Golem HP

[Kapilapis]

Has anyone ever made an ASM hack to change how Golem's HP works? I believe a Golem with only 1 HP would be an interesting idea to play around with, but I couldn't find any results when I searched.
I also tried looking at the wiki to see if I could find them address for that value and see if I could learn how to change that, but I had no luck there either.

Ctrl f golem through these pages.

Wiki:

Haven't looked at it, but with Dokurider's notes/hacks and the wiki pages, you could set the golem's "HP" to 1.

I had read those and looked through the wiki pages. I think the part where HP is calculated should be in >this page<, but my attempt to compare it to anything in the >Data/Table Locations< page was fruitless. I also downloaded the "New Asm Files.7z" and found that same routine within "New Text Document (2)". It has more notes on what each line does, but none of them say where the Golem's HP value is set.

Hi,

This problem also interests me.

I look for "golem" in the wiki (like niwit suggested)

I found those two routines  Main_Reaction_Routine_-_performs_ability_effects and Formula_01_-_06_Aftermath

In this routines, it seems that the amount of golem is stored at 8019000X (X = team) - 0x0A0C. --> 8018F5F4 (as mentionned in the Data/Table_Locations)

So i looked for 0X0AC and found this routine Main_Action_Routine_-_performs_ability_effects

Look's like there's a part of code that may be of interest in the main reaction routine and in the main action routine.

They both store the Target Max Hp as golem amount (the summoner is the target of the golem)...
I can't find anything else, and i'm not familiar with those routines, there's no return locations, i can't tell when they occurs..
I don't understand why the team as to be the enemy team..

EDIT : it's the same routine at two different links ! Probably the one to be changed

I tried changing the 0x002a in

Code Select Expand

0018bfb4: 9442002a lhu r2,0x002a(r2) Load Defender's Max HPto 0x0022 (the address for level) and it did not seem to work, sadly. Unless I did something wrong with my xml.

[Orkney]

What happens ?

Does'nt work at all ? Or remains unchanged ?

[Kapilapis]

Remained unchanged, yeah.

[Orkney]

Ok then,

if you are sure you have applied the xml correctly (to a savestate or an ISO ?)

You'll need to use a breakpoint at the golem adress and track another routine..

You also could ask on the discord, the bests ASMers may answer you

EDIT : i just read the discord channel, you obviously already know it

I decided to give this another go this morning. Turns out my hack did not [not do anything]. It, in fact, made golem have thousands of HP. For some reason trying to load Level as the HP value did not go as expected at all. But now we know we are in the right place!

Edit: I think I see the issue. HP is a halfword, while level is just a byte. So it actually loaded the Level and Brave values together as the halfword it was looking for. I tried changing it to lbu but the spreadsheet gave me an error, so... trying to figure out what I could use.

[Kapilapis]

Hope this is important enough to warrant the double post, but: I did it! After reading a few more tutorials and learning more about ASM itself, I managed to set Golem's HP to 1! Thanks a lot for locating that routine, Orkney. I wouldn't have done this without your help.

[Orkney]

Nice !

Glad to have been helpful
