If you want to do this as a business, pretty much your only bet would be to make contact with the original systems operator (or game publisher,) and see if they would be willing to let you license the needed code. Then you need enough developers who know the system in question and networking to actually develop the feature you need.
It sounds to me as if you're very unlikely to achieve what you want with the resources you have.
Well I did come here for an honest evolution w/ anyone who was very unfamiliar w/ our setup, so your answers works for me. Now as for contacting the original systems operator (or game publisher,) and seeing if they would be willing to let us license the needed code is out for our reach. Their are a lot of draw backs by presenting ourselves openly to that company, and one would identifying our intentions by putting us right on their radar (trying to avoid that as much as possible).
However it would be easier if their source code was free for public use, but that does not look like it will happen anytime soon. So re-engineering what we have so far from the original is what we have to work w/ as of now, and its a good start. Just wish we had our own network like the original console had, because video game R ran right through that network which is a draw back for us.
