A maintained and updated fork of Giuroll

Is a network rollback mod for 東方非想天則 / Touhou 12.3 Hisoutensoku, which aims to significantly improve the responsiveness of netplay, as well as introducing other rollback related improvements to replay mode.

Currently this is an early version, and might slightly increase instability, but will still significantly improve the netplay experience for almost all connections.

This repository also contains a stripped down version of the crate ilhook-rs, and a modified version of mininip, all rights remain with their respective authors.

Usage

For SWRSToys users

1. Navigate to your Hisoutensoku folder. You should see a subfolder called modules, and a file called SWRSToys.ini.
2. Drop the giuroll folder from this zip into modules.
3. Add the following line into your SWRSTOYS.ini

giuroll=modules/giuroll/giuroll.dll

4. Find the following line SWRSokuRoll=modules/SWRSokuRoll/SWRSokuRoll.dll.
5. Add a ; at the beginning of that line, making it

; SWRSokuRoll=modules/SWRSokuRoll/SWRSokuRoll.dll

For users without SWRSToys

See the Injector.

More information about the usage in game is available in the installation and usage.txt file inside the distributed zip

Replay Rewind

In replay mode pressing q will start rewinding the replay, and the A, S and D keys will affect the rewind speed.
Pressing z will pause the replay, allowing you to move frame by frame, backwards or forwards via the s and d keys respectively.

Usage with Tsk

When used with Giuroll, Tsk may record one battle multiple times. A workaround is provided for it:

To apply the workaround, SWRSAddr.ini of tsk should be edited: delete the original line which starts with SWRS_ADDR_PBATTLEMGR, or make it a comment by add a semicolon ; at the beginning of it, and then add the following line (also on the SWRSAddress section):

SWRS_ADDR_PBATTLEMGR = 0x0047579c

Building from source

The mod can be buit with cargo using the commands below.

rustup default nightly-2024-06-18
rustup component add rust-src --toolchain nightly-2024-06-18
cargo +nightly-2024-06-18 build --target i686-win7-windows-msvc -Z build-std --release

For debugging/developmental purposes, you may build with the --release flag omitted. This will open a console window and show further details while the game is running.

Common Problems

• Game doesn't load: check if the ini is valid according to the example ini provided in this repository, and is placed alongside the mod without any changes to it's name, and check for mod conflicts by disabling all other mods, and adding them back one by one.
• Failed to connect: either player is using an incompatible version of giuroll, or is not using it at all.
• Game desynced: I'm planning on adding a desync detector to make debugging desyncs easier, but since desyncs also occur with SokuRoll there is no guarantee they are caused solely by the rollback. If the desyncs are common, persists between game restarts, and are not appearing with Sokuroll, you can contact me about it.

You can send feedback about any issues through:

• GitHub issues, and/or
• @hagb_ in DMs or in a hisoutensoku server through Discord.
