TiledGGD, color?

[altheonix]

Hi , I'm a beginner in sprite ripping.
I've been trying to figure out how to use TiledGGD for a few days.
Today, I got my first rip. Yaaay...

Next, I want to try ripping Touhou hisoutensoku sprites. There is th123a.dat file in the game folder.
I am sure th123a.dat file contains the sprites, I tried to open the file in TiledGGD but the graphic and palette didn't appear. Maybe, it happened because the file size was to big.(~900MB)

So, I used hex editor to split the file.
yeah, I found something but the colors wasn't right.
I've changed the color mode, endiannes mode and moved the graphics 1 byte but I can't find the right color.

this is the closest color i can get.... (yuyuko)



this is the right color


How to get the right color?

I know another method by using memory dump from the game.
I just want to know what's wrong in this method . I think it's a lot easier to rip from the dat file rather than memory dump.
