How about 64 bit app ?

Yeah, that's one problem with assembly. You have to write it twice for x86 and x64. Hence the invention of languages where you can compile an x86 dll and an x64 dll from the same source (if it's trivial or you coded it properly)

Though I didn't actually realize you could refer to labels with "s around them lol

anyways, here's an x64 version

lol Free, thanks for that.

dQuotes dont mean anything in CE, i just used them them for visual purpose.

you can say:

db "00" "01" "05" "19"

or anything really haha, so yeah visual purpose.

Thanks FreeER...great job., but
found an error :

line 15 : (move r9, 4) : This instruction can't be compiled

@Corroder Make sure you're attached to a 64 bit process because "mov r9, 4" is certainly a valid instruction (and if you search for "move" you'll find it's not in the script so it's not that typo either lol)

update:
- added 3 different sounds, each box have one.

Well now that's kind of begging for something more flexible lmao

note: this will save CE's default activate and deactivate sounds to your "My Cheat Tables" folder, they're the only wavs I felt I could guarantee having access to (and I wanted to demo that actual file paths would work, not just a few system sounds).

Also note that it requires loading a library, at least for the tutorial. Not sure how common winmm might be lol

lol awesome, it loads windows shutdown sound.
i could create custom sounds tho, but it will be waste of time.

Is there any kinda of standard way to hook a processes GUI/Forms library, or would you need to know the libraries api and/or reverse a given library.

OldCheatEngineUser · Jul 26, 2020

reversing a library takes lot of time since every function call other functions from other libraries, and at the end of this calling process most of the functions call kernel library and ntdll.

but i believe knowing the libraries and api's is enough tho, you still can create your own libraries and/or use other libraries for gui things.

about creating forms or dialogs in other running processes, as long as that process created an entry point in that specific dll then you can hook their functions.

(this is what i know so far, so maybe someone have more technical details than me)

(disclaimer: I really haven't messed with gui stuff, it's rarely of any interest to me beyond visually looking for clues as to the values I should scan for)

You'd definitely need to figure out the GUI API/Library used. Most large games don't use one. Well, they do but they roll their own or it comes with the game engine which is probably custom made. Even when they do use something they'll likely customize some of the functions to fit their needs so that can occasionally change things Smile

But if they happen to use a library where you have access (to at least the documentation), then you should be able to create a dll based on that and inject it into the process (probably have to use function pointers rather than relying on the linker/windows to replace addresses for you on load though), and if you can do it in a dll you could eventually do it in asm if you so desired lol Smile

strlen and stricmp would be a good addition Very Happy
