Hacking Sequential codes PSX

[jin299]

Great new man I finally found the Bison II flag code, I found it with cheat engine would you believe, he is now playable in all modes with his white costume just like the cpu,also with this code all the cpu bosses can also use there cpu intro's too.

Now there's a few problems with the code, When playing as Bison II in his white costume, If you use him in practice mode the game will freeze during gameplay, i don't know why this happens, I don't think there's a way of preventing it.

And when you win a match while using him it saids you lost the match, and the opponent won, is there any way around this because If you play against the computer in the vs Bison II bonus match, when he loses the match it's saids he won?

How do I hack a code that tricks the game into thinking he won the match,as oppose to saying he lost?

[Helder]

Well since he isn't normally playable the game assume anyone besides him is human controlled. You might have to check the routines for rouns won and there should be a conditional branch that is specific for him.

[jin299]

Helder would that require ASM hacking to accomplish this?

Anytime I pick Bison II and enter arcade mode as player 1 the other No Bison II flag appears as the the opponents instead,
and I tried hacking tried using a always win modifier code to try and bypass this problem, but all It keeps saying is Bison II no flag lost the match, when winning the match with Flag activated Bison II?

Also I had a theory so I decided to test it after I had exited arcade mode and turned off the bison II flag, and left on the normal Bison II character modifier code, i then entered versus mode I then noticed that the Bison II flag code was still somehow enabled, so I played versus mode while playing as Bison II in his white costume and won the match and it said winner?

So is it possible to make a D commander code out of it because i have already doing tried that but couldn't get the code to execute at the right time during the fight?

[Helder]

Post your codes and what is required to make it work and I will look at it.

[jin299]

Sure thing Helder

Bison II Character Modifier PLAYER 1
301E7FD2 001B

Bison II non flag
301E669C 0019

Bison II flag
301E669C 001D

I should also note that in order to load the Bison II flag code it needs to be loaded along with his character modifier data to work.

[Helder]

Ok give me a few days till I have some free time.

[jin299]

Helder this is the best code I could come up with it lets me win a match as Bison II in arcade mode the only problem is I keeps facing the same opponent I already beat? example say I fought Rosso on the first stage, well then I'll face Rosso again on the stage 2 and 3 and onwards?

301E7FD2 0015
D01E669C 001D
301E7FD2 001B
D01E669C 0001
301E669C 001D
D01E7FD2 001B

I found a moon jump code for Street Fighter Ex2 Plus it's pretty cool.

301E800A 00FF

Helder there is something i have to ask you because it's something that has easily confused me, I found a disable fireball code for Street Fighter Ex2 Plus, but the problem I'm having is with the unknown search value

if I search unknown value when standing still in the fight and then fire a fireball and search increased value then stand still and search decreased value, I can find the code by doing that

However if I first fire a fireball and then search unknown value after it, and then fire another fireball and search increased value and then stand still and search decreased value, the code won't appear on the list?

Helder I'm trying to hack a code that controls who does there pre animation intro in Street Fighter Alpha 3 I have tried to find the code by comparing each intro to one another using different to searches in the game but found nothing I'm not sure whether or not a code of this sort can could hacked through ram hacking?

A good example of a player who does his own special intro in the game is Balrog the boxer in the game the cpu version of him in the game has his own pre animated intro before the the fight, I'm trying to figure out the code for what controls that intro, so that I can perform it before the fight i was thinking It might be another flag code of some sort, but I'm not completely sure if it is?

[Helder]

More than likely it is, try having the cpu controlled Balrog have the intro then do an initial search and while he is still doing the animation do an equal to. Then press Start on player 2 pad and choose Balrog again and when the fight starts where there would be an intro do a different than search, rinse and repeat till you find it.

[jin299]

when choosing player 2 Balrog and searching different to search do I need to make him do his cpu intro or his human controlled one?

[jin299]

Helder I think I found something but have no idea how to make a d command code out of it it's a sequence of Balrog cpu animation

801942B6 00?? sequence values range from 0 to 7

[Helder]

It's simple to do just use the same address as the comparator so for example:

D01942B6 0000 <-- if equal to zero go to next line
801942B6 0007 <-- constant write if conditional is true

[jin299]

I already tried making a d command code out of the sequence and It just woudn't work out?, I had
to activate the code as the following for it to execute the next lines of the code, any reason why the code won't function correctly?

example If I put the values 0003 into the code, the punchbag from the celling appears but Balrog doesn't, and the game hangs if I enter 00007 Balrog appears and does his dashing uppercut but does it constantly to the opponent, values 0006 Makes Balrog hit the punchbag, you can hear him hit it but Balrog is not visible on the screen during this time?

D11942B6 00??

Could you check it out for me?

[Helder]

Use the debugger for things like this, it seems like this address is used for many things besides the intro and if you lock it in then it never leaves the animation sequence.

On the debugger I put a break on write and read since I wasn't sure which would have something useful and I got this when the match starts:

801BEA14 90820006 lbu v0 ,$6(a0)

register a0 has a value of 801942B0, so this is adding 6 to the address so we get 801942B6 our code for animation and then loads the value to register v0. So what do we do to make it load our chosen value? I'll let you give it a try then I might help but you need to do this yourself to learn. Of course this might affect other things besides player 1 intro animation so testing is needed.
