hi. i have been using CE over 10 years and never had this issue before.
i made simple hacks for game that i play and saved the list. i have been playing for 3 days and table has worked just fine. game have not had any updates and its single player only.

today i load up the game and table as always and only 1 out of 5 hacks i made works, rest dont enable. CE freezes for few seconds and nothing happens.

so i manually searched for the instruction and used auto assembler > template > AOB injection (this is how i always write my hacks) and it auto-generates injectable code. i didn't modify it and pressed "execute"

then i get error "failure allocating memory near xxxxxxxx".



i then searched on google and found only 1 topic on ce forum about it, but it wasn't exactly same as my issue. someone there mentioned something about "mono game", which i have no idea about. never heard of this before, it must be some "next gen" memory allocation system or something?
anyway NOT important, at this point i'm not interested to learn what mono is.

i just wanted to say that in CE i enabled mono features and then the addresses in memory view changed. instead of .dll or .exe names, i now see game-related terms, like "helmetoff.gui" something.

so i thought i try once again with mono enabled and i repeated the first steps again. i used template and > AOB injection, it generates code and when i click on "execute" i now get this error:


code on image is generated by CE, why does it generate code that cannot be injected? i thought whole idea of template is that it generates fully working code like without mono features? is CE broken, is this some known bug?


all i need to know, is how to fix this. how can i inject my code again?
why was it working for 3 days and all the sudden it stops working?
i did notice that my RAM usage was around 92%, i'm not sure but i dont remember seeing it that high before when playing this game.
could it be that memory is simply full and that causes the error? if so, how do i bypass it? how can i force CE to free up memory?
please note that i'm not expert at coding so please dont say something like "write your code here > jump there > blah blah here > done". i need fully working example that i can copy, paste and then slightly modify. if i was expert programmer i would not be asking help here. thank you

"Failure allocating memory near XXXX" sometimes (maybe most of the time?) means there's no free memory near that address. Go to Memory Viewer -> View -> Memory regions and see what's around that address.

See the final part of this post that says "In rare cases, `alloc` might fail..." for more information:
https://forum.cheatengine.org/viewtopic.php?t=620587

Post the code around the injection point if you want more help. (the big comment at the end of the AOB Injection template is good).

for the je instruction being bad, try

Memory layout is random. Helps protect against certain kinds of attacks.

That's not the same script. The injection point is completely different.

Do you know what a virtual address space is? If not, start with that.

By "memory layout is random", I mean memory will be allocated to a random address by default. In this case, sometimes there might be a small gap where CE can allocate memory, and sometimes there may not be.

This is the original code in your first post:

It seems to me like you want others to teach you how to fix this yourself, but you don't want to spend a lot of time learning and researching the relevant information. Again, if you want someone else to do this for you, be more direct about it and try asking elsewhere. i.e. a third party site:
https://forum.cheatengine.org/thirdparty.php

All the information you need is already available to you. Most of it being in this post:
https://forum.cheatengine.org/viewtopic.php?t=620587

The rest can be found by using a search engine.

As a brief overview: it's convenient if the memory CE allocates for a code injection is near the injection point. If there is no free memory near the injection point, that fails. Sometimes there might be free memory, other times there might not be. It's up to how Windows decides to randomly allocate memory.
Work around this by using `jmp far`. See the linked post.
