Kaico always try to assure that all products we stock are shipped with the latest firmware available.

Due to the nature of mass manufacturing, sometimes products are stocked in bulk before a new firmware is released. This happens very infrequently because retro gaming firmware does not get released that often.

However, when it does, it is often a very simple process to update firmware.

Please have a look at the following Wiki/GitHub links which provide information on the latest firmware downloads and general information on some of the products we stock:
