I tried to run RSInjector and nothing happens. HELP! 😃

Thanks in advance.

Same here. Just happened to me today 10.4.16

Same here, RSInjector runs but doesn't open the RS, the script just stop.

Is there any workaround?

[Firekorn]

The app changed and the signature isn't correct anymore and none of the dev that worked on it for the remastered update seems to be here so it's a bit more complicated for other user to come in and inspect the code of the new app.

@0x0L or @fabianosan Any help would be appreciated here!

I had a quick look unfortunately I don't own any professional tools for code analysis.
It seems they decided to screw us a bit: can't attach a debugger anymore, can't use naive dylib injection, etc...

If anyone has the old binary I would be great to share it somewhere

[Firekorn]

The old binary are available here : https://www.dropbox.com/sh/uvm9ws9x833rj8q/AACFsCC7z8kdZu7tf12TQUP2a?dl=0

@Firekorn
Thanks mate

They updated lib_steam too

The file is too big for Hopper Disassembler to parse over demo time (half an hour). They did actively seek to prevent us from debugging or injecting code.

I really don't have time to spend on this right now, sorry guys

just sayin'

@haxnyc I certainly won't support stealing other's people work

[Firekorn]

@0x0L here's a dump of the memory from the new version of the app if you wanna do your own search and also update the project (i am nowhere near knowing how to manage all of that) https://drive.google.com/file/d/0B1ZKYtpB0vu2bUFOamhDM3FlWXM/view?usp=sharing

Hopper for what it does seems very reasonably priced, I just bought a copy so like I said I can try and learn a thing or two about reversing OS X apps.

Likewise for Rocksmith, I've already bought tonnes of DLC, but I only discovered CDLC a few weeks ago, only to now find it's possibly no longer a thing. Guess I was late to the party :(

[Firekorn]

@benneh it's far from too late i've shared the dump with someone that worked on the dll for PC and even though he is using a VM to compile the code, a somewhat decent result can be expected sooner rather than later. The more people are knowledgeable of those app the easier it will be to react to any new update.

[Firekorn]

I'm not sure what's going on on my end as i never tried to play Rocksmith with CDLC on my mac but i can't get the RSinjector to launch Rocksmith after compiling the code to bypass what's at the address 0x1ccb85 anyone with actual knowledge of this code could come by and share his light would be greatly appreciated as i'm really not sure what the hell am i doing!

[benneh]

Likewise, fumbling my way through this :)

Where did you get the address 0x1ccb85?

Looking at the previous version it was overwriting the check by looking for the opcodes: \x84\xdb\x0f\x84\xde\x0a\x00\x00

This can be found at 0x1cbed5 and was the following instructions
001cbed5 test bl, bl
001cbed7 je 0x1cc9bb

This was just replaced with 0x90, (NO OPs) to skip over the code segment.

How we go about locating the same code segment in the new one is where I am struggling?
