Turning a DS into a Game Boy Advance

The venerable Game Boy is dead – and has been for a long time – after being replaced by the DS, DSi, DSi XL, and the 3DS. That doesn’t mean there’s nothing of value to the old Game Boy catalog; Pokemon Red/Blue is still as much fun as it was 15 years ago, and the game play of Advance Wars is still superb.
[Maarten] over at Bureau voor Gamers decided to put a modern twist on our old friend by taking a first-gen DS and converting it to a proper single screen Game Boy (Dutch,Google translation).
The donor machine was a broken first gen DS with a broken top screen. [Maarten] removed the top screen, did a tiny bit of Bondoing, moved the speaker, and gave his new toy a bright orange paint job.
Now [Maarten] has a modern version of the best portable system ever created, packed full of more powerful hardware and a much more capacious battery. Sure, it’s not a build that requires rewiring everything, but it’s still an awesome build for GBA aficionados.

Nice mod, perhaps make and sell them on ebay or such. They may well sell, especially when collectors are involved.
