Awakenchan/LanternEngine

Lantern Engine targets people who own a PS4 copy of Bloodborne and want to play it on a PC without a PS4 in the loop. Download the release, point the launcher at your dumped game folder, press Play, and the game boots. It is a niche, legally constrained project, and the setup work happens before you ever open the launcher.

The problem

You own Bloodborne on disc or digital, but the only official path to play it is a PS4. You want the game running on your Windows or Linux machine with a controller and a PC-shaped settings screen. The usual friction is not the launcher itself but the prerequisite: you must dump the game (CUSA03173, update 1.09) from your own console. Once that folder exists, the launcher asks for it and starts the game; the interesting part is that this does not emulate the CPU.

What's different

The README describes a launcher plus engine derived from bbport and shadPS4, with the game's own code running natively on the CPU and its graphics translated to Vulkan. The author lists concrete rework on top of the base: native shader compilation, direct draw calls, pipeline and memory performance work, PC menus and controls, upscalers (FSR 3.1/FSR 4 on Vulkan, DLSS), cheats, occlusion culling and trophies. The launcher also self-updates and can register Bloodborne.exe as a non-Steam game.

The trade-off is that this is one maintainer's reworked fork of other people's work, not a polished port. The README itself says updates have slowed because of the hate the author has received. It also depends on a chain of upstream projects and third-party components (FSR, DLSS, LibAtrac9, ImGui), each with its own license, so bugs may come from several layers at once. Linux support is labeled beta and needs Python 3 plus glibc 2.38 or newer, which rules out older distros unless you upgrade.

Who should try it

A good fit is someone who already has a working dump, a Vulkan-capable GPU, and patience with a project that is explicitly in flux. On Linux, it may make sense if you run Ubuntu 24.04, Fedora 39, Arch, SteamOS 3.6 or Bazzite, because those meet the glibc requirement and ship Mesa or NVIDIA drivers. The documented alternative on Linux is launching ./lantern.sh /path/to/CUSA03173 from a terminal rather than using the GUI.

A poor fit is anyone without a legal dump, or anyone expecting console-free setup. The README states plainly that no game files are included, so there is no demo mode. It is also a weak fit for players who need a stable, support-driven experience; the author is solo and says the pace has slowed, and bug reports go through a Discord #issues forum rather than a structured tracker.

Requirements and limitations

Windows users download a zip and run the executable. Linux users need a Vulkan driver (Mesa or NVIDIA), Python 3, and glibc 2.38+, and DLSS Super Resolution works only on RTX cards with NVIDIA's driver; DLSS Frame Generation is Windows only. The game itself must be your own dump of CUSA03173 with update 1.09, which is the largest practical hurdle and the one no launcher can remove.

The license adds upkeep obligations for anyone who redistributes or modifies it: GPL-3.0-or-later with additional terms requiring the credit "Lantern Engine by Awaken", notice that changed versions are changed, and no reuse of the name. Personal play is unaffected, but forks and repacks are not free to strip attribution. Ongoing care means tracking launcher updates and checking the project's Help & FAQ when graphics settings or crashes appear.

HotRepo's take

HotRepo's only dated observation is a #7 rank on the NEW-REPOSITORY board (新项目榜) in the cpp language filter, observed 2026-10-25, with 999 total stars. That is not a daily growth measurement and the tracked window spans just two recorded dates, so persistence cannot be judged. Before committing, read the project's setup and troubleshooting pages; that is the fastest way to confirm your specific GPU and distro are covered.
