Amagami .ARC (PS2)

[Mysticus]

I need some help to extract .arc files from the game called Amagami from PS2. That probably contains images.
Is there some program?

.arc is an archive file.
Inside the file is a collection of TIM2 images.
8BPP is the standard TIM2 format, 4BPP is a font file, the font uses 24 * 28 tiles.

Thank you!
But the extracted images are bright.
Do you know an alternative way?

I found that I can view TIM2 images correctly with Noesis.
You can use the following script to unpack.

Code: Select all

#Game: Amagami .ARC (PS2)
#By Allen 20191202
#script for QuickBMS http://quickbms.com
#unpack tim2 images

get numFiles long
get indexChunkSize long
set skipsize long numFiles
math skipsize * 4
goto skipsize 0 SEEK_CUR

for i = 0 < numFiles
get type long
get hash long
get offset long
get size long
savepos next
goto offset
getdstring fourcc 4
if fourcc == "TIM2"
   set name i
   string name + ".tm2"
   log name offset size
endif
goto next
next i

I provide 2 methods,
1. Use quickbms script to unpack and use Noesis to view (but does not support tiles).
2. I just updated the conversion tool and it can be extracted correctly.

How to use the tool: Drag files to the program.

EDIT:
Update 4bpp tile format.
