Does this play Game Boy Advance cartridges?
Currently, compatibility with Game Boy Advance® cartridges is a beta feature. Some titles may work, but not at 100% capacity and for the most part, not as they are intended to work. This will hopefully be updated once new versions of the firmware become available.


Aside from the pack-in controller, what other controllers are supported?
The RetroN Sq supports Hyperkin BT controllers: Cadet, Scout, and Admiral via the upcoming AlphaStar BT adapter accessory. Click here to purchase the AlphaStar!


Why is there a Memory Card slot in the back?
The memory card houses the firmware for the RetroN Sq. The console cannot operate unless the memory card is inserted.


Can the RetroN Sq play imported cartridges: Japan, PAL, Germany, etc.?
Originally there were no region restrictions for the original Game Boy®, Game Boy Color®, and Game Boy Advance® systems. The RetroN Sq is region free.
