I’ve used these for years to fuck around/experiment with games I’ve played to excess (single player games with no ranking/etc/etc where my screwing around could give me any kind of advantage, to be clear), and had no problem getting it running/doing what I want…

Until recently… The only thing that changed was that my OS (Nobara, Fedora based) updated from 42 to 43, and now suddenly Cheat Engine (used via steamtinkerlaunch) and PINCE (Native linux cheat engine-alike) stopped working. Even on old games I successfully used them to screw around with in the past. Yes I select the proper process.

Memory View shows nothing but question marks, value searches that used to work fine don’t return anything anymore. Like, it can see the process, but has no access to muck around in the memory itself… Since it happened with an OS update, I can only assume that something changed in the backend thats interfering with these things running, but I’m not a Sysadmin/IT specialist, I’m just a random user, so I’ve tried to figure this out myself via internet searches and the like, but I’ve come up blank on everything I’ve tried.

Anyone else out there with a similar experience who could provide some aid on the issue?

Thank you for reading.

    my ptrace_scope file has 0 set inside it, which i assume is the least restricted from what i’m understanding and shouldnt be causing the issue?

    but just on an off chance i tried to run the echo command, and even with sudo it says i dont have permission. so I dont know whats up with that.

    I’m an idjit and realized PINCE is a gui for a CLI command, so I quickly loaded up a game just to do a quick value search to get the results and this is the error

    [___](info: 399 suitable regions found. ......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................warn: reading region 00 failed. warn: reading region 00 failed. ..............................warn: reading region 00 failed. warn: reading region 00 failed. ................................................................................................................................................................................................................................................................................................................................warn: reading region 00 failed. ..................................................................................................................................warn: reading region 00 failed. ....................................................................................................................................................................................................................................................................................................................................................info: we currently have 14 matches. )

    I think that region 00 failed is the problem.

      Yeah, then that restriction isn’t the problem. Sorry; I guessed wrong.

      but just on an off chance i tried to run the echo command, and even with sudo it says i dont have permission. so I dont know whats up with that.

      It won’t help here, but for future reference, what you likely did is this:

      $ sudo echo 0 >/proc/blah/whatever

      sudo runs a command as root. The file redirection, however, is done by the current shell, which isn’t run as root, not by echo. So echo 0 is run as root, and then bash tries to open /proc/blah/whatever and doesn’t have permission to do so, and that’s what fails.

      If you need to do this in the future, you can do this:

      $ sudo -s
# echo 0 >/proc/blah/whatever

      we currently have 14 matches

      It might be okay to hit that, as I don’t know if scanmem avoids trying to scan all regions that it can’t read. That does mean that it is able to ptrace() it and find some matches. Did you try to keep going with additional searches to see if it could actually find the value and change it?

        Gotcha, thanks for the tips on that first part.

        As per the last part, It apparently can sometimes find the initial value, but not any changes in the value. That CL snippet I posted before was the first time it found the first value i entered, but crapped out and found nothing on any followup changes to that value.

        Its not like its a big deal, Ultimately its just me futzing around in old games for my own enjoyment, its not like I’m critically losing anything… Just weird that it suddenly stopped working when I updated, especially when you highlighted a thing it should have most likely been… and that not be it.

        I appreciate you spending your time to write these large and informational replies, Thank you, they are helpful even if not on the immediate situation :D
