I'm wondering how this is can be done when the NES IPX socket's aren't compatible with LCD point's and/or anything remotely toward a CD-ROM. The Nintendo Interface Network also has addressed that something like this would only fit well into a SNES due to the amount of RAM needed. A regular NES, In my theory and view's, isn't capable of being remotely like a computer, let alone a cd-player.

Sorry but I think the idea is creative and interesting but I can not see how it can happen. Good luck though!
