Iván Delgado, the developer best known for colorizing classic Game Boy games, has pulled back the curtain on a project he’s been cooking for years: GB Bridge, a modified Game Boy-to-GBA emulator that effectively “ports” original Game Boy titles to the Game Boy Advance.
Delgado, who goes by @toruzz online and has previously released colorized hacks of Game Boy titles, notes he actually dropped hints about the project as far back as six years ago. The secret was kept a little too well, apparently, and he’s finally ready to talk.
The core concept is clever. Rather than building a straight GB-on-GBA emulator (those already exist), Delgado designed GB Bridge to target what he calls a “fantasy console” that sits somewhere between the two systems. His description: “GB Bridge is basically a GBC with a different memory map, a bigger screen, and extra inputs.” The real trick, he says, is the use of special registers that trigger native GBA routines from within the emulator, allowing him to push the hardware further than a standard emulation approach would allow.
The result, at least in theory, is Game Boy games running on the GBA with expanded resolution, additional colors, and use of the wider screen real estate the Advance offers. Delgado has shared GIF mockups showing what that could look like in practice, with Super Mario Land cited as his current working test case.
That word “mockups” is doing some heavy lifting, though. Delgado is upfront that what he’s posted represents the end goal, not the current state of the project. “I’ve tested key parts and they are feasible,” he says, but follows that up with a direct request for patience: “Like most of my stuff this is long-term, so please don’t expect releases anytime soon.”
He also stepped in to address community confusion about what the emulator actually does, suggesting the mechanics are more nuanced than a simple plug-and-play solution. Each game will likely require substantial individual work to take full advantage of the system.
It’s early days, and there’s no release window in sight, but for fans of either handheld, GB Bridge is shaping up to be one of the more interesting preservation and enhancement projects in recent memory.
