PureBasic Forums - English

Hi,

I used VM in the past to protect code and it works well (Code Virtualizer).

Now i found that someone could creatre something like a VM in Purebasic. Has anybody tried this before?
250 lines of code says in this article

Thanks in advance

You can port this easily, but ...

What do you want with a LC3 'computer'

To virtualize like Code Virtualizer that makes difficult to crack the software.

I think if you write the code in LC3 assembler it is 'unhackable'

Is there a C compiler for LC3 ?
Else you have to write all your code in assembler

No, but i dont know assambler.

Its not possible to code a VM in PB and use it in my program to make it difficult to crack?

You can use the free tool "Enigma VirtualBox"

Or better "Enigma Protector" (commercial) if you really need a real protection system

I have used both and they work great.

Thanks, but it looks like it can be done within PB.

Anybody can help with this?

There is a comprehensive tutorial on the German PureBasic site:

Tutorial in German
Discussion in German
Code of scanner, parser, assembler, virtual machine.

The code is fairly old (2013), so you would have to adapt it to the newest PureBasic version.

But at least you get the idea...
