Looks correct, and I found that command in the startup on the load screen, but I changed it so that Crono should NOT be locked, yet lo and behold, he still was. Maybe there was a second command during the opening scene in his house that was there to make SURE he was locked.
You're right, there's a second command. In room 10F Special Purpose Area (Event 169), at offset 019E. Bitmath 7F01DF, 80, set.
The Special Purpose Area is used for events between events. Usually, a textbox over a black background. This is where the "Crono! Crono! Wake up, Crono!" intro is located.
