Help! / Tools to improve hacking workflow?
« on: July 29, 2017, 10:04:11 AM »
I was thinking earlier about how much effort it would take to actually rewrite a set of routines, like reactions or forumulas.  Most of the difficulty even for an expert assembly programmer isn't in the programming itself, it's in managing all the information.  Everything you need to know is spread across hundreds of pages on the wiki, so first you need to manually copy and paste all those pages into a bunch of text files and come up with a system to document them and how they all fit together.  When you're done with that you must develop a build cycle so you can compile all these things, put them in the right place, and then get them into a disc image and test them.

This is suboptimal.  It's like trying to develop using build methods and techniques from the 1950s.  It's insane that we still do this in an era of free online source hosting with automated build tools.

Please note that I intend this thread as a discussion on the nature of these problems, and potential best practices and solutions.  I will present my opinion in replies to this.  I encourage everyone - hacker or not - to do the same.  My goal is to create a system where we can do the best hacking and programming with the least effort.  Do not be afraid to comment!

1. What is the ideal build cycle for an average assembly hacker?

2. What is the ideal build cycle for someone who wants to rewrite and optimize large portions of the game mechanics?

3. What is your current build cycle?

4. What tools exist to improve our build cycles?

5. What is the gap between the tools that exist and what would be ideal?

6. What tools, techniques, and protocols would lower the entrance barrier for assembly hacking?

7. What non-coding obstacles prevent you from setting up your ideal build environment?

8. Why did previous attempts at rewrites fail?

The Lounge / FFH image assets?

Where can I find the image assets from the previous incarnations of FFH?  Specifically the one where the area outside of posts replicated the FFT formation menu?

Help! / [Solved] Is the Heaven Thunder Back formula correct?
« on: December 05, 2016, 05:34:55 AM »*%28100-TarF%29*%28MA%2BY%29*MA/2%29#Hit.28Rdm.281.2CX.29.29

This gets some very weird results (72000 damage) when I feed it 70 faith for both parties and 5 MA.


Should be divided by 10,000 (or 100, twice), since the (100 - caster faith) and (100 - target faith) are actually percentages.

Help! / Does the weapon/item type in FFTPatcher determine forumula used?
« on: October 30, 2016, 01:40:24 AM »
If I change a specific knife to a sword-type in FFTPatcher would the formula it uses change as well?  Or are the formulas hardcoded to the specific item slots?

I'm pretty sure that only the equipped-in-body-slot is hardcoded (you can't turn a hat/helmet/ribbon into an armor/clothing/robe).

Help! / Wiki Attention Thread
« on: September 22, 2016, 03:18:17 PM »
I'm doing a bit of work since I have free time due to insomnia.  I'm adding links to every documented subroutine call (jal 0x????????) where it is called.

I do this by going to any formula or routine, ctrl + f jal, finding the address it jumps and links to, and then ctrl + f that address on the Routine Locations wiki page:

Generally a good idea to include on every subroutine what jal's to that page, but that's less important since you can use the Special Page "What Links Here" on the left sidebar under the tools menu to find the same information.

If you see anything that needs attention in the wiki make a post.

Question for asm hackers and wiki admins - why does the Return Locations section in those subroutines that are jal'd to contain the start of that routine as the address listed, instead of the address to which it would return after that routine?
The above page jumps and links to the below page 3 times:

Data Nullifying displays the addresses to which the jal subroutine calls in Current Action Data Nulling return.  Other wiki pages instead display the first address of the routine from which they are called, and not the addresses to which they return on completion.  Which should I use?

Something else, I've found several duplicate pages, with different titles and different comments on the disassembly.  I assume that these are parameterized, but shouldn't these duplicate pages acknowledge one another?

Help! / Need formulas or spreadsheets to calculate stat gains and damage
« on: September 06, 2016, 08:02:59 PM »
I saw them somewhere, but I don't recall where.

I need something that will calculate stats at level 1, 99, and somewhere in between for given raw stats and class growths and multipliers.  If I can then select an ability or a formula and the x/y values for it and have the damage at various levels that would be cool too.

statBonus at any given level = [currentRawStat / (Growth + Level)]

I know there's some math function - probably related to either sequences or series - that deals with this sort of thing, but I can't remember it.  I could easily write a loop to figure this out, or even a recursive function... if only I had paid attention in discrete math 2!


Screw it, I can make a command line program to do the calculations for me.

RAM -> File
-0x67000 -> WLDCORE.bin
-0x67000 -> Battle.bin
-0xE0000 -> World.bin
-0xF800 -> SCUS

Help! / How are exit tiles chosen in the Deep Dungeon?
« on: September 06, 2016, 04:57:47 AM »
The png maps of the Deep Dungeon by jekoln at GameFAQs indicate that each map has 1 exit tile out of 5 possible tiles.  Is this a table, and has anyone located it?  Also what does the event scripting of the DD differ from other maps?

Bugs and Suggestions / Possible to change the CSS for code tags?
« on: July 24, 2016, 12:47:05 AM »
If possible, I'd like the code tag to not expand horizontally, but i would like it to expand vertically.  By expand, I mean it will not use a scrollbar and will instead take up enough of the webpage as is needed to fit the tagged text.

Because this is really dumb:

Help! / How do you build a PS1 disc image from a collection of files?
« on: June 17, 2016, 10:39:49 PM »
Also what are the various ways that PS1 games load files into memory?  Is there are built-in function that does that automagically or does it need to know which sector a file is in?

If I move files around in a disc image, will the game still work?

If this is true, then the best way to deal with most games would be to dissect the disc image into files, modify those files, and then reassemble the files into a disc image.

The Lounge / What are the simplest components of a tactical RPG?
« on: June 05, 2016, 12:09:05 AM »
I must make a project of my own, and I think I should make either a Steam game or an Android app.  I'd like to make a tactical RPG, but I'm one person and there's only so much I can do.  I'm thinking that procedural generation could be a very good mechanic to reduce the amount of work involved, but I'm not sure what sort of mechanics should be involved.  What tactical RPGs do you recommend I study to find interesting mechanics that are suited to procedural generation?  What are the most basic mechanics a tactical RPG should have?

The Lounge / Galaxy Mage, a tactical RPG
« on: June 05, 2016, 12:04:30 AM »

GalaxyMage is a free, open-source tactical/strategic RPG for Windows, Linux, and Macintosh, with online multiplayer support. A tactical RPG is a type of role-playing game where turn-based battles are fought on a 3D map. Examples of commercial tactical RPGs include Final Fantasy Tactics, Vandal Hearts, and Disgaea: Hour of Darkness. Our goal is to make GalaxyMage a game that is relatively simple to pick up and play -- you can dive right in without getting bogged down in the details of the battle mechanics -- but to also allow for a lot of character development and customization. We also intend to create a unique, advanced AI system that allows enemy units to work together as a team and employ a wide variety of strategies.

PSX FFT Hacking / disassembly of FFT files with labels?
« on: December 11, 2015, 12:56:31 PM »
There's plenty of good material on the wiki, but it's hard to keep track of it all because it's split across so many pages and there is no use of labels.  Has anyone tried to make a single definitive disassembly of each file, while changing address references to labels?  It could make things much easier to modify in the future.
