Linux Test 8

on GitHub

This is the eighth test release of the native Linux version of B2recomp. It is a pre-release: the Windows version is v0.3.0. As always, this download contains no game files: the game is built on your PC from your own dump.

Opening an issue on GitHub: it must be written in English and have the report attached (b2recomp-report.tar.gz: press Report... in the launcher, or run sh scripts/report.sh). An issue opened without both will be closed promptly.

New since Linux Test 7

The fix of Windows v0.3.0:

• A rare crash when a cutscene starts. A cutscene picks its characters once when it starts and keeps using them. If the game removed one of them while the cutscene was still playing, the cutscene kept using the removed character and the game closed. It was seen once, at 120 fps, in the cutscene after Verse 10 "Run from the Enemy!" (Loki's chase). Now a cutscene lets go of a character the game removes and takes the one that replaces it. This works at every frame rate; normal play is unchanged.

The README also describes how Windows players update (v0.2.10); nothing else changes for Linux.

Updating from an earlier Linux test release

Unzip B2recomp-linux-builder-63b51a9.zip over your old B2recomp folder and start B2recomp. It says that B2recomp was updated; press Build (a short rebuild, about two minutes), then Play. Your settings and saves stay.

New install

1. Unzip B2recomp-linux-builder-63b51a9.zip where you want to keep the game, for example ~/Games.
2. Open the folder and start B2recomp: double-click it, or in a terminal run sh ./B2recomp.
3. Choose your dump folder (one folder that holds exefs/ and romfs/ of Bayonetta 2, version 1.2), press Build (5 to 20 minutes, depending on your CPU), then Play.

You need 64-bit Linux from about 2022 or newer with a desktop (X11 or Wayland) and a Vulkan 1.3 driver (Mesa for AMD and Intel, or NVIDIA's own driver). START HERE.txt in the zip has the details.

Known limits of this test release

• The game times its frames with its own clock, not with your monitor's refresh as the Windows version does. You may see a slight judder now and then.
• The renderer finds out which textures the game changed by checksumming them (on Windows the system tracks this), which costs a little more CPU per frame.
• The v0.3.0 fix was tested on Windows; the Linux build compiles it, but it has not been tried on Linux yet.
• Tested on Arch-based systems (CachyOS) with an NVIDIA RTX 4060 laptop and an AMD RX 560, on KDE and Hyprland (Wayland). Other distributions should work, but are untested.

Reporting problems

Press Report... in the launcher, or run sh scripts/report.sh in the B2recomp folder. It makes b2recomp-report.tar.gz with the logs and your PC's details, and nothing of the game. Never attach game files.

Issues must be written in English and must have the report attached. An issue opened without both will be closed promptly.
