MatrixODE has recently updated their PS3 Optical Drive Emulator, and now the Matrix ODE is similar in operation as the Cobra ODE with its own new ISO Manager Browser system found in the v1.3 update package.
MatrixODE is one of last ODE's to enter the marketplace, and is basically a clone of the E3 ODE device, but with some improved parts so it is more stable in operation in the PS3 consoles it supports which are from older 2k5 Slim's up to latest 4k Super-Slims.
Like the other ODE's for later Slim models it needs a bit of soldering, and the only feature it offers compare to the others is an lower price, but with that lower price means you have to wait until the others update, and they figure out how to clone that update to make it with their product.
And finally the MatrixODE team has done just that with their v1.3 release which offers the New & Improved Browser that the hard-efforts of Cobra team had developed first, which allows you to quickly select and play your ISO's on your ODE HDD without the need of any homebrew manager, and without the need of ejecting or restarting your PS3 console.
