GioGio's Bizarre Adventure font file

[tempoman15]

I need help figuring out this texture file, the filename is nec20rg04.pzz
Offsets 10000 to 20000 seem to contain the english letters
I can't figure out what type of texture it is
On the attachment you can find the file and a couple of images

Ok so I just found out there was a chinese fan translation of this game, and they edited this file to add chinese letters
This means that now we have two samples, and that it's possible to edit it
Here is a comparision between the two

UPDATE: I managed to get something close to a preview inside TextureFinder, but it still doesn't look quite right.

do you have more pzz samples to compare against? while extensions are usually meaningless,
the double zees in there could indicate some type of compression being used.
this is a PS2 game right? most ps2 image formats are paletted but i don't see anything right away.
i'm not good with fonts but most i've seen were 8 bit alpha images, i don't know if that applies here though.
i do see a 5 byte pattern through out the file but that is all.

@tempoman15
I tried 4BPP and 8BPP without seeing any results. But when I saw your latest reply, I adjusted it and changed it to 2BPP 4color mode. I saw something successfully. In fact you are very close to success.
@Acewell
Many Japanese games use tiles to make fonts.

Please try to decode this file with 2bpp 4 color. Tile: 20x20.
tile data range:start 0x800- end 0xbf200

Tile tools:
Crystal Tile 2

@Acewell
No other pzz files use this format

@Allen
I tried the program with your settings, and it worked!
I found the english font, and tried to edit it using the program



All text effects are handled by the game, so any simple edit works
Thank you guys so much!
