PS2: Code Condensing

[GameMasterZer0]

Important: The whole thing would only work if there is constant difference between the codes! In this example the difference is 1


Example:

00000000 00000063
00000001 00000063
00000002 00000063
00000003 00000063
00000004 00000063
00000005 00000063
00000006 00000063
00000007 00000063
00000008 00000063
00000009 00000063
0000000A 00000063
0000000B 00000063
0000000C 00000063
0000000D 00000063
0000000E 00000063
0000000F 00000063

this is our Main - Code which have 16 Lines. But with condensing we can make this much shorter!




16 Byte Condensing


Whats happend with our Code if we make a 16 Byte Condensing?(The Code above runs in 8 Bytes. This you can see because of the "0" in front of the Code)?
The whole code would be halved!

10000000 00006363
10000002 00006363
10000004 00006363
10000006 00006363
10000008 00006363
1000000A 00006363
1000000C 00006363
1000000E 00006363

We see that the first Numbers have changed (0 -> 1). This "1" say that the codes runs now in 16 Bytes!
1xxxxxxx0000???? (before 0xxxxxx 000000??).

We also see that difference between all Codes have changed (1 -> 2). One 16 Bytes Line takes over the work of two 8 Bytes Lines! But we have to include the Digit from the lost Line in our 16 Bytes Line (63 -> 6363)

But we can still condense more lines!




32 Byte Condensing


What happend to our 16 Bytes Code if we condense it to a 32 Byte Code?
It is halved too or quartered if we see our Code in the beginning!

20000000 63636363
20000004 63636363
20000008 63636363
2000000C 63636363

We see that the first Numbers have changed (1 -> 2). This "2" say that the codes runs now in 32 Bytes!
2xxxxxxx???????? (before 1xxxxxx 0000????).

We also see that difference between all Codes have changed (2 -> 4). One 32 Bytes Line takes over the work of two 16 Bytes Lines! But we have to include the Digit from the lost Line in our 32 Bytes Line (6363 -> 63636363)

But we can still condense more lines!



32 Byte Super Condensing


You would ask how you can condense a Code whichs is already running in 32 bytes......

40000000 00040001
63636363 00000000

How this code is build ?

40000000 <-it is the first Address but instead of a 2 we have now a 4!

0004 <- This shows how often 32 bytes is include in this Code!

0001 <- this shows how many lines are calculate between the difference (At this example every, cause the Difference is 1 in the orginal of the Code!

63636363 <- Digit / Value

00000000 <- this is just a kind of verifier... you can use what want (e.g. DEADFACE ^^)

In variable:

4aaaaaaa xxxxZZZZ
bbbbbbbb 00000000

aaaaaaaa <- the Address which our Code begins
bbbbbbbb <-Digit we have to choose

but how we get xxxx and ZZZZ?

We have to take a Hex/Raw - Calulator e.g. the Windwos - Calculator.

We count how many Adresses our orginal Code have ---> 16 but we have to convert it in Raw/Hex --->10!
Now write in your Raw/Hex - calculator... 10 : 4...-----> = 4

Now our code is:
40000000 0004ZZZZ
63636363 00000000

Now we only have to find "ZZZZ"

This value indicates how many Lines are jumped over to the next Code. This system only runs with32 Byte. You just choose 2 Codes which stands among themselves. (just use the Addresses)

20000000
20000004

---> 20000004 - 20000000 = 4

This we have to divide with 4

4:4 = 1

Now our code is complete!

40000000 00040001
63636363 00000000

The same method on another example

Address 1 -> 20000008 12345678
Address 2 -> 2000009C 12345678

we see the Code runs already in 32 Byte

2000009C - 20000008 = 94 ......----> 94 : 4 = 25 .....

40000008 00020025
12345678 00000000

why 0002?
Because 32 bytes are 2 times include in this Code

Note: for this method our first Adress of the Code have to lie on 0, 4 , 8 , C !!! Otherwise you have to take one Adress before the condense Code!

Example:

"unlock all the movies"

Raphael
003FBF73 00000003

Talim
003FBF74 00000003

Yunsung
003FBF75 00000003

003FBF76 00000003

Mitsurugi
003FBF77 00000003

Taki
003FBF78 00000003

Voldo
003FBF79 00000003

Nightmare
003FBF7A 00000003

Astaroth
003FBF7B 00000003

Ivy
003FBF7C 00000003

Kilik
003FBF7D 00000003

Xiaghua
003FBF7E 00000003

Maxi
003FBF7F 00000003

Necrid
003FBF80 00000003

Heihachi
003FBF81 00000003

Sophitia
003FBF82 00000003

Seung Mina
003FBF83 00000003

Yoshimitsu
003FBF84 00000003

Charade
003FBF85 00000003

Cervantes
003FBF86 00000003

would be

003FBF73 00000003
403FBF74 00050001
03030303 00000000

we see the first Adress of the Code dont lies on 0 , 4, 8 , C so we just take this line before the condense Code!!

Is there a tool to un-condense codes? PS2 patch engine won't work with them and I suck at math.

I was talking about a code that was already condensed by someone else, I can't seem to figure everything all out about it. Here is the code below:

40534CB4 00100005
00000000 00000000
40534E08 00040005
00000000 00000000
4054B5EC 00100005
00000000 00000000
4054B740 00040005
00000000 00000000

I thought I had it all un-condensed but I didn't, the codes froze the game up when it originally wouldn't.

I was talking about a code that was already condensed by someone else,

yes I know that

I can't seem to figure everything all out about it. Here is the code below:

40534CB4 00100005
00000000 00000000
40534E08 00040005
00000000 00000000
4054B5EC 00100005
00000000 00000000
4054B740 00040005
00000000 00000000

I thought I had it all um-condensed but I didn't, the codes froze the game up when it originally wouldn't.

condensed code#1
40534CB4 00100005
00000000 00000000

condensed code#2
40534E08 00040005
00000000 00000000

condensed code#3
4054B5EC 00100005
00000000 00000000

condensed code#4
4054B740 00040005
00000000 00000000

For example

condensed code#0
40534CB4 00100005
00000001 00000000

you will need Windows Calculator in Programer Mode to convert HEX to DEC

in the Condensed .NET app

40534CB4 change to 20534CB4 copy and paste into the "Start Address" text box

HEX 0010 convert to DEC 16 copy and paste into the "Total Lines" text box

0005 Full Word count
4 Full Word count 1
8 Full Word count 2
C Full Word count 3
10 Full Word count 4
14 = Full Word count 5
00000014 copy and paste into the "Address Increment" text box

00000001 copy and paste into the "Start Value" text box

00000000 copy and paste into the "value Increment" text box

then click on the "Create Uncondensed" button

Thanks lee, if not for your post I would have never figured that out. It would be cool though if you could just paste the condensed code in and it auto-un-condense it.

Okay hopefully this is the full un-condensed code:

Okay hopefully this is the full un-condensed code:

Its look confusing at first but its simple.

where is the fun, in that?

looks fine.

Well it was kind of frustrating for me at first as I had 3 other codes to convert, but in the end they all work as they should.

I made sure I pasted that info you wrote into a text file for future reference. I doubt I'll ever use codetype 4 though you never know, if perhaps sometime in the future I can memorize how everything works I might just use it someday.
