Glad you didn't give up on this huge project! I hope we can get some programmers working on this. It is sad to see in this day and age that Indie developers have little or no access to buy gamemakers or toolkits that provide the proper framework to help us design games like Zelda 3 for commercial purposes, let alone non-commercial games! It just blows my mind, cause its an epic system.
Besides this incredible project working inside RPG Maker XP, the only other real option is to work with systems like Unity, Gamemaker, etc. And even though they have many more features than XP, they still don't have a solid character and event database that I can see.. Hell, you even have to program the simple act of movement in Unity.. its such a setback in my opinion, or correct me if I'm wrong.
