The Duo 3 Ultra is here, the successor of the famous Duo 2 SE & Duo 3 mod chips. The Duo3 Ultra now supports v1 to v16 PS2 & PsTwo consoles, with the addition of Autoboot on all models. The Duo3 Ultra also supports the latest batch of PSTwo slimline SCPH-7700x. The Duo3 with its 17 wires for v1 - v8 and 22 wires for v9 - v16 is a popular and cheap Playstation 2 mod chip. The Duo3 Ultra like the GT runs on 3v instead of 5v, this is a good thing when working on v9 to v16 consoles. The other interesting thing we noticed was they have gone back to the old IC & PCB design. We think this could only be a good thing, as the Duo 2 GT did not have the same stability and reliability of the Duo 2 SE. We think this was caused by the new IC used for the Duo 2 GT.
