A problem with Castlevania SotN code creation

[Flightless Wren]

Okay, some of you know, from my Suikoden 3 topic, that I've tried hacking this game a bit. Specifically boss hp values. Well, my problem was pretty simple but I really don't know my way around the shear mechanics of a game and so I can't really say where I went wrong.

I've spent some time trying to find boss max hp values so I could create a mod through codes. I would like to increase the difficulty of the game... but... I have encountered problems.

Okay, while looking for the boss hp I rather easily stumbled upon current hp values for a few bosses. I went up to boss 4 or 5, I think, and then I encountered a shared value in the games code between the first boss and the last bosses hp that I found... this was somewhat disheartening; moreso than not being able to find max hp values.

I notice that in your official request page these codes are listed... so, what is the problem with creating them? I was all for making them for you to host... but like I said, I'm stumped. I went through each value in the game (only the ones that were the same as the bosses starting hp of course) one by one trying to find the value of the first bosses hp and lock it at something higher, but the current hp never changed.

The problem with creating the boss hp mod codes is that several bosses share the same address. I spose this could be fixed with a debugger or some kind of joker code. I actually have the codes, but Im waiting to get another psx so I can fix the codes myself.

I'm not sure, but often in a case like that, there's a variable somewhere that will change depending on the boss currently being fought. Only way to find out is to look. Might be a total pain to locate if it's even there.

If the HP is there, then are there other stats nearby, like attack damage and such?

I'll see what I can uncover in the next day or so. Right now it's late and I should really be getting to bed... heh, it's 3:37 A.M. where I am.

Anyway, when I get some time I'll see if I can locate any more of the bosses values. Probably have something to post before the weekend is over unless real life sneaks up from behind the bushes. ;D

I didn't examine those HP value things too much. But I know they work. Really all it needs is a Room ID Joker code combined with the hp mod to work I think. I got both. I will hopefully be getting a playstation in 2 weeks. So if noone comes up with the codes by that time I will post them.

I guess I got atk and def mod codes too. Its only for a few bosses tho.

Well if you have the codes I guess I'll just wait to see what all you have, then help you find the rest if you'd like. I'd just like to point one minor thing out I noticed in my testing. The current hp mods do not influence the bosses change in tactics (unless your code is different from mine). Let's say boss 1 would enter his harder mode when he reaches 50 hp left (of 200) and you hack his current hp to 2000. The boss would still only enter his harder form when he reaches 50 hp and not 500.

I was hoping that a max hp mod would solve this little problem.

If you got working HP mods you might as well post them and I'll put them on the site. I doubt the one I have is gonna be any better.

Here is an example of the atk and def mod codes that i have.

slogra atk mod
D0076ec0 4778
80076ed8 ????

slogra def mod
d0076ec0 4778
80076ed2 ????

Digit value cannot be too high or the game will freeze. 0 - 190 is reccomended.

actually, it seems like these codes have the same problem as the hp mod codes. they share the same address among other bosses. Cause I see that other bosses have the same address for def and atk.

I think I remember back when SOTN hacking was huge here at GSHI years ago that someone was working on codes to make the bosses harder. About the only one I saw was one that made that diamond crash always hapening in the Richter battle. It's pretty tough to get this game a good kinda hard mode hack.
