I remember seeing this months ago and YouTube just happened to be cool and put it in my suggested videos   Anyone know where a download of the hack might be?  It looks pretty nifty.

I would but the user doesn't seem very English-friendly.  It seemed like 90% of the comments left would be responded with a "thank-you" even when someone was asking a question, unless they were asking him in Japanese... 

you can always open it in an internet browser and just set the encoding to Japanese

I'm not an expert on FF4 differences, so the only real thing I noticed in the FF4kai was that the floating eyes were redrawn in a different style.  Then I got that rare Cockatrice summon item which I've never gotten before--that was sorta nifty   I played up until right before you get Tellah, and nothing too different popped up to me. 

Thanks for finding this!  My brother started playing the FFVr and it's really cool so far, and I believe there's new items in the game too, so it's not only just enemies redone.  There should be some new music too.

EDIT:  I've trying the one you said the dungeon and stuff are also changed, and there doesn't seem to be anything different.  Later I'll download end-game saves and see if there's anything drastically different in either of the two hacks above.  And one of the files seems to be full of information on data offsets for FFV too

I haven't tried, but since there's different text in the game from the original--at the very least for enemies--there would probably be some things messed up eventually.  In the least-bad scenario, there'd be gibberish in some places.

But I'll probably try it tomorrow and see what all it does.  In the first town they have a new sword listed which sells for 3000G--I think the first is a Broad Sword, but I'm just guessing from the few (like one or two) Kana I recognize in the word
