This report provides details regarding the specific software release identified as VB.Decompiler.Pro.v9.2.RETAIL.BY-1ST.INCL-PORTABLE. Overview
VB Decompiler Pro is a specialized reverse engineering tool designed to decompile programs (EXE, DLL, or OCX) written in Visual Basic 5.0 and 6.0, as well as those based on the .NET technology. The version in question, v9.2, is a legacy retail release that was historically distributed through third-party release groups. Release Information Version: 9.2 (Retail) Release Tag: BY-1ST (attributed to the release group "1st")
Distribution Type: Portable (does not require a formal installation to run)
Includes: Typically includes the retail binary and a pre-activated or patched portable wrapper. Key Features of VB Decompiler Pro
VB Decompiler is widely used by security researchers and developers for analyzing legacy software. Its primary capabilities include:
P-Code Decompilation: It is one of the few tools capable of decompiling Visual Basic "P-Code" into readable assembler-like instructions or high-level code.
Native Code Support: For programs compiled in "Native Code," it provides a powerful disassembler and an emulator to help reconstruct the original source logic.
GUI Restoration: It can extract and reconstruct the forms (.frm) and controls used in the original project.
.NET Support: It includes basic decompilation and analysis for .NET-based assemblies. Historical Context & Security Risks
The specific string VB.Decompiler.Pro.v9.2.RETAIL.BY-1ST.INCL-PORTABLE is a standard naming convention used in "warez" or file-sharing communities.
Legacy Status: Version 9.2 was released several years ago. The official software is currently at much higher version numbers (e.g., v12+), which offer significantly better support for modern Windows environments and advanced obfuscation.
Security Warning: As this specific "Retail BY-1ST" version is a cracked or modified release found on unofficial sites, it carries a high risk of containing malware, backdoors, or bundled adware.
Stability: Portable versions created by third parties may lack the necessary runtime libraries or registry entries required for full functionality on modern versions of Windows (10/11). Recommendations
If you are performing professional malware analysis or software auditing:
Use Official Versions: The official VB Decompiler website provides trial versions and legitimate licenses that are safe and up to date.
Sandbox Execution: If you must use this specific legacy version for a niche compatibility reason, always run it within a Virtual Machine (VM) or an isolated sandbox to prevent potential host system compromise.
The rain over Riga came down in digital sheets, slicking the cobblestones outside Ivars’ attic window. Inside, the glow of three monitors painted his face in cold blues and whites. On the center screen, a blinking cursor waited next to a familiar prompt:
`C:\Users\Ivars\Desktop\VB_Decompiler_Pro_v9.2_RETAIL_BY-1ST>
The folder was a ghost. A self-contained universe compressed into 47 megabytes. No installer. No registry scraps. No phone-home telemetry. Just an .exe and a single .dll with a timestamp that read 1999-04-12 04:08:22—the hour the original developer had probably last slept well. VB.Decompiler.Pro.v9.2.RETAIL.BY-1ST.INCL -PORTABLE
Ivars wasn’t a cracker. He was a forensic historian. His specialty: digging abandoned Visual Basic 6 applications out of corporate shallow graves. Factories, banks, old medical devices. Programs whose source code had been lost to a crashed server in 2008, whose only remaining author had retired to a fishing village in Thailand and stopped answering emails.
Two weeks ago, a hospital in Liepāja had called. An infusion pump scheduler—written in 2002 by a subcontractor named “Baltsoft”—keeps throwing error 457 (Duplicate Key) every night at 3:14 AM. No source. No support contract. The pump stops, and a nurse has to reboot it by hand.
The hospital’s IT director: “Can you… look inside?”
Ivars had nodded. Then he’d spent ten days searching torrent archives, old FTP mirrors, and a private forum where usernames like 1ST still commanded respect. And there it was. A 2013 release. The legendary VB.Decompiler.Pro.v9.2.RETAIL.BY-1ST.INCL -PORTABLE.
He double-clicked the .exe. No UAC prompt. No splash screen. The window opened instantly—raw, gray, utilitarian—like a scalpel laid on a steel tray.
He dragged the hospital’s pump_sched.exe into the decompiler pane.
Three seconds later, the Forms tree unfolded. There was frmMain. tmrHeartbeat. A module called modDosage. Then he opened the decompiled code pane—and froze.
Most VB6 decompilers gave you pseudo-code. Gibberish labels. Jumps you had to trace by hand. But this version—the 1ST release—did something else. It reconstructed original variable names. Comments. Even the folder structure the original dev had used.

REM 2002-03-17: Jānis fixed off-by-one error in AM shift
Ivars felt a chill that had nothing to do with the rain.
He found the modDatabase module. The error 457 was being raised in a Collection object—something about adding a duplicate shift key. But the root cause wasn't in the pump logic. It was in an obscure WriteLog subroutine that, when the log file exceeded 2GB, tried to write a duplicate entry into an in-memory cache.
He fixed it in twenty seconds. A single If Not colCache.Exists(strKey) Then before the Add. He recompiled using the portable toolchain the decompiler had extracted—no need to install VB6 itself.
At 2:47 AM, he emailed the patched .exe to the hospital. “Test at 3:14 AM. Should pass.”
He closed the decompiler. Then, on a whim, he opened its own About dialog. A single line of text appeared:
VB.Decompiler.Pro.v9.2.RETAIL.BY-1ST - "The source is never lost. Only forgotten."
Below it, a tiny button labeled Credits. Ivars clicked it.
A Notepad window opened. Inside was a list of seventeen names. No handles. No emails. Just first names and years. The last line read:
Janis (Riga) – 2013. If you're reading this, you're one of us now. Pass it forward. This report provides details regarding the specific software
Ivars leaned back. The rain had stopped. Outside, a streetlamp flickered once, then steadied. He looked at the folder on his desktop again.
He didn’t upload it to a public tracker. Instead, he copied it to a USB stick labeled TOOLS_ARCHIVE, locked it in a fire safe next to his birth certificate and his grandmother’s silver watch.
Because some tools aren't just software. They're handshakes across time—a way for one generation of forgotten-system keepers to tell the next: Keep going. The machines still run. And someone still needs to read what we wrote.
At 3:14 AM, his phone buzzed. One line from the night shift nurse:
“Pump passed. Thank you.”
Ivars smiled, shut the laptop, and went to sleep while the hospital’s infusion pumps whispered their steady, perfect rhythm into the dark.
