Arduboy Playdate Ports
From Playdate Community Wiki
|Arduboy Playdate Ports|
While this is not an actual emulator, I thought It would be worth to mention here that lots of games from the Arduboy are now actually running on the Playdate thanks to Eric Lewis's ported libraries.
A collection of ported games + a drop in replacement library for Arduboy2 / Arduboy2Playtune / Arduboy2Tones.
Checkout the github to find the source code for a number of game.
