+# DirectX 8 to 9 wrapper
+Source: https://github.com/crosire/d3d8to9
+
+Includes:
+* d3d8.dll (compiled binary)
+* Source code for compiled binary
+
+# Why?
+Some Konami games are quite old and don't run well on modern versions of Windows (7 and newer):
+* Framerate is not locked to v-sync though v-sync is turned on
+* Random stuttering and slow-downs
+
+Games with these issues experienced thus far:
+* IIDX 9 to 13: Even with bemanitools various settings in place, these games would not run flawlessly on Windows 10: Random stuttering in menus and during songs causing them to drift off-sync though the framerate was supposed to be stable.
+
+# Install
+* Requires the D3D9 SDK: https://www.microsoft.com/en-us/download/confirmation.aspx?id=8109
+* Put the d3d8.dll next to your game executable.
+
+For example:
+* IIDX: Put d3d8.dll next to bm2dx.exe.
