Reverse engineering game data & extracting Japanese text from binaries

I build Python scripts to parse, validate, and reinsert text while respecting strict byte limits, offsets, and control codes.

Focused on low-level file structures, encodings (Shift-JIS / UTF-16), and stable data reintegration.

(Python is required to use my tools)


Strict byte limits matter: exceeding (xx bytes) breaks offsets, pointers, and can crash the game. (Applies to ALL scripts)
[Memory Structure Example]

OFFSET: 0x0010
SIZE: (20 bytes)

[Original Data]
48 65 6C 6C 6F 20 4A 50 00 00 XX XX XX XX XX XX XX XX XX XX
"Hello JP"

✔ OK → fits within 20 bytes

[Modified Data]
48 65 6C 6C 6F 20 4A 61 70 61 6E 65 73 65 20 54 65 78 74 21 00 00
"Hello Japanese Text!"

ERROR → exceeds 20 bytes

[What happens if overflow?]

➡ Overwrites next data block
➡ Breaks pointer alignment
➡ Corrupts file structure
➡ Game crash

Rule:
ALWAYS keep text ≤ (xx bytes)
Pad with 00 if shorter​

Reverse engineering is a true passion of mine, and all the scripts I develop are built to be fully ready for text editing and seamless reintegration into the game. :)​

I'm just a poor player who only play games other people translate and I stopped reading after a few lines, but I guess you've done a great work in making these tools and sharing them!!!

 

[sun0wl]

Not all heroes wear capes... I've always been curious about Venus & Braves in particular so I'm looking forward to messing with that ISO now haha.

It's not often that people release their tools, even when they don't intend to complete a project, which is a shame. You've done a real service for the community. Thanks!

Are you leaving the translation scene? Or focused on other translation projects?
