Amazing ,looks so easy (methinks) when watching you do it.

Though i doubt very much i could do that :)

Very clever.

A user recently bought ACS Standard Edition, and is (was?) not able to activate the 'killthread' script. The mem/code_location was (obvioiusly) different in that the "jump sits isolated" here...
Anyways: tried to follow #Sunbeam's routine again, but ran into trouble: any attempt to attach CE's debugger or x64dbg's (w/ Scylla plugin ~ vmprotect profile) failed each time; game crashes pretty much instantly?! Since I knew what to look for, took following approach:
1. Using CE, find the "offending" threadID: [ [Link] ]
2. Using ProcessExplorer, kill that thread: [ [Link] ]

ps: I rarely come/came across a game, that CE could not handle. Point in case: ACS Gold does not give any problems at all...? If anyone would be challenged to find a way around this, here is the EXE Standard Ed v1.51: [ [Link] ] (which does not support the DLC (and such)
If you can get x64dbg attached (and running) as well, I would like to know the details too (euh, pretty please 8-) )...

Ahum: awaiting your script...


First-up, use @ in front of a name, if you want to notify them in (which is a Discord feature, in case you didn't know). Secondly, I don't get the statement, if a joke or not, nor when I said that (that he's from Mars). Do remind me, perhaps the context eludes me currently.



In short.. at the time I made the video, I didn't think of any ways to do it from CE. Not to mention how old and not sought-for is this game. So the x64dbg method would suffice. Now that I've read this.. and I remember I wanted to make a CE plugin that allows you to bypass stuff directly upon enabling it.. and didn't work out fine.. I thought "why not give this a go?" :) So there you have it.
Wait, so in the end you CREATED the script? Cause I can't find it, or maybe I just don't know what I'm searching for, I'm just overwhelmed with all these information D:
