Hacking Extract scripts from a PSP VN (.bin format)

[Gaikonaiko]

Hello,I want to extract scripts from a PSP Visual Novel,but the scripts (script.bin) are in the .bin format.
Can anyone help me please ?

mentioning the game name might be a good start

Ah, that's true
The game is Da Capo I&II Plus for the PSP.
Sorry for the late reply, I didnt think someone would answer me ^^

here you go, it's not awfully complicated of a file.

Thanks for your help ^^
So,if I understand,I must edit it using a hex editor and that's it ?

the above image i posted explains the structure of the bin file.
extract it using that information to get out the .obj files that are inside the bin.

i didnt look at it much but it seemed that the obj files contain a bytecode section at the start, and the text script after, shouldn't be too much of an issue to figure it's layout, but i'd suggest you start by creating a tool to extract and rebuild the bin file before going further with it.
