Checklist (we expect you to perform these steps before opening the issue)

  • I have searched for a similar issue in this repository and did not find one.
  • I am using an official build obtained from releases or updated one of those builds using its in-app updater.
  • I have re-dumped the game and performed a clean install without mods and the issue is still present.
  • I have disabled all patches and cheats and the issue is still present.
  • I have all the required system modules installed.

Describe the Bug

Game Name : Bloodborne™ The Old Hunters Edition
I tried the methods I found online for similar issues, like increasing virtual memory, lowering the resolution, and applying various patches to reduce memory (VRAM) accumulation, but nothing worked. I had no choice but to come here for help. This save file already has 40 hours of playtime, and it would be really frustrating to give up now...

Reproduction Steps

After loading the save, the game crashes on the description screen and fails to start.
You can enter the game with a new or old save file, but only the save file with (Character Name: L) cannot access the game.

Look for the issue on your side. I was able to load your save without a problem.

找找你这边的问题。我顺利加载了你的存档。

Can the save file for character L also successfully enter the game? Could you please let me know the version of the emulator you are using and your computer specifications? I am using the pre-release version 2025.12.1 e5f9280

I'm using the latest pre-release, 16G RAM + 16G Page file, 6G VRAM, the rest of it shouldn't matter.
As for the save: yes, L character loads fine at the Mensis Nightmare lamp.

请问您使用的模拟器版本和电脑配置如何?

我用的是最新的预发布版本,16GB 内存 + 16G 页面文件,6G 显存,其他内容应该无所谓。至于存档:是的,L角色在门西斯噩梦灯下加载正常。

Okay, thank you for your reply. It seems I can only check for issues on my end.

What version of Windows do you have? I see it's 10 Pro, but which edition? 22H2? I'm not sure, but that could have had an impact on something as well.

[Core] address_space.cpp:136 Impl: Older Windows version detected, reducing user max to 0x10000000000 to avoid problems

You are also missing modules.

[Loader] emulator.cpp:526 LoadSystemModules: Can't Load libSceNgs2.sprx switching to HLE

Also your log has an error at the end:

While Bloodborne is known to have vram issues, your problem is different.
That assert in your log shows your GPU drivers are crashing. With Bloodborne, we usually only see this from modded games, though it could also be related to how old AMDs drivers for Vega GPUs are, or due to other issues with your device.

We generally don't provide support for hardware configurations a vendor stops supporting, especially for older hardware like your GPU.

I re-extracted the game once. At first, it still didn’t work, but later I lowered the resolution to 720p and 30Hz, and I was able to enter the game. In the early stages of the game, there will be a group of monsters that release a full-screen AOE attack that hits both enemies and allies at the beginning, and it’s continuous. Every time they use this skill, I feel a slight lag, and it’s worse when there are more monsters. I don’t know if this increases the load on the graphics card or causes memory (VRAM) accumulation. However, when the character moves to a scene outside the monsters’ line of sight, I removed the limitations and played the game at 1080p, 60Hz until completion without encountering any issues. So I think the cause of the issue may be due to memory (VRAM) not being released in time. Of course, this is just my guess, and the actual impact should be determined by the log files.
