I just spent the last several hours reading this entire thread, and I simply must congratulate you, Lugia, on extremely good work!
FF7 isn't one of my favorite FF games, but I will most likely play this once it is complete.
My favorite game of all time is Final Fantasy VIII, and it makes me sad that there are no demakes of it...
I need to go to bed soon, but tomorrow I will assess the possibility of launching an FF8 demake. By that I mean whether it would be best to use an engine of some sort or use code from another NES game (like FF1), or something else.
I am the world's worst artist, so if I did it I would surely need help creating graphics, but I can do the programming, given enough time.
