Bloodborne v1.09 -DLC Mods- -CUSA00900: The Ultimate Hunter's Guide

It’s been years since the 1.09 update dropped, but for the modding community, this specific version remains the definitive way to experience Yharnam with a twist. If you’re looking to get mods running on your CUSA00900 copy, here is the current state of the scene.

The Lance McDonald Patch

: In February 2021, modder Lance McDonald released a legendary unofficial patch. It didn't just unlock the frame rate; it utilized a "Deltatime" fix to prevent the game's physics from speeding up at 60 FPS—a breakthrough that required reverse-engineering the game's core engine.

Released in late 2015, v1.09 fundamentally changed how hunters prepared for the "Old Hunters" DLC.

Never update your game

The cardinal rule: . If you own a digital copy of CUSA00900 and it’s already on 1.09, block updates via your router or DNS. If you own the disc, delete the install, reinstall offline, then patch manually to 1.09 using a USB drive. Any newer patch does not exist—but Sony’s servers could theoretically push a 1.10 (extremely unlikely) that would brick every existing mod.
