Help with the Persona 5 - Strikers file. #33

Closed Digote closed 1 month ago

Digote commented 1 month ago

First of all, congratulations on your help to the community. I've been following your repository.

I'd like to see if I can get some help or a path to finding a solution. The game Persona 5 - Strikers made by Koei Tecmo uses the Linkdata.idx + LinkData.bin pattern, but it seems to be in a different way. The IDX file seems to be inside the game's .exe file, and besides compression, there also seems to be encryption in the .bin file. I'll leave a tool here that worked until a few builds ago but stopped working.

Here is a pull request where someone managed to locate the key. https://github.com/yretenai/Cethleann/pull/36

I'll also leave a link to the .exe and the LinkData.bin file:

LinkData.bin

Thanks

Hi.

Thanks ;3

I've never really worked too much on reverse engineering Koei Tecmo formats. The're still a mystery to me, so I'm unable to support extraction from BIN/IDX without serious RE work like debugging the game etc.

You should ask about it on ResHax forum https://reshax.com/ and on resHax discord server. Maybe someone else will be able to help with this case.
