Welcome Tiaan64
Glad to have you here with us.
You will find a lot of resources on the forum, scripts, answers, help... don't hesitate to ask if you have issues.
Feel free to share your projects, WIP, comments, ...
I also strongly suggest to watch all the tutorial videos before starting, those are very important (I insist). You can't use NESmaker if you don't know how it works, how to set it, some important concepts, ... and folloing the tutorials, you'll be able to make your first NES games.
Have fun!
