Finally someone to give an much needed update on these server tools.
I know must of people are stuck with no budget or a small one but all these CP tools are the same since forever.
I wanted to do something similar myself but unfortunately i don't have enough time free to dedicate to that and the amount of work is really big if you want to do like you and create something nice and from scratch.
One idea that i had you can may consider is to have the ability to interact with game data in real time. So you can use your system to talk to someone or deliver items and so one. ( I didn't check the emulator code to see how this could be achieved)
If one day you decide to open this for community contribution or something let us know.
