Config

Here we can explain slow mode, 16/32 bit, getting a good MIDI library, and so on.

16/32 bit: If you have a slow computer/poor graphics card, you want to use 16 bit. A slow of over 2% is not so good.

In the game options screen, there is a "Slow Mode" (Shotslow?) option. It causes the game to slow down when there are lots of bullets on the screen. This invalidates replays and high scores.

Embodiment of Scarlet Devil

Disable vertex buffers

Disable fog

Only use 16 bit textures

Disable Gouraud shading

Don't color composite all textures (eh... no idea. テクスチャに一切のカラー合成をしない)

Start in reference rasterizer mode

Clear backbuffer every time (every frame, I guess)

(again, no idea. "Only display the bare minimum?" 必要最低限のものを残して表示しない)

Turn off depth test

Force 60 fps (I need to have this one checked in order to save replays.)

Don't use DirectInput

Window style: Fullscreen / Window

Draw interval: Every frame (normal) / 1/2 / 1/3

Screen mode: 32bits / 16bits

Pad left/right play (size of dead zone on analog stick, maybe?)

Pad up/down play

Confirm pad direction key (press direction key on pad and it displays here. For
testing the settings above, I guess.)

Perfect Cherry Blossom

Left column

Disable vertex buffers

Disable fog

Force 16 bit textures

Don't use DirectInput for pad input

Read BGM into memory

Window style: Fullscreen (recommended) / Window

Effect quality: Worst / Medium / Beautiful (recommended)

Right column

Don't color composite all textures

Turn off depth test

Start in reference rasterizer mode

Draw screen surroundings every time (redraw the area outside of the playing field each frame, I guess)

Don't take VSYNC (Don't wait for VSYNC?)

Screen mode: 32bits (recommended) / 16bits

Draw interval: Every frame (normal) / 1/2 / 1/3

Bottom area

Pad left/right play

Pad up/down play

Confirm pad direction key (this one doesn't seem to work for me.)

Imperishable Night

A well translated version of the configuration can be found here

Left column

Disable vertex buffers

Disable fog (not recommended)

Force 16 bit textures

Don't use DirectInput for pad input

Read BGM into memory

Window style: Fullscreen (recommended) / Window

Effect quality: Worst / Medium / Beautiful (recommended)

Right column

Don't color composite textures (forbidden)

Turn off depth test (not recommended)

Start in reference rasterizer mode (forbidden)

Draw screen surroundings every time

Don't take VSYNC (not recommended)

Screen mode: 32bits (recommended) / 16bits

Draw interval: Every frame (normal) / 1/2 / 1/3

Bottom area

Pad left/right play

Pad up/down play

Confirm pad direction key (this one doesn't seem to work either.)

Phantasmagoria of Flower View Demo Version

There's a translated config.exe here (in English). (The other .exe are mistranslated.)

Subterranean Animism

Top

Do not use DirectInput

Enable slow shot

Left side, first frame - Window mode

Full screen (640x480)

Window (640x480)

Window (960x720)

Window (1280x960)

Ask every time you start the game

Left side, second frame - Screen mode

32 bits (Recommended)

16 bits

Left side, third frame - Drawing interval

Every frame (Recommended)

1/2 frames

1/3 frames

Left side, fourth frame - Gamepad

If the input is not sensitive enough, decrease the slider. If the input is too sensitive, increase the slider. (Default: 600)

Right side, frame - Input latency

Stable (This usually does not work well)

Normal (Uses less CPU power)

Auto (Automatically detects the fastest response) *Recommended

Fast (Use if Auto does not work properly)

Right side, notes

With the input latency setting, you can fine-tune the input response. "Stable" and "Normal" are the original responses. "Auto" will give you the fastest input if you're using the machine's full performance. "Fast" is similar to "Auto", although the screen may have some trouble. *The draw distance "Every frame" is not valid outside*

Right side, button

Reset to defaults

Bottom

Exit without saving

Save and exit

There's a couple things I couldn't figure out entirely what they were trying to say so I used a literal translation. Most everything is straightforward, though.
