I did find a working version but can't confirm it is free of the malware that may or may not have been in the discord hacker version. All I can say is I have not noticed any issues.
There is a torrent of it on: bt4g(dot)org ( I can't post links here yet)
Search for "Captain Hardcore v0.10.1 {Cracked}"
Note: The crack is a bit different and the instructions are not quite right. This crack exe does not start the game, just generates the key file (Where did the keys come from? Is this a keygen? Are any of them Asstronaut keys? I have no clue).
1. (only needed if you tried the old crack) clear out any "captain hardcore" or "fluidGame" firewall rules.
2. run the crack exe.
3. run the normal game exe.
4. start trying keys from the key file. Once you get a working key QUIT, DON'T ENTER. Note: If you can't clear the key field to try a new one, remove the game save at AppData\Local\FluidGame\Saved\SaveGames (google "appdata" if you don't know how to find yours).
5. Run the block connections bat file.
6. You can now play the game with the normal exe.
Use at your own risk. If anyone can give it a better once-over than a standard virus scan, please report back and let me know if I gave my pc space aids.
