Show HN: Play Pokémon to unlock your Wayland session Hello everyone! I've created a gameboy emulator to unlock my Wayland session and wanted to share this project to everyone here! I've been a Linux enthusiast since I was a kid. What always captivated me was the freedom to customize my system exactly the way I wanted. With Wayland, we've reached an incredible level of performance. It's like turning your operating system into a video game! I've always been fascinated by the blend of fun and the serious, technical nature of an OS. That’s what inspired me to create this project. I started by studying Wayland, its protocol and how to build a compositor. Then I became particularly intrigued by the concept of a locker, which reminded me a bit of an escape game. That’s when I thought: how cool would it be to solve a puzzle to unlock your session, instead of just typing a password? Since I’ve worked with emulators in the past and I’m a huge Pokémon fan, the idea of building the puzzle around that game came to me instantly! Technically, the locker code and the wayland protocol have been implemented from scratch ( using EGL and wl_keyboard_listeners ). My locker runs a version of the gbcc emulator modded by myself. This emulator waits for one precise value to be set in a given memory address. I have modded the Pokémon game to my needs: when the password is good, I put the good value in the good memory address so the emulator knows it needs to unlock the session. Hope you will appreciate this project! https://ift.tt/bzFv8Lc August 10, 2025 at 05:45PM
