About Taisei Project

Taisei (泰西, lit. Occident) is a free and open-source fangame of the Tōhō series, written in C using SDL2 and OpenGL.

What's new in 1.4.2

This is a stable maintenance release. It features some bugfixes, optimizations, and other improvements backported from the v1.5 development tree.

  • Reworked gamepad input handling and configuration:
  • The free/restricted axis distinction is gone; the joystick always operates in "free" mode.
  • Added direction snapping functionality to help aid exact movement in cardinal and/or diagonal directions. The snapping angle can be adjusted from 0% (disabled) to 100% (similar to the old "restricted" mode). The snapping angle can also be biased towards cardinals or diagonals.
  • When the maximum zone is less than or equals dead zone, moving the character will always move at maximum speed (as in the old "restricted" mode).
  • Most of these settings are now visualized in the options menu and can be tested there.
  • Changed the default Spell Card (Bomb) and Power Surage gamepad bindings to Left Trigger and Right Trigger respectively.
  • If autorestart is enabled for spell practice, it will now try to load a quicksave if one exists.
  • Added a "load quicksave" option to the pause menu in practice modes.
  • Cutscenes that have been seen before can now be completely skipped.
  • Added an option to reset the config to last saved values.
  • Reduced some sprite batching CPU overhead.
  • Optimized rendering of scenes with many lasers.
  • Optimized loading of webp files.
  • Optimized various math routines.
  • Improved performance of some shaders.
  • Due to bad OpenGL drivers, macOS releases now use ANGLE for rendering by default. This fixes serious performance issues on some Apple systems.
  • Worked around broken rendering in WebGL on Apple systems with certain versions of ANGLE (see #386). The ANGLE bug has been fixed upstream, but certain systems are known to still be affected, such as iOS 18.
  • Fixed crashes related to opening the pause menu.
  • Fixed the cutscene text spontaneously disappearing on some systems.
  • Fixed laser rendering errors during screen-shake effects.
  • Fixed some minor general rendering errors.
  • Fixed rendering errors specific to WebGL and ANGLE on Windows.
  • Fixed ongoing asynchronous tasks (e.g. screenshot encoding) sometimes failing to finish when exiting the game.
  • Fixed some erroneous build warnings when building with Clang 18+.
  • Fixed pseudo-random lookup order when a resource exists in multiple locations. This allows files placed in sub-packages to override those from 00-taisei.zip reliably.
  • Removed the defunct gles20 renderer backend. …
