Is there a Skies of Arcadia encounter rate mod?

[fafadou]

I disassemble the code in order to see if I can do something :

Code: Select all

8d f3 06 d3 38 f2 34 f2 05 89 05 d1 12 62 01 72 22 21 07 a0 09 00 e8 a1 09 00 00 00 0c 0c 57 8c

Just the original code before @pomgd patch, I used IDA :

There is something strange for me the pointer 8c570c0c is beyond the 1ST_READ.BIN, how can I locate it please ?

If you do not press anything, you will not be encounted.
Pressing the B button for a while will cause an encounter.

[Dakangel]

While pressing the B button, you will not be encumbered.
Therefore, there may be imperfections.

I analyzed it myself.
"05 8b" part might be better as "05 89".
In this case, it does not encounter during normal operation, but only while the B button is pressed.

If you do not press anything, you will not be encounted.
Pressing the B button for a while will cause an encounter.

So ,to patch a gdi image is just to replace the code with an hex editor and thats it?

Normal game behavior and only force to stop the heavy rate encounter entirely when the player press and maintain the (B) button (05 8b) if desired as an option (for a hacked game) is better.

But there isnt need to be the (B) button like the gamecube version, in fact that button is on the oposite side in the dreamcast controller (Must be (X) in the Dreamcast one)

@pomegd : is it possible to play directly with the encounter value please ?

[pomegd]

Code: Select all

encounter value(increased by walking)
8C4ECCE4 xxxx

default threshold
8C0DAA5A 01E0

If the value of the encounters exceeds the threshold value, the fight is randomly shifted to a battle.
You can change the encounter rate by changing the threshold value.

Thanks you very much @pitito tried to help me but i'm not focus yet due to personnal reasons.

I look at this, this evening

[fafadou]

I had no fight even in boat with your patch dear @pomegd :

About your last post :
There is only one encounter threshold ?
Could you tell me how you have find it please ?

Else thank you very much

[pomegd]

If you check the part that refers to 8C4ECCE4, you will find several references to it.
Among them, find the part where the value of 8C4ECCE4 is used as a condition for branching.
Then you will find that the value to be compared in the branch is the value of 8C0DAA5A.

Is there a way we can get the encounter rate to be permanently cut in half? A patch like this would be super handy.

[fafadou]

Please try m'y release and tell me.
It's what i tried to do.
