FAQ

Is the patch compatible with other mods or patches?

The patch has been only tested against thcrap.

• Feel free to report any issues that occur.
• Other mods or patches might require testing.

Does the patch support games prior to Touhou 10?

All games prior to Touhou 10 aren't supported due to D3D8.

• To fix this, install d3d8to9 to promote D3D9.
• Any games that use D3D8 will now be compatible.

Why not use vpatch for "borderless fullscreen"?

Though vpatch allows one to run the games at any resolution.

• It requires you to intervene & configure it.
• You also somewhat compromise on fullscreen.
