Game Modification Station / Fanaticism / Brushless conflict resolution
« on: July 02, 2011, 12:09:43 PM »
Making this thread so as to not clutter up dark's thread concerning his project (though I hope he'll participate here)

Since Assassin's Brushless Sketch patch and my Fanaticism patch both modify the code block responsible for checking Magitek / Fanatics Tower command changes, they don't work together.

I'm not sure I can make a Limited version that is compatible without using free-space (which I'm loathe to do), but I have a non-limited version that does seem compatible with his brushless patch.

An IPS for this is attached (apply after his brushless patch), as well as the asm to generate.

This version "turns on" the following "normally available" commands when in the fanatics tower / in magitek armor:
Runic, Lore, Sketch, Dance, Summon

It also turns on a slew of not-normally available commands like health, etc... as this isn't really a limited version...

Dark, since I'm really making this patch with you in mind so to speak, here are some choices:

I can trivially make it not allow Runic. This has no down side.

I can also turn off Dance... if you don't care if I always replace the first item with Magitek / Magic no matter what is there (only really is a negative for Gogo as this makes him unable to Mimic) and always do nothing to the 4th slot (again only really a "negative" for Gogo as everyone else should have Item there anyway)

Or I can try and find some empty space and potentially break other patches you are using, and you'll probably have to wait longer for a resolution :)

Submissions / FF6Patch - Menu Blitz
« on: June 30, 2011, 08:47:59 AM »
This patch makes Blitz use a menu in a manner more or identical to Mog's Dance command, rather than using Street Fighter combo button selection. This impacts both the Blitz command in battle, and the non-battle Blitz skills menu.

The non-battle menu was simple changed to show the name of the Blitz rather than the button combination for that ability.

The battle menu was created "from scratch" though I still use the same "draw" routines the other menus use. It displays in a manner similar to Dance, and does maintain cursor memory in the same way (if turned on).

Because Blitz now uses a menu, the Blitz abilities listed have an associated targeting byte that indicate whether or not its an attack or healing ability; it shows an "attack all" cursor for the attack Blitzes, and a "self only" cursor for the two healing Blitzes.
This in no way alters the targeting of the abilities when the Blitzes when used; all single target attacks still hit a random enemy, etc. This patch could be extended to do that, but I felt that making them targetable was little overpowered given that Blitz has no cost.

The rar includes two screen shots that demonstrate how this looks.

I've done a play-through with this, and the only negative note I can make about this patch is that the text of the Vargas encounter at the beginning of the game is "misleading" if one somehow fails to Blitz him before he starts going on about "PUSH LEFT, RIGHT, LEFT"...

However, given that Blitz functions off a menu and are therefore trivial to activate, and that Vargas encounter instructions are totally unnecessary and don't even show up unless one waits a long time to Blitz... unless one is trying to "test" this patch, one will undoubtedly Blitz him before this happens and not / hardly notice it.

Submissions / FF6 Patch - Tower of Fanatics / Magitek
« on: June 21, 2011, 02:22:52 PM »
Nomally only MagiTek, Magic, Item, and Mimic are available during Magitek events / the Tower of Fanatics.

This patch makes all but Steal, Capture, SwdTech, Throw, Tools, and Blitz available during these events.

There is a more limited version included as well which makes only MagiTek, Magic, Item, Mimic, as well as
Lore, Sketch, and Summon available. (I.e. Just adding availability to the last 3).

Game Modification Station / Blitz Battle Menu Tweak
« on: June 20, 2011, 09:46:03 AM »
Hmm so I'm working on making blitz use a menu, rather than do "street fighter" button matching because as awesome as the original functionality is/was... it is some what obnoxious to use at times compared to other abilities...

All of this work is heavily based on, and not possible without the documentation provided on this site credit of Imzogelmo, assassin, Lenophis, and Novalia Spirit. Anywhere I say Assassin here, I really mean any of these four individuals but since I no way to break that down, and for brevity's sake... I'll just say Assassin. Also since I'm looking at his C2 doc on occasion as well... its safer ^_^

So I got it to the point that selecting blitz brings up a menu with 8 entries, which correctly correspond to Pummel through Bum Rush in two columns in a normal english reading order (left->right, next line below). Selecting an ability causes that ability to occur normal, etc.

However I have two problems:

The first problem that I have is that the method I've chosen for loading the available Blitz commands is modeled after Magitek, so it loads a static list of the 8 entries... meaning if you only know Pummel, it still allows you to try and use... say Fire Dance, and then when he tries to execute it, "Incorrect Blitz Command" happens as if you messed up the button entries.

I'm not too worried about this, because I've not really tried to fix this yet but seems like I can use the old Blitz code as a guide there, as this is minor compared to my second issue... though it should be noted that in general I modeled all the crap I changed the Blitz code to is based off Magitek / Dance.

The second problem that I have is that the text for the entries isn't being loaded correctly, and isn't in the right location (though the finger selector is). See the attached screen shot [edit: removed]...

Anyone have any thoughts on this?

Here is the ASM for the changes I made for this (along with my insane and possibly wrong/confusing notes... as well as some original comments from Assassain's C2 doc on Magitek):

Game Modification Station / Throw-a-rang tweak
« on: June 06, 2011, 01:03:01 PM »
Hi,

Been a long time since I've done anything in assembly, so wanted some idiot check some work of mine if anyone is willing...

I wanted to start hacking up some bits of FF6 that I found annoying, but no existing patch to rectify. Among those, I was looking to change throw so that it doesn't use up the thrown item, without impacting normal item usage. This seemed 'easy' so I wanted to start with this.

Thanks to the awesome work by assassin17 and others, I can find this block of code:
Code: [Select]
Throw

C2/188D: A9 02        LDA #$02
C2/188F: 85 BD        STA $BD     (Increment damage by 100%)
C2/1891: A9 10        LDA #$10
C2/1893: 14 B3        TRB $B3     (Clear ignore increment on ignore defense)
C2/1895: 80 07        BRA $189E


Item

C2/1897: 9C 14 34     STZ $3414    (Set ignore damage modification)
C2/189A: A9 80        LDA #$80
C2/189C: 14 B3        TRB $B3      (Set Ignore Clear)
C2/189E: BB           TYX
C2/189F: A9 01        LDA #$01
C2/18A1: 8D 12 34     STA $3412
C2/18A4: AD 7D 3A     LDA $3A7D
C2/18A7: 20 C1 19     JSR $19C1
C2/18AA: A9 10        LDA #$10
C2/18AC: 14 B1        TRB $B1      (clear "don't deplete from Item inventory" flag)
C2/18AE: D0 05        BNE $18B5    (branch if it was set)
C2/18B0: A9 FF        LDA #$FF
C2/18B2: 9D F4 32     STA $32F4,X  (null item index to add to inventory.  this means
                                    the item will stay deducted from your inventory.)
C2/18B5: BD 18 30     LDA $3018,X

It seems to me that since both 1895 (a branch) and 189E (the branch target) are preceded by the same command ( TRB $B3 ) that I can save two bytes in the "Throw" block by retargetting the branch at 1895. That leaves me two bytes at 1893 that I can use to do something else as long as I don't alter the accumulator. Since 18AC and 18AE skip the item decrement code if the $B1 flag is set appropriately, I can use those saved two bytes from the branch retarget to set the $B1 flag ( TSB $B1 ) at 1893.... leaving me with the following in xkas assembly which essentially just replaces the last two lines in the "Throw" block:

Code: [Select]
hirom 
header 

org $C21893
TSB $B1     ; set the don't deplete from inventory flag
BRA $#05  ; branch to 189C

I seem to get the desired result, both with and without the "For what Ail's ya" patch applied.

However, I'm wondering if I should move 1891 down to 1893 and vice versa such that TSB proceeds the LDA, but I'm not sure it matters as long as the accumulator has $10 loaded when the branch executes.
