Taisei is an open clone of the Tōhō Project series. Tōhō is a one-man project of shoot-em-up games set in an isolated world full of Japanese folklore.

You can find the source tarballs at the Releases section on Github. Do not grab Github's auto-generated source archives, those do not contain the required submodules. This only applies for versions v1.3 and above.
If you cloned Taisei from git, make sure the submodules are initialized:
git submodule init git submodule update
This step needs to be done just once, and can be skipped if you specified the
--recurse-submodules option when cloning.
Important: You should also run
git submodule update whenever you pull in
new code, checkout another branch, etc. The
scripts can do that for you automatically.
To build and install Taisei on *nix, just follow these steps:
cd /path/to/taisei/source mkdir build cd build meson --prefix=$yourprefix .. ninja ninja install
This will install game data to
$prefix/share/taisei/ and build this
path statically into the executable. This might be a package
maintainer’s choice. Alternatively you may want to add
-Dinstall_relative=true to get a relative structure like
install_relative is always set when building for Windows.
The OpenGL ES 3.0 backend is not built by default. To enable it, do:
meson configure -Dr_gles30=true -Dshader_transpiler=true
See here for information on how to activate it. Alternatively, do this to make GLES 3.0 the default backend:
meson configure -Dr_default=gles30
The OpenGL ES 2.0 backend can be enabled similarly, using
gles20 instead of
gles30. However, it requires a few extensions to function correctly, most
Taisei stores all data in a platform-specific directory:
- On Windows, this will probably be
- On macOS, it's
- On Linux, *BSD, and most other Unix-like systems, it's
This is referred to as the Storage Directory. You can set the environment
TAISEI_STORAGE_PATH to override this behaviour.
Taisei uses SDL2's unified GameController API. This allows us to correctly support any device that SDL recognizes by default, while treating all of them the same way. This also means that if your device is not supported by SDL, you will not be able to use it unless you provide a custom mapping. If your controller is listed in the settings menu, then you're fine. If not, read on.
An example mapping string looks like this:
03000000ba2200002010000001010000,Jess Technology USB Game Controller,a:b2,b:b1,back:b8,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,dpup:h0.1,guide:,leftshoulder:b4,lefttrigger:b6,leftx:a0,lefty:a1,rightshoulder:b5,righttrigger:b7,rightx:a3,righty:a2,start:b9,x:b3,y:b0,
There are a few ways to generate a custom mapping:
- You can use the controllermap utility, which comes with SDL source code.
- If you use Steam, you can configure your controller there. Then you can add
Taisei as a non-Steam game; run it from Steam and everything should just
work™. In case you don't want to do that, find
config/config.vdfin your Steam installation directory, and look for the
SDL_GamepadBindvariable. It contains a list of SDL mappings separated by line breaks.
- You can also try the SDL2 Gamepad Tool by General Arcade. This program is free to use, but not open source.
- Finally, you can try to write a mapping by hand. You will probably have to refer to the SDL documentation. See gamecontrollerdb.txt for some more examples.
Once you have your mapping, there are two ways to make Taisei use it:
- Create a file named
gamecontrollerdb.txtwhere your config, replays and screenshots are, and put each mapping on a new line.
- Put your mappings in the environment variable
SDL_GAMECONTROLLERCONFIG, also separated by line breaks. Other games that use the GameController API will also pick them up.
Also note that we currently only handle input from analog axes and digital buttons. Hats, analog buttons, and anything more exotic will not work, unless remapped.
If your sound becomes glitchy, and you encounter lot of console messages like:
ALSA lib pcm.c:7234:(snd_pcm_recover) underrun occurred
it seems like you possibly have broken ALSA configuration. This may be fixed by
playing with parameter values of
pcm.dmixer.slave option group in
/etc/asound.conf or wherever you have your ALSA configuration.
rate may give
you the first approach to what to do.
