Issue with ByteSearch based on VDP1 extracted tile

[feudjey]

First thing, hello all.
Second thing, I'm new here, this is my first post.
Third thing, I'm french, so please be kind with my English.

I decided to make an undub version of Saturn Bomberman, I find audio digits just much crazyer in japanese.
I was first looking for a way to edit audio in the US version but I didn't find any tutorial. In contrast I found Malenko's Let's replace Sega Saturn graphics great post in this place.
I do not have to follow every step because I have both JP and US versions of the game and only have to replace japanese text tiles by english ones.

First tile I get from VDP1 is the "Stage" button. Fortunately, all menu buttons have exacty the same address, width, height and color mode in both versions.

I won't have to edit the image, but I want to be sure I dumped the right data, so I open my stage_j.bin in Crystal Tile, and I get this :

I assume I can now look for the file containing my tile data in the japanese extracted iso.
I use ByteSearch, looking for a very small chunk, but always get 0 results when I search for more than 3 or 4 bytes:

PS D:\bomberman\tools> .\byte_search.exe --source_type string --target ..\dump\jp\  --source F77762222222AAA2

ByteSearch v1.7

I have no idea of what is going wrong. Maybe some files are compressed ?
I know .CPK are video files and .AIF are audio files, but I don't know anything about ._PRE and ._TRK
I hope someone can help me to go further.
Here is the files structure for the japanese version, everything is on the same level, no sub-directories.
Thanks in advance.

Byte_search won't be able to find compressed data by searching the uncompressed data. You could use a diff program like WinMerge ( WinMerge - You will see the difference… ) to compare the files from each version , that should narrow down where the data could be.
