on West Mansion soon.

I panicked today when we ran out of free ROM space in KOF: Battle de Paradise for new texts.
Glad I was able to fix it (the lack of good NGP debugging tools is still an issue, though).
Project status: 977/1193 texts have been translated :-)
