What Did “Adds 18” Actually Do? (Technical Explanation)

From reverse-engineering reports on older cracking forums (now defunct), the “adds 18” patch likely worked as follows:

The original vegas110.exe contained a jump instruction that checked online activation status.
The crack replaced 6 bytes of assembly code with a jump that skipped activation.
However, to maintain file size alignment, the cracker appended 18 null bytes (or 0x90 NOP instructions) at the end of the .rdata section.
Hence the patch was labeled “adds 18” – referring to the hex edit offset or added bytes.

This is not an authentication code. It is a binary patch that disables license verification. Modern anti-virus software flags such patches as generic malware.

What Does “Authentication Code” Mean in Sony Vegas Pro?

When you install Sony Vegas Pro 11 (or any commercial software), you are required to enter a unique 20- to 25-character alphanumeric license key (often grouped as 5 blocks of 5 characters). This key is validated either online (activation) or offline (via a generated response code).

An “authentication code” generally refers to:

The original serial number purchased from Sony.
The offline activation response code generated by Sony’s servers.

A keygen (key generator) illegally mimics Sony’s algorithm to produce valid-looking serials. The phrase “adds 18” likely refers to a specific keygen version or a patch that modifies the .exe to bypass activation – sometimes by adding 18 bytes of hex code.
