Mystery Chronicle: One Way Heroics ".bin" Archives

[Rygdea]

Hey there. Any chance someone could help me extract/repack(?) these ".bin." Every "file" in the game is using it except Audio which I found out is using XACT very easily.

There are 33 of them and they range from as small as 4KB to 1GB, following the name format of "dataxxxx.bin" with an "archive.bin" sitting on top of it all.
I also know 4 of these is just actually a video file with the wrong extension which play fine in MPC. The rest with my minimal knowledge I looked at with a hex editor and they all had bin in the header except archive.bin/videos, that's all I understand.



I attached some of the tiny ones as samples, hopefully they all follow the same format.

Thanks for any help!

I forgot to say this game is on PC.

If it also helps this game was made by the same people as the Mystery Dungeon Pokemon games.

I suspect that all these files are xored (in total or some parts of them) with the bytes 0x10 0x41 0x52 0x21.
Anyway after the decryption it's still strange data without a format.

Thanks for looking into it aluigi. I don't really understand much of this but anything else I can help provide to help figure it out?

Game EXE?
I saw mention of Phyre Engine in the exe.

171MB archive?
QuickBMS Split of a 1GB archive?

Maybe the sample files I provided were something else as I can't really tell what they are except for their size since they are all hiding as "bin."

I'd be grateful for further assistance, either way thanks for your time.

I see no format, just "data" (no idea of what type of data):

Code: Select all

get SIZE asize
filexor "0x10 0x41 0x52 0x21"
get NAME basenane
get EXT extension
string NAME + "_crypt."
string NAME + EXT
log NAME 0 SIZE
