Guide to Creating the PSBBN 'bnupdate.tar.gz' Language Installer (Creating the file in 7Zip or a similar program MAY cause problems.)

[Emertels]

1 - Download and Installation
●Download the Standalone Installer from the official site: https://git-scm.com/download/win
●Why the Installable version: It is essential to choose the Standalone (installable) version because it automatically adds the right-click option to your Windows folders. This allows you to open the terminal directly in the correct location without typing complicated file paths.
●During the editor selection screen, choose: Use Notepad as Git's default editor.
●Why Notepad: The original editor (Vim) is based only on keyboard commands and does not support the mouse. If it opens, you might have trouble closing it. Notepad is the standard text editor you already know.

2 - Step-by-Step to Generate the File
●Go to the folder where your opt0 folder is located.
●Right-click on an empty space inside that folder and select: "Open Git Bash here".
●Before running the main command, you must move up one level so the system sees the opt0 folder from the outside. Type the command below and press Enter:
cd ..
●Now, type the main command to create the PlayStation 2 compatible file and press Enter:
tar --format=ustar -czvf bnupdate.tar.gz opt0

3 - Difference between Windows and Git Bash (ustar)
●Why Windows fails: Common tools (WinRAR, 7-Zip, or native Windows compression) create files with modern headers. The PlayStation 2 uses a very old Kernel (2.2.19) that does not recognize these new formats, which results in the Cannot open error.
●The ustar solution: The ustar command forces the creation of a file based on the 1988 standard. It is a retro format that the console can read perfectly.
●File size: The final file size will be slightly different from a compression made in Windows. This happens because the ustar standard organizes data and file permissions in a simplified way for legacy systems.

4 - Finalization and PS2 Usage
●Once the process is finished, the bnupdate.tar.gz file will appear in your Windows folder.
●Copy this file to the root of a USB drive formatted in FAT32.
●On the PlayStation 2, you can use Putty to send the commands or type directly into the console. When you run the bnupdate command, the system will now be able to extract everything without any errors.

NOTE! According to our friend @CosmicScale, the WSL has similar features.

If this is about creating language .tar.gz patch files, I had no issues creating them with 7zip in Windows and installing them by copying them to a usb stick and running bnupdate via putty.

Yes, that's it. But unfortunately I tried numerous times, our Hungarian friend also had this problem. So the solution for both was with Bash.

If you're using Windows, you could also make the tar archive using WSL, since you already have it installed.

Yes, I use Windows. I didn't even know you could do that with WSL; I don't know much about Linux. Anyway, I managed to do it perfectly with Bash. Because it's practical, maybe I'll only use Bash.

I added a note to this tutorial.

If you've installed PSBBN with the PowerShell script, you'll have an app called PSBBN in your start menu. If you run that, you'll be at a Linux command line.

Yes, yes. I know, friend. I just didn't know it was possible to do that. WSL installs along with it; I even opened it here now to check. WSL is very similar to Git Bash.
