Believe it or not, this is percisely what the PC pac allows a person to do.. by making LD discs readable, searchable, and perhaps put txt on screen, with user selectable options. If software could be made that fits in a MegaDrive or PCE flashcard to do similar operations, it can easily be done! Not original games, but some creative stuff could be done witha lot of 'fairly easy' to get LDs. Now, I have heard that once 'cart' mode is enacted, it basicly locks down the LD drive. That will have to be circumvented somehow.
