I might be misunderstanding you or maybe I just wasn't clear in my explanation. When I was referring to the Ty the Tasmanian Tiger series and the 01 value, that actually represents the game having a frame rate lock of 30fps. Changing that value to 00 turns off the frame rate lock so it runs at 60fps. There might be a way to get the game to run lower than 30fps, but setting the value to 02 or higher won't change that in this case. In Metroid Prime 2 multiplayer, there is also a value that is used to turn on a frame rate lock. In this case, the value is 80 and like Ty, it needs to be changed to 00 to be turned off.
As for your question about cutscenes, I really don't have a good idea how to go about that. You could try taking a look at the .map file to see the various functions, although I don't really know how to do anything with the functions listed. You can see, for example, that at address 80070978 there is update__15CinematicPlayerFv, which is connected to plugPikiColin.a cinePlayer.cpp. I don't really know that this would be in the same section that mentions the speed of the cutscenes. I don't even know that it's referring to the cutscenes instead of the FMVs, although I am guessing it is while moviePlayer.cpp refers to FMVs.
