Ballsy cover too, Amano's one of my favorite currently active artists but it takes guts to think his artwork on a cover is going to sell a game in the US:

That said, our stores have gotten tons of these in and the first shipment of them sold out like, not even halfway through the day on which they came in. We got another twenty-something in my store yesterday and there were three left when I left this morning. This and Animal Crossing: Wild World are selling much better than a lot of retailers expected.
This particular port is great, redone the way the WSC/Origins/Dawn of Souls ports were. It's based on the Japanese version of the game with the difficulty tweaked so that it's harder in some ways, but a lot of the cheap bullshit difficulty has been removed in exchange for a more fair challenge. The font is totally redone so it's all very clear and easy on the eyes now and several of the character portraits have been redrawn (almost all of them for the better too, they're more directly based on Amano's art now). The music is ported almost flawlessly from the SNES which I found very impressive for a GBA cartridge (check out Contra: Alien Wars EX, ugh).
They also improved the translation even more, using the re-translated Origins version while also subtley altering some of the transitions and grammar so that everything flows more smoothly. A lot of the stuff that was silly when I first played the US version years ago holds up today. The entire game holds up very nicely.
Graphically it's the NES graphics with much better colors, nice stuff, all the battle backgrounds are totally redrawn and most of the monster sprites and animations are no longer restricted by the SNES color pallette.
Interestingly they also changed the money from "gold" to "gil" to associate it with the later FF games more I guess. The spell names also have their original names again. In the Japanese version they all had suffixes for each level of spell like in the Megami Tensei games but these had to be changed to Lit-1, Fire-3, etc. so that they could fit all the English characters within the font system for the SNES version.
Overall it's a very polished game. I'm having a lot of fun with it, very nostalgic.
