Compiling / Decompiling lua byte code

Compiling / Decompiling lua byte code

so I have a script in bytecode which I need to decompile. The script is a
very long one so I've put it [url=http://wklejto.pl/169767]here[/url] so
the post doesnt turn very long. Anyways, I am able to decompile the byte
using online lua executors such as
[url=http://www.compileonline.com/execute_lua_online.php]this one[/url] to
execute [url=http://www.wklejto.pl/169768]this[url] script and I get the
code I want but theres also alot of different stuff in it like EOC DC3
NULL etc, but I am able to edit the part I want so after doing so I try to
compile it using the executor mentioned above and
[url=http://www.wklejto.pl/169769]this[/url] script but I am getting
errors which do not allow the script to be compiled. The error I am stuck
at is [code]unexpected symbol near char(27)[/code]
So now, my question is, could anyone please show me a different, 100%
woring way to decrypt and encrypt the bytecode or help me to encrypt it
with the method I am currently using?
Thanks in advance.
P.S. I know very little about coding etc so please, in your answer give me
tips that a newbie like me will understand.
