Asking for Tools & Methods about changing the sound effect in the decomp files.

WiserVisor, May 6: You are correct in saying that the sound effects are based on certain soundfonts. While midis are used to create the files necessary for the ROM to read the sound data for music, for a sound effect, we don't have to create a midi. If you want to add...

How can I make battle animations start when the text starts printing, not after?

SBird, Mar 19: The actual order of how events are executed is defined by move effect itself, so it is not trivial to change. Also: The attackstring is printed even if a move misses, the animation is only played if it actually hits, so there's also that. ~SBird
