[Hidden-Palace]Biohazard Betas Released

[kevstah2004]

Finally got the SOUND TEST working :-)

Controller 2:
SOUND TEST = D-pad changes the X and Y values.
Press triangle to stop playing the current BGM.
Press square or X to play.

Easier way to access the options screen since it's also tied to the inventory start and debug menu select, pressing just select+start doesn't always trigger it

Options = Press select to first bring up the debug menu, then hold start and press select

Is there anything special about the sound test I missed?
It only plays a limited amount of sfx available in the room you are currently in from what I have seen so far...
(Perhaps there is a way to play all sfx from within any room but in this case I don't know how)

Well, try playing around with the voice test instead, it produces much more interesting results!
Plus it's just fun to be able to replay some hilarious lines of bad voice action over and over!

I've just tried it inside the caves!
You'll be able to hear some weird stuff like "Oh Barry, I'm so scared" as well as the whole "Enrico thinks someone's a traitor" dialog there!

IDK, I think another combo is needed to switch between them maybe the shoulder buttons of pad 1 or 2 atm i'm only getting it to play the last played sound such as a door opening

I still can't find the scenario address, it doesn't seem to follow the normal values of
00=Chris, 01=Jill, 02=Barry, 03=Rebecca
in this debug build, here's some save sates in epsxe to see you can find it.

0 = Chris saving Richard.
1 = Rebecca not grieving over Richard.
2 = Rebecca Scenario.
3 = Rebecca about to save Chris.
4 = Water Gate room for enemy tests.

How to check it? ehm

[geluda]

Does anyone know what this says? I get this message quite a lot when I'm messing with stuff I'm probably not supposed to...

Taking a break from the playthrough today, spent almost all day working on it yesterday, gonna have a mess around today and have some fun!

[kevstah2004]

Place files in the epsxe save state folder "sstates" press escape once the game has loaded, click the run tab then load any of the 5 states, you may need the same plugins setup as me i'm not sure.

After extensive testing i've found only these work as safe replacements over Kenneths slot, for some reason overwriting the grounds keeper zombie only changes his AI.

00 - Researcher Zombie
01 - Naked Zombie
02 - Cerberus
05 - Crow
0F - Plant root - "Guardhouse"
11 - Grounds Keeper Zombie
All S.T.A.R.S. members too.

[geluda]

Kev, I think I got CEP working, thanks! I got walk through walls to work, although I'm still having a few problems with some things... Do you have a link to all of your codes for this game? Same thing to you Upa?

No, I know how to load savestates

I just tough you mean to check with and hex editor how the game react in that area

カギがかかっている Because they are key (what?!)

Maybe I've draw it wrong, but it seems correct

[kevstah2004]

Yes but I don't know how to do memory dumps within epsxe, I think you can via PEC but I don't use that.

[geluda]

Thanks! Is the effect always the same? I can it depend on what platform you're using? I.e. console, emulator etc? I tried to play as Barry in 04/01 and it's kind of broken to say the least lol. I can only get some codes working if I use them before I load the game, a lot of the time the codes wont work if I use them while the game is being played.

Also, what do you mean about doing memory dumps?

[kevstah2004]

Yes Barry is semi broken he constatly runs or does that kick animation when walking baackwards. You can solve the running by room warping to the dining room.
What codes are posing a problem for you?

I tried the weapon modifier but not sure how it's supposed to work. I used the knife and changed the values but chris kept doing this weird animation and it had no effect on an enemy...

[kevstah2004]

You need to change the weapon values whilst the inventory screen is open otherwise it'll only load up the animation, you can't do this in the (04 August 1995) sample though so just use circle to swap between the available weapons instead.

[MarkGrass]

Whoa! Excellent find!

...I hope there's as many people interested in hacking/discovery, when Bio Hazard 1.5 gets released.

[geluda]

Got the hang of it now, thanks!

Something I noticed, you know how we were getting those crashes when we warp? That's because at whatever part of the game we happened to be in, Stop Flags were preventing you from moving!



These two flags represent player movement, why both of them, I'm not sure. However, point is, if you ever teleport and your character freezes, it's because one of these flags is preventing you from doing so! I can't say why they end up that way, I don't see why teleporting from one state (i.e. a cutscene) into a different room would result in the allowed behaviour in that room to be different... :/

Found a nice way to exploit things with the stop flags. Normally you're not allowed to move during cut scenes, using stop flags we can, but only with a trick. Checking the two player stop flags isn't enough; I'm not sure why this works, but by checking the blue stop flag, which is the flag that allows us to bring up the Inventory menu, as well as the player flags, we can enter the menu and upon exiting, we can move around (weird, I know).



This took a while to do! Messing on with the game's frame advance feature I managed to do the above before the scene changed. Also the green flag seem to stop the current active portion of the cut scene. Cut scenes seem to play out in small individual pieces, stopping the scene with this flag before the game auto changes the individual piece will indefinately freeze the scene (once this portion of the scene ends) untill we uncheck the flag and allow it to continue. Edit: This seems kind of iffy, some times it works, some times the game will auto change the scene anyway, debug menu seems to continue the scene, also it doesn't reactivate cutscene freezes from the debug menu. Kind of iffy...

What does this text say (the dog text?)? Strange bug with this; clicking on the door brings up this message, I assume says something like "I must go and investigate," and wont let us watch the cutscene with the dogs. But for whatever weird freakish reason, pressing select and bringing up the debug menu will run the FMV. NO IDEA why that is or what messed up piece of code causes that to happen, but yeah.

This build is amazing, and at first I thought it was incredibly buggy, but once you know what's what the amount control you have exceeds anthing I've ever seen from a feature like this. Only thing that's missing is a weapon mugen, but even without that there's so much here it's pretty much irrelevant.

Another thing I noticed is that during cutscenes the game switches the camera view option in the debug menu to manual so the cutscene can control the camera angles instead of the player. Switching it back to auto allows us to move around in cutscenes AND change camera angles, possibly to angles you've never seen in a cutscene before, if you so did wish. However trying to do this brings a lot of problems and you have to muck around with things, try glitching it out and tricking it into working, I'm not sure how far doing this goes.



One thing that's for sure though, is that messing with stop flags screws with the game, some really weird things start happening!

[kevstah2004]

Taken from the Birth of Biohazard video. I'm guessing these are decimal values and not hex for the easier BIOHAZARD game, Jill having the lower value and Chris the higher, I can't remember which way around it is, but I think Chris has a bit more health than Jill, 8C = Chris vs 60 = Jill, Jill and Chris's weapons differ in power as well. It'll be interesting to know the damge of every enemy attack, the Hunter only seems to try and perform a leaping decapitation if you health has dropped down to a certain level otherwise it just swipes at you instead and the zombies puke acid at you in certain rooms, normally the two landing staircases.

The Yawn completey owns Tyrant , it didn't show the Neptune or Plant 42 HP values unless I missed it.

Yawn (1st stage) HP 3050
Yawn (2nd stage) HP 300

Tyrant (1st stage) HP: 220
Tyrant (2nd stage) HP: 600

Black Tiger HP: 204
Web Spinner: 89 ~ 119

Chimera HP: 80 ~ 122
Hunter HP: 79 ~ 111
Cerberus HP: 59 ~ 119
Zombie HP: 39 ~ 99
Wasp HP: 20 ~ 60
Crow HP: 10 ~ 52

About the STR player I got a wierd bug happen to me when it tried to replay the prologue FMV the mdec glitched and made the fmv appear it heat vision, it looked kinda cool with my 3d specs.

I "try" to keep my website up to date with all the cheats I have created,
but by the amount of codes we're hacking and posting in this thread everyday I don't feel like updating my site after every new post I make...
The whole AI and Event Modifier stuff is not on my site yet...

At the moment, all my Biohazard Sample cheats are scattered around this thread but I think I'll keep some kind of link list which brings you to the right posts in the future! For now, here's my PSP cheatfile with a bunch of codes for all kinds of PSX RE games, you might want to try that for a good database of codes to try!

I'll create a list of all recent codes sometime this weekend!
A friend comes to visit today and I don't want to bore him with code hacking stuff he knows nothing about...

@kevstah2004:
For the Scenario Modifier, I'll try to find it as soon as possible! (Which would be sometime this evening)
It can't be impossible to find! It might just be in a different location than the usual place because of the debug stuff or whatever else they've changed in this build...

Also about replaying the FMV, I've tried that too!
There's a certain value which is usually 80 during gameplay, if you mess with it you get weird graphical glitches, collect a shotgun which freezes the game or replay the intro FMV in "heat vision" which also freezes the game!

I can't look for it now, but I remember it being just a few bytes away from the amount of enemies in room modifier I posted earlier!
This one:

10/04 build:

Amount Of Enemies in Room
300C000E 00XX

V-Jump build:

Enemy Counter
300C6012 00XX

It's always the 80 near that address, in every Biohazard game and even in Biohazard 2 & 3!

[kevstah2004]

Odd thing is in Rebecca's scenario you can access rooms which should be blocked to her path by displaying a message but you can freely enter the rooms willy nilly

[geluda]

Think I messed up the images in my last post, fixed them...

[SonicBlue]

外に出るのは危険だ・・・! It is dangerous to go out!

the other one:

ごめんなさい I'm sorry
確認したんだけど・・・! I was confirmed! (?!)

Those damn Chinese ones are too difficult to draw, also I don't know if they are correct
