Boshyst

IWBTB mod with hacks and tools to help speedrunning and creating TAS

Screenshots

Cold start (mod menu)

Put Boshyst DLL and DLL Injector into the game folder.
Launch the game, open command prompt in the game folder and type:

Menu should be opened (toggled by Insert as a default bind).

Cold start (BTAS) (experimental)

Just also put BTAS launcher into the game folder and launch the game via it.
Open the config to see binds.
Known problems:

• Save files forgetting after loading a state (breaks in-game save logic, also some visual stuff which game thinks is locked) (can be fixed: see
  tas_save_slot_fix
  in config)
• RNG seed desyncs (also might be caused by changing visual settings)
• Hitbox desyncs (TODO: research why DirBlur x3.fx affects that)
• Some input problems (you can shoot right after loading a state even if you shot right before saving; pressing C right after load won't work => desyncs)
• May crash when loading a state (seems to be memory corruption, also happens without BTAS, would be really difficult to fix) (seems to be using software render with
  MESA
  +
  WineD3D
  reduces ammount of crashes)

Building and running

For testing, just build the DLL using Visual Studio and inject it into the game process (

config will be created is in the game dir).
For hourglass (Windows XP compatible), build the DLL using Visual Studio 2010 (manually create a project and add all the C++ files, configure includes), put it into the game folder (with config file, also set

tas_mode

to 1 in config), replace

wintasee.dll

with modified version to automatically inject the mod when launching the game through the hourglass. Allow normal thread creation.
Building helper scripts (use MinGW32 for compatibility):

Configuring

See

in the game folder

Recording video

For hourglass, use special modified hourglass r90 version.
Set

to

1

.
FFmpeg is required to be in

PATH

variable.

• FFmpeg for modern Windows
• FFmpeg for 32-bit Windows 7 (Use GPL builds)
• FFmpeg for Windows XP

Automatic start/end of the recording can be configured with

,

render_count

/

render_end

(not recommended).
It's recommended to set start/count vars to 0 and use start_cap and end_cap scripts.
Not using direct render <=> front buffer capturing.
Using direct render <=> back buffer capturing.
Capture starts from the frame you will see, and ends with the frame you currently see.
Warning: game window should not be resized while recording.

Recording audio

Before replaying TAS, set

and

tas_audio_main_thread

. Then replay TAS without using fast forward. Then stop audio recording and close the game.
Run

amerge.bat

script created in the game folder to join all sounds in a single output (it requires FFmpeg).
NOTE: Fading is not supported yet (kinda used in credits only).
