Updating Snake '97

About the challenges of developing a wildly popular game

Feb. 21, 2018
This month I bit the bullet big time: I redesigned the game engine of the wildly popular Snake '97 game. Read about the design challenges in this blog post.

Few years ago my brother threw a beer on my iPhone in an Amsterdam bar. The poor thing didn't like the Dutch brew as much as I do: it died. While waiting for a new phone to arrive, I used an old one that couldn't do anything but texting, calling and... Snake! The idea for Snake '97 was born and this month it was time to update the wildly popular game.

Repairing a Nintendo Gameboy Advance SP

Chip surgery to play classic Zelda

Mar. 26, 2017
Reparing an old Nintendo Gameboy Advance to play classic Zelda again.

This month Nintendo released the Switch with Zelda "Breath of the Wild". The new console received positive reviews. The new Zelda game is amazing and can be played on-the-go, thanks to the portability of the Nintendo Switch. But it its hardly the first Nintendo device that features the mythical kingdom of Hyrule with Link and princess Zelda. I found an old Gameboy Advance, perfect for playing classic Zelda games... but it was in need for repair!
