 ## Disabling I/O hooks
-* If you specify the DLL via -exec option, I/O and game specific hooks are disabled.
-    * e.g., `spice64.exe -exec bm2dx.dll -modules modules`
+* If you specify the DLL via -exec option, most I/O hooks are **disabled*, as well as any game specific hooks.
+    * e.g., `spice64.exe -exec bm2dx.dll -modules modules` causes game to launch bm2dx but without I/O emulation or IIDX-specific hooks.
     * If you still need to enable things selectively, you can specify `-io` to enable all I/O hooks again, only enable partial I/O emulation using things like `-acio` `-icca` `-device` `-extdev` `-sciunit`, and the game specific hooks (e.g., `-iidx`, `-sdvx`).
     * There are also other options such as `-devicehookdisable` which may be needed.
