Well I found the lobby events file in data2.cpk and a constant variable called "ANNOUNCE_UNLOCK_TOK" - using genser to turn it into an xml file - and according to animegamemods, TOK is the character ID for the Supreme Kai of Time. Also the file contains event trigger variables and conditions for events triggering using system variable flags, global variable flags, and constant variable flags. And then, in the event ID variables, it contains data that points to which file has the script for these events and then provides argument variables that refer to constant variable values, global variable values, and other IDs that are a part of that event. I'll have to take a crack at looking at all this and figuring out how I can try to trick the game into triggering the character unlock for Chronoa offline. I don't have any proof that this will work or get me anywhere, but the fact "ANNOUNCE_UNLOCK_TOK" is a name of one of the constant variables and this file appears to control the conditions in which event flags are triggered appears to be a lead.
