View in full screen to see it better, Youtube sucks.
Visit www .nicovideo.jp for the videos.
Also, if you're too lazy I have made an account for the forums to use:

When searching you have to translate to Japanese, another good way for correct translations is to search the game on Wikipedia.
For example Final Fantasy Tactics is:
ファイナルファンタジータクティクス
You can search for "FFT" it does bring up alot of results.
Funny video of FFT Chars someone made.
There's Mega Man!! Yugio and some others I don't know oh and Mario.
Mario's portrait is pretty good and hilarious at the same time.

*EDIT*
Just had a thought if we message these people on Nicovideo we could get a hold of some of these hackers! Here's the Nice Boat Hacker

Looks as though this person can event edit also, the dialog boxes are most likely fake I assume though. Also, looks like he has a whole big story with them at the top of the video you can click the sequel and it brings to the next story event. In Part 5-2 it looks like he edited an effect at around 2:15, unless thats already in the game...

Here's an extremely overpowered woman Delita type sprite, (Makes Orlandu look like cannon fodder)

Hmm, that first one seemed to be done in another program, the sprites were nice though. The second was odd... as you said, yes, some parts were obviously fake. The weird portraits seemed to deal something with FFTA, though Miluda in a witch's outfit seemed to fit her better then I thought it would. Also that Alma portrait was adorable. The Delita type, woman... thing... that was simply odd. Not much very impressive about it.
I think it was Tactics Ogre not FFTA, I just need to figure out how to message these people.
