Patch for keeping Shadow around?

Some Event Editing questions about Shadow. I've gone through the Event Dump looking for what it is that makes Shadow suddenly leave the party in the WoB areas he's in. Also, I've been looking into the code that kills him off if you leave him on the Floating Continent.

I don't want either of these things to happen anymore. I vaguely recall that there's a patch out there already that does this. Does anyone know of it?

Otherwise, I'm going to have to go through these bits of code and figure out what to NOP:

Code:

Shadow leaves commands
CB/9AAE: DE    Load CaseWord with the characters in the currently active party?
CB/9AAF: BE    If character $03 (SHADOW) is in the current CaseWord, call subroutine $CBA3B9

CB/A0EC: DE    Load CaseWord with the characters in the currently active party?
CB/A0ED: BE    If character $03 (SHADOW) is in the current CaseWord, call subroutine $CBA3B9

Questionably a Shadow leaves command
CB/BBB6: BE    If character $03 (SHADOW) is in the current CaseWord, call subroutine $CBBEC4

Shadow leaves, but may be necessary?
CB/BE79: BE    If character $03 (SHADOW) is in the current CaseWord, call subroutine $CBBEDD

Shadow leaves, branches to the text involved
CB/BFD0: BE    If character $03 (SHADOW) is in the current CaseWord, call subroutine $CBBFE9

That patch is one of Djibriel's, and is called the "Sticky Shadow patch"
You can find it here: http://www14.brinkster.com/assassin17/ho...atches.htm

Code:

Shadow leaves commands
CB/9AAE: DE    Load CaseWord with the characters in the currently active party?
CB/9AAF: BE    If character $03 (SHADOW) is in the current CaseWord, call subroutine $CBA3B9

This code removes shadow from the party when you're at the imperial camp and the doma map is loaded for the first time. Since you have the option of not recruiting shadow, the code is asking here "Did you recruit shadow? If you did, let's kick him out for Cyan's scene".

Code:

Shadow leaves commands
CB/A0EC: DE    Load CaseWord with the characters in the currently active party?
CB/A0ED: BE    If character $03 (SHADOW) is in the current CaseWord, call subroutine $CBA3B9

Same as above, this one kicks shadow out of the party for the scene where Doma is poisoned and Cyan goes ballistic.

Code:

Shadow leaves commands
Questionably a Shadow leaves command
CB/BBB6: BE    If character $03 (SHADOW) is in the current CaseWord, call subroutine $CBBEC4

This code is for just when you get off from the Phantom Train. The game checks if shadow is still in the party. If he is, then he is given some actions to perform (just before Owain and the wife boarding the train).

Code:

Shadow leaves commands
Shadow leaves, but may be necessary?
CB/BE79: BE    If character $03 (SHADOW) is in the current CaseWord, call subroutine $CBBEDD

This kicks shadow out of the party if he is present in it, just after the Phantom Train departs with Cyan's wife and child.

Code:

Shadow leaves commands
Shadow leaves, branches to the text involved
CB/BFD0: BE    If character $03 (SHADOW) is in the current CaseWord, call subroutine $CBBFE9

This last one kicks shadow out of the party when about to jump the waterfall for going to the veldt in sabin's scenario.

It seems to me that the code that randomizes shadow leaving from the party might be in the C2 bank.


Killing shadow on the floating continent is a consequence of the following code:

Code:

CA/579D: 4B    Display dialogue message $0872, wait for button press
               The airship's below.
               ^ (Jump!!)
               ^ (Wait!!)
CA/57A0: B6    Indexed branch based on prior dialogue selection [$CA48C1, $CA5EB3 (does nothing)]
CA/57A7: FE    Return

CA/57A8: 4B    Display dialogue message $0873, wait for button press
               ^ (Jump!!)
               ^ (Gotta wait for SHADOW…)
CA/57AB: B6    Indexed branch based on prior dialogue selection [$CA48C1, $CA5EB3(does nothing)]
CA/57B2: FE    Return

One way to do it may be to, instead of choosing to jump or to wait, NOP that part and instead make the code jump to CA/57BB, which is the code that is activated to bring shadow to the airship in the apocalypse scene

Code:

CA/57B3: C1    If ($1E80($1FE) [$1EBF, bit 6] is clear) or ($1E80($1FD) [$1EBF, bit 5] is clear), branch to $CA5EB3 (simply returns)

CA/57DD: CF        Turn vehicle/entity left
CA/57DE: FF        End queue

Shadow will leave at random times, if you spend too much time in the overworld before the train or falls he will leave the party. MY question is, do you have to go straight through the levels to keep him in the party?

Pretty certain that it's just a 1/16 chance that he leaves after every battle?

Unless you are in the Imperial Camp, or the Phantom Train, yes.
