PSBBN Definitive Patch v4.0: OSDMenu, support for 3rd-Party HDD adapters with HOSDMenu and more!

​

https://github.com/CosmicScale/PSBBN-De ... lish-Patch

NEW! OSDMenu MBR:
Replaced Sony’s original MBR application with OSDMenu MBR, a homebrew alternative that:

• Handles launching games and apps directly instead of relying on BBN Launcher (BBNL)

• Improves boot speed

• Games now launch up to 6 seconds faster

• Eliminates the need for the PlayStation 2 Basic Boot Loader (PS2BBL) — OSDMenu MBR natively supports launching ELFs by holding a gamepad button at startup, drastically reducing boot times compared to PS2BBL

• PS2 Linux is now booted directly by holding `circle` at power-on instead of interrupting PSBBN startup

• Removed the "Launch Disc" app — simply insert a game disc to play, with support for Game ID, MechaPwn and built-in PS1VmodeNeg!

• Improves Retro GEM Game ID handling — PSBBN and HOSDMenu now both set a Game ID on boot, removing the need for the Retro GEM Game ID Resetter

• When using a MemCard Pro 2 or SD2PSX, unnecessary VMCs are no longer generated when launching PS1 games with POPStarter or other homebrew apps

NEW! HOSDMenu:
Patches HDD-OSD and introduces several improvements:

• Supports larger drives — previously limited to 1 TB

• Launch homebrew apps directly from the OSDSYS menu

• Launch SAS-compatible applications from Memory Cards and from the internal drive in Browser 2.0

• Support for launching applications from MMCE, MX4SIO, UDPBD, iLink devices and APA and exFAT-formatted HDDs

• Integrated GSM for disc games and applications

• Support for 1080i and 480p

• And more — see the GitHub repository for full details: https://github.com/pcm720/OSDMenu

NEW! Install PSBBN and HOSDMenu:

• The PSBBN Installer now installs HOSDMenu alongside PSBBN

• Shows latest release notes when installing and updating

• Supports smaller drives — minimum capacity reduced from 200 GB to 32 GB

• Increased max APA partition size to 112 GB

• After partitioning, any unallocated space is now assigned to the OPL partition

• Advises users to check archive.org or use a VPN if downloads fail

NEW! Install HOSDMenu only:

• Adds an option to install HOSDMenu only (for users with third-party HDD adapters)

• Create a custom-size POPS partition (up to 118 GB), automatically assigning remaining space to the OPL partition (up to 2 TB)

Game Installer:

• Game Installer now requires PSBBN Definitive Patch v4.0.0 and above or HOSDMenu-only

• Adds support for HOSDMenu-only setups

• Updates OSDMenu MBR and HOSDMenu if newer versions are available

• Updates the Navigator Menu with shortcuts to your selected game launcher (OPL or NHDDL), HOSDMenu and wLaunchELF_ISR

• Updates the HOSDMenu config to display installed homebrew apps in the OSDSYS menu

• Automatically converts PS1 `BIN/CUE` files to `VCD` and PS2 `BIN/CUE` file to `ISO`

• PS1 games are now copied and synced through `PFS FUSE` using `rsync`, with visible progress during transfer

• Copies only valid game and homebrew files when syncing or adding games and apps — `rsync` now ignores Windows `:Zone.Identifier` metadata files that could cause sync failures

• Automatically capitalizes lowercase `.VCD` extensions to ensure compatibility with POPStarter

• Relocated `OPNPS2LD.ELF` and `nhddl.elf` to `__system/launcher` and `POPSTARTER.ELF` to `__common/POPS` from exFAT

`list-builder.py`:

• Now scans the PFS `__.POPS` partition for `VCD` files instead of local `POPS` folder

`art_downloader.py`:

• Converted `art_downloader` from JavaScript to Python, removing dependencies on Node.js, npm, Puppeteer, and Chromium

Install Music:

• Adds support for multi-disc albums using disc numbers from metadata

• Uses Album Artist metadata for albums, and Artist metadata for individual tracks

• Replaces unsupported characters in metadata with safe alternatives

• Clearly groups skipped files by reason

PS2 Linux Installer:

• Updates OSDMenu MBR config to enable the booting of PS2 Linux.

PSBBN Launcher for Windows:

• Minimum disk capacity reduced from 200 GB to 32 GB

• User prompts are now more descriptive

• Prevents users from selecting a WSL folder to store their games and media

• Enforces build 19041 as the minimum Windows version required to run WSL

• Runs `wsl --install --no-distribution` to ensure WSL 2 is available

• Explicitly uses WSL 2 when installing the PSBBN distribution

• Checks that apt successfully installed git; exits gracefully otherwise

• Updated disk number input to support values greater than 9

• Gracefully exits if disk mounting fails

NHDDL:

• Updated to version v1.2.0

`Setup.sh` and `flake.nix`:

• Added `bchunk` to dependences

Definitive Patch 4.0.0 Tar Archive:

• Fixes file permissions and ownership

• Removed cached files and other unnecessary bloat, reducing the archive size

• Removed `PS1VModeNeg.elf`

• Changes locale setting from `en_US.UTF-8` to `C.UTF-8` (some systems lacked `en_US.UTF-8`), ensuring script output and logs remain in English and preventing related failures

• Improved handling of mounting and unmouting APA partitions

• Bug fixes

• Added software licences
