I am using the trial version of CE 7.1 on Mac.

The game that I was trying to modify is FM2020. Please take a look at the screenshot.

I only wanted to change one byte, which is the "64". However, I was enable to do so and I don't know why (I consider myself an experienced CE user on PC). I tried to change the page protection type to "Read Write" and every other type, the result remained the same. So I come here to seek for help. Thanks in advance.

PS: I have already disabled SIP on my system, if that matters.

I've seen this before yes but haven't got a sure solution yet

Try editing the game's app package and strip out the signature. That may disable the code integrity flag as well

Thanks for the reply.

I've got some follow-up questions:
1. Is this problem caused by the Mac system?

2. How to edit the game's app package and strip out the signature? Is it complicated? Can it be done by using CE?

BTW, I can change the values of the white colored memory, but not the green ones. I suppose the green ones are static memory? If so, does that have anything to do with this problem?

Thank you!

1: Seems so yes. It's a protection in the app's package information
2: You may be able to strip the codesigning certificate from the package, and then (perhaps) you have to edit the package info to disable that flag.
Not sure how to do that right now, but there are some tools that can help with that I think

It's likely some kind of code integrity protection in mac that still is active even when system integrity is disabled. Green code is module memory, which means it's more likely to be protected

Or I could be wrong and i'm just missing something, but it doesn't happen on all processes, so not sure

Thanks for the reply. I think I will give up for now. Very Happy

The beta of 7.2 on patreon fixes this issue
