You can play with both ps2 games if you have installed rebug there is a special firmware for the consoles. You can switch between dex and decr xmb in the Rebug Toolbox. With the dex xmb you can play ps2 games.I mostly use my decr-1400a for debug builds because it has more ram than a retail ps3 or test ps3.
