Nanoloop two can send and receive sync signals via the cart's built-in mini jack port with a standard 3.5mm audio cable. Since the Game Boy's link port is not involved, sync is also possible on devices without link port such as Game Boy Micro and DS / DS lite.
The cart is covered with standard 8mm grid plastic tiles in random colors that can easily be replaced with compatible parts such as LEGO®, BlueBrixx etc.
Nanoloop two saves data in flash memory, there is no cart battery.
Nanoloop two works on all GBA-compatible Game Boy models (GBA, GBA SP, GB micro, DS, DS lite) and Analogue Pocket.
It does not work on other GBA clones such as Revo K101.
