	Games - HES Unidaptor

The HES Unidaptor is the only device in the world that allows any Nintendo Entertainment System (NES) console game be operated on any NES hardware despite the 10NES region security chip. It was developed by Australian company Home Entertainment Suppliers Pty. Ltd. (HES). Two models were released the HES Unidaptor and the HES Unidaptor MKII. Neither version is compatible with the original Japanese Famicom.

Background

Nintendo in an attempt to prevent companies releasing an unlicensed Nintendo game (which isn’t illegal) Nintendo in later revisions of their hardware locked out these titles. To circumvent this, HES developed a technology to bypass it called the 'Piggy Back' or 'Dongle' game, where you could insert an official licensed NES cartridge into the back of a HES game and it operated the country code of the official title instead of HES'. This was so successful HES also used this technology to build a converter to bypass the 10NES security protocol entirely, released as the HES Unidaptor.

Other companies have release similar products but none that allows total conversion of all NES games on all NES hardware.

Models

HES Unidaptor

The original HES Unidaptor is quite a bulky device that has a cartridge that slips into the NES unit, and straps over the top of the NES. The component that lies atop of the NES has three slots. Slot 1, is the master slot which is where the user inserts an official licensed NES game compatible with the NES hardware so the 10NES chip can read the country code from the masters EPROM. The other Slot 2 and Slot 3 (called the slaves) allowed the user to insert either a 72-pin NTSC/PAL cartridge to play or a 60-pin Famicom respectively.

After the NES was switched on, the NES would read the security code from the local licensed title, and then execute the code on the slave’s cartridge.

This unit was only compatible on American, European, Australian and New Zealand NES', despite it played 60-pin Japanese Famicom games.

HES Unidaptor MKII

A more refined and cheaper version was released that was more similar in appearance to HES games. It was simply a card that slotted into the NES, which had two 'Piggy back' slots. The bottom being the master and the top being the slave.

This unit only supported 72-pin NTSC/PAL cartridges.
