I feel dumb for asking, but I just can't figure out what the frame search function is used for. Maybe I'm not using it correctly. Could someone elaborate what it is, what it can be used for. Maybe if I can understand this function it'll make creating a TAS easier for me. Who knows? =) Thanks in advance.

See, I dont entirely understand that. The way I've been doing it is just using a save state for these things. I don't see how this function is any different than another save state that speeds the game back up to full speed after i press it, which is inconvenient when TAS'ing =(

Would an example help? I hope so, here is an example: Let's say your character is walking right towards a door, and you want to be sure that you press up on the first possible frame that will open the door. For the sake of argument, holding up while walking right would not open the door, so it requires frame precision to open it as soon as possible. With frame search: 1. Pause and frame advance right for 1 frame as you're walking toward the door. (optional) 2. Hold up, and keep pressing the frame search button until the first time you see the door open. 3. If you accidentally press frame search too many times, use the frame search rewind button to undo the extra presses. (optional) 4. Finally, press the frame search finish button, and save the state. You now have a state that's guaranteed to open the door on the first possible frame, saved at the earliest possible time after opening the door. Notice that there is no need to load a state, frame advance some frames, and switch buttons for each frame you test this way. That all gets reduced to a single press of the frame search key per frame being tested, which does that stuff automatically and shows the result. This works great for things like menus, jumping on the first possible frame, hitting the attack button on the frame that gets the best luck, etc. It's trickier when the action is more complicated than holding a button (you can't use it to spin dash in a Sonic game, for instance).

Alright, thanks nitsuja, I think I get it now. Spose it beats doing it the way i've been doing it and counting it out several times for every spot I need to test.
