Crisis 2 is currently only available on seventh generation consoles, (sadly) too much of an ask for an rpi / rpi 2. House of the dead 2 is on sixth generation consoles, which is a lot less of an ask for the pi, but is still slightly out of the question.
However, there is quite a lot of talk of a Dream-Cast emulator around several forums and Ps2 Emulation, because the pi can technically emulate both of those hardware formats (you need roughly 10X processing power to emulate a system, without the architecture being very different. this mean any Microsoft console (they all have x86 architecture) can defiantly not run on a pi (arm v11/ cortex a7))
Maybe, as time goes on and with the right amount of work / optimization for the pi, it looks possible.
