Installing only SilentPatch to test changing the frame cap (which does work), I got a mod updater window with... a ThirteenAG link? That's somewhat surprising but it makes sense. I've heard of this Ultimate ASI Loader thing before, and I guess I just didn't know it was a ThirteenAG thing despite having used ThirteenAG's widescreen fixes for other games. I'm guessing ThirteenAG's widescreen fix and SilentPatch both use Ultimate ASI Loader under the hood and that's why it's okay for the latter to overwrite the former's dinput8.dll file per those instructions.
