You have a point, as this thread is not very productive, and it's mostly negative, but seeing the quality of their work, it's not like the people behind these things wanted to do anything worthwhile neither...
if they didn't care, I think it's fair to ask, why would we?
I mean, i'm sorry if I sound like a grandpa here, but Squaresoft did better in the past, look no further than the Wonder Swan Color ports of early FF games or SaGa games. You could see effort in them. The GBA games, while some having issues (Like NTSC-U FF4) still were better than these ports, most of the time with extra content.
Damn, in FF4 Advance's case you could play with the other characters. Maybe a novelty, but a nice one.
...I guess we could say that Jorpho's question was somewhat answered. There is little to no attempt to hack/fix this things because there's really no interest for them.
At least not as much as with the original versions, or some of the (Better) ports.
