New thing to figure out: How to change music in towns/shops/battles
I had thought about that before but since most of us play on speedup it wouldn't matter right? :wink:
it matters :)
Meteorstrike saw this and pitched in:
Quote:Here's some info in changing the musicPut a breakpoint on execute at $BF5F. When you enter a new area, this is the code that will determine which music to load.
You will notice something like:
LDA $47
CMP #7F
BNE $BF69
LDA #20
BNE BF7B
…
The value of $47 is the "area type" and is calculated elsewhere. I wouldn't mess with it if I was you because this "area type" is used for a lot of other things. It's best to change the music here. It's basically something like:
If area type == 0x7F ( Villages ) use music 0x20. Else, look at the value of $49 and use that as an index into $BF7F to determine the music to load. If this is the world map though (X == 0 ) then check $6010 to see if we should load the "fancy" music. I'll let you explore the rest.
Use these game genie codes for testing:
TZNUNYYZ = World map has kick-ass boss music
IZNUNYYZ = World map has some other kick-ass boss music
The world map (index 0 of $BF7F) is at 0x03BF8F and has value of 0x27
I'm still lurking but I'm not done with the DoaE2 stuff. I've barely touched it since that one week where I made some kick-ass boss music progress. Real-life work caught up and I'm still in crunch mode until Dec. 23…
MidKnight, I need a favor if you don't mind. As we know, using Ji Mian and Ce Mian is always successful after we use but there's a chance that it would either fail immediately the next turn or may last for several turns, so what I'm asking is that is it possible for you to somehow figure out the percentage of the effectiveness or the fail every time after we used them ?
DoaE gave birth to Huo Hu.
the problem with guaranteeing it, however, would make it pretty abusable. But I understand there has to be some kind of % that is determined @ the end of every turn. Maybe #/255 or something.
Well the first thing to find out would be, "how do I know if Ji Main/Ce Mian is turned on or not?" After some testing I found the locations:
Enemy statuses:
$6222 = #$00 <– Cheng Nei, Ji Rou/Guard, Wuo Jian, or Shui Jian on?
$6224 = #$00 <– Ce Mian on?
$6226 = #$00 <– Ji Main on?
$6228 = #$00 <– Yi Xin on?
$622A = #$00 <– Li Jian on?
$622C = #$00 <– Qi Shou on?
$622E = #$00 <– Bei Ji
Ally statuses (basically one after each enemy status):
$6223 = #$00 <– Cheng Nei, Ji Rou/Guard, Wuo Jian, or Shui Jian on?
$6225 = #$00 <– Ce Mian on?
$6227 = #$00 <– Ji Mian on?
$6229 = #$00 <– Yi Xin on?
$622B = #$00 <– Li Jian on?
$622D = #$00 <– Qi Shou on?
$622F = #$00 <– Bei Ji
The value stored decides which allies/enemies it is turned on for. For the case of $6222 and $6223 the value determines which tactic is in use (Cheng Nei, Ji Rou, Wuo Jian, or Shui Jian).
Another interesting piece is that if the enemy successfully uses Jie Ce/Negate it zeroes out all the ally statuses and if an ally successfully uses Jie Ce/Negate it zeroes out all the enemy statuses.
So now just need to chase down when the Ji Main/Ce Mian flag gets switched off and what is triggering it.
First let me put these memory locations in the guide as these will be important for other enhancements (like if we were to make the A.I. smarter so the enemy doesn't spam Wuo Jian or Qi Shou).

So at $A2B3 this time it decided that Ji Mian should expire because A was >= 05.
So with the above info we should know how to:
a) Change it so that Ji Mian stays on forever (until Jie Ce/negate)
or
b) Change it so that Ji Mian expires after 1 turn always
or
c) Change it so that Ji Mian expires after a fixed number of turns.
To change the randomness of it might be the hardest job as it seems to be calling pre-stored randomizer type code that's probably used elsewhere too.
To do any of these we just have to influence the decision made here:
$A2B1:C9 05 CMP #$05 A:05 X:B0 Y:00 P:nvUbdIzc
$A2B3:90 27 BCC $A2DC A:05 X:B0 Y:00 P:nvUbdIZC
What exactly were you looking to do Zhuge?
1. question, did you ever figure out if Cheng Nei even does anything, its supposed to raise Defense but…
2. How much does Qi Shou raise agility and does it affect multi-attacks? It seems to not really do anything at the present time.
Something that might be cool… What if Ji Main/Ce Mian was still random but had a set limit of 5 turns. If it lasts 5 turns it costs the whole T.P. but if it expires before that you are only charged a portion of the T.P. Example:
Ji Main costs 7 TP in the original game. What if we made it so that:
Lasts 1 turn: 2 TP
Lasts 2 turns: 4 TP
Lasts 3 turns: 6 TP
Lasts 4 turns: 8 TP
Lasts 5 turns: 10 TP
Ce Mian costs 17 TP in the original game. So it could be…
Lasts 1 turn: 4 TP
Lasts 2 turns: 8 TP
Lasts 3 turns: 12 TP
Lasts 4 turns: 16 TP
Lasts 5 turns: 20 TP
That way you don't lose a ton of TP when it only lasts 1 turn.
Quote:1. question, did you ever figure out if Cheng Nei even does anything, its supposed to raise Defense but…2. How much does Qi Shou raise agility and does it affect multi-attacks? It seems to not really do anything at the present time.
Not yet but I am curious about that also. Will find out more in a bit. Right now I'm guessing that Qi Shou doesn't do anything with the actual agility stat but just makes it more likely you'll go first. When you actually see the code you see just how worthless some of these tactics are (like Tui Lu).
EDIT: I think I was right about Qi Shou. It seems to be read when the battle turn starts and we use it to help determine who should go first. However, Qi Shou does nothing to a general's actually agility stat so it has no effect on agility based attacks. How to address this? Twist ludmeister's arm to see if he can factor if Qi Shou is on in his formulas? Whether Qi Shou is on or off is stored here:
$622C = Enemy Qi Shou status
$622D = Ally Qi Shou status
And the value represents which allies/enemies have Qi Shou turned on. For example 01 = only the first ally, 1F = all allies.
So perhaps lud can adjust his formula to say if Qi Shou is on, make it more likely that multiple hits will happen. If he did that it would make Qi Shou a pretty nice tactic.
Indeed it would, twere my thoughts exactly on tweaking it and my thoughts on changing Cheng Nei were to replace it make it like using a power pill and score an auto-crit hit on one officer.
An idea I had before for Cheng Nei was to combine Cheng Nei, Wuo Jian, and Shui Jian into 1 tactic called "Protect" or something which is half as strong as Ji Rou/Guard. That would free up 2 more tactic slots to do whatever with.
EDIT: Wow…after some more digging…it doesn't look like Cheng Nei is doing anything! Compare:
Ji Rou / Guard:
00:98CA:BD 22 62 LDA $6222,X @ $6223 = #$01
00:98CD:4A LSR
00:98CE:90 06 BCC $98D6

00:98D6:A4 78 LDY $0078 = #$07

Cheng Nei *and* Normal Attacks:
00:98CA:BD 22 62 LDA $6222,X @ $6223 = #$08 (00 for normal attacks)
00:98CD:4A LSR
00:98CE:90 06 BCC $98D6
— skip —
00:98D6:A4 78 LDY $0078 = #$07
00:98D8:A5 7A LDA $007A = #$01
00:98DA:49 01 EOR #$01
00:98DC:AA TAX
Then it never pulls that value again. It throws it away… So unless I'm missing something it looks like Cheng Nei is 100% worthless. I'll ask Meteorstrike if he can verify if this is true or if I am just missing something.
Cheng Nei code when it is first run:
