I’m kinda out of touch… Does the emulator record the achievements or does it rely on honesty?.. Is there a guide to setting up?
The emulator, either through RALibretro or through Retroarch automatically watches for specific RAM changes where achievement developers at Retro Achievements design. We also have a very active discord community. Anyone can sign up to become a Jr. Dev and make sets!
Users just need to create an account with Retro Achievements and then users can sign in via Retroarch
Retroarch → Options → Achievements (be sure to turn on hardcore mode for leaderboards)
You can also download the standalone RALibRetro, sign in using your RetroAchievements account, and download the Arduboy core ( Settings → manage cores → Arduboy [Arduous] )
