Oh. Wouldn't it be possible to give users more fine tuning options available to get faster speeds out of games that seemingly don't require those specific functions? Sort of like the extensive Speedhacks available in PCSX2?
Dolphin's developers are really not keen on that sort of thing. Neobrain in particular seems to detest hacks and workarounds. They always favor accuracy over performance, and any features like the kind of hacked speedups you mentioned that have been included are eventually removed.
