Hyperkins popular RetroN Sq HD System has a new firmware update. The RetroN Sq allows you to play Nintendo Game Boy and Game Boy Color games in crisp 720p on your HDTV. And while it was also somewhat compatible with Nintendo Game Boy Advance, there were frame-rate issues among others.

Now Hyperkin has released the next firmware update to help address some of these issues! Here at Gametrog we thinks it’s great that Hyperkin is following through with it’s promise to continue to update this system. Here’s what you need to know:

RESOURCES

Firmware Update SD Image Version 1.2

• Improved framerate for Game Boy Advance®
• Aspect Ratio is now console accurate for Game Boy Advance®


Note: All in-game saves are stored on the RetroN Sq. Saving in-game will not affect the save data on your game cartridge. ** Updating the firmware on the Micro SD card will delete all game saves and game progress stored on the RetroN Sq (save data on the cartridge will not be affected)**. This may change in the future.

We recommend using a 512mb memory card (Micro SD) with the RetroN Sq.

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. (Gametrog will have soon)
 

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.
