Not making guest to leave,but to make a playable character to leave.Is it possible and how?
It's possible with my Event Instruction Upgrade (http://ffhacktics.com/wiki/Event_Instruction_Upgrade) hack, but that's going to require you to do some Event Editing, which for unknown reasons, most people are afraid to attempt.
If you're still interested, you can check out Elric's tutorial which I think is this? http://ffhacktics.com/smf/index.php?topic=8229.0
After learning your way around event instructions, I can teach you to do what you want.
Actually i've already give it a start last year,but then was too busy to continue until now.I'll dig deeper to learn more about event editing.
By the way,i've remembered seen somewhere(can't remember which topic) that there is a way to make character join sliently like those cadets in chapter 1.how?
nevermind about join sliently i think i've found it.
by the way is EventInstructionUpgrade.xml an ASMhack which need to be patched with FFTorgAsm before using?
Yes, otherwise you can compile the new instructions, but they'll just break the event.
