Hacking Question Edit precompiled payload

[masagrator]

Is there a way to edit precompiled payload? For example I want to edit sx os loader to load boot.dat but with different name (bood.dat for example).
I couldn't find anything about deassembling/decompressing/anything else how to edit it.

Edit: oh, ok. Nvm. It uses Unicode strings.

Unless you know how to modify the binary itself (so just a bunch of 0s and 1s) or either you disassembly the binary and work with assembly instructions (load, move, add and so on), no, there isn't a way.
If the problem is extended to other payloads (hekate, atmosphere, rcm lockpick etc) then you can just edit the source, build and make your own payload

First issue is that payloads are using lz77. And ofc not whole file is using compression. So i can't just edit string.
I was thinking maybe there is already somewhere decompressor for payloads.

Even if you would be able to edit it, integrity checks will fail and payload won't boot (if we're talking about sx os payload)

I'm talking about SX OS Loader in bin format, which loads SX OS boot.dat
I don't want to edit boot.dat. I want to edit payload.bin.
Or it's the same issue for both?

Well, I guess it would be the same
