Question for Pugsy
Hi, Pugsy!
You can help me? Please!
I would like find some MK cheats in MK rom using WinHex to get find other cheats, but I find only
when cheats is in this format (start with 399).
Look your cheats for exemple:
:mk:39900000:09425C:00000300:FFFFFFFF:Always have Reptile Clues
To find the value in rom, I used this calculation:
9425C / 2 = 4A12E
:mk2:39900000:00385C:00000300:FFFFFFFF:Always have Smoke/Jade Clues
385C / 2 = 1C2E
All cheats starting with 399 I get every using this calculation and when I find in rom, I get convert to cheat format using the inverse calculation.
Now I try find this cheat using this calculation:
:mk2:39800000:03677F:000000C0:FFFFFFFF:CPU always finishes with a Fatality
3677F / 2 = 1B38BF
Ok, I find this value 1B38BF but when I changing to 00C0 in rom, the game crash!
Note: This cheat starting with "398".
Or in this exemple:
:mk:39800000:094C0B:000000C0:FFFFFFFF:Always Get Secret Game Over Screen
94C0B / 2 = 4A605
I find this value 4A605 but when I changing to 00C0 in rom, the game crash too!
Note: This cheat starting with "398" too.
Well...
***And which calculation I use to find the position in rom how in this exemples?***
:mk:00000000:20A264:00000002:FFFFFFFF:Get Double Flawless Bonus
20A264 / ? = ?????
:mk2:00000000:20C368:000000FA:FFFFFFFF:Always Play Pong After First Round
20C368 / ? = ?????
:mkla3:00000000:2099C8:00000006:FFFFFFFF:Night Fight
:mkla3:00010000:2099C9:00000000:FFFFFFFF:Night Fight
2099C8 / ? = ?????
2099C9 / ? = ?????
Thanks!

Re: Question for Pugsy
Cheats with a type of 399xxxxx will poke a word (16 bits), and cheats starting with 398xxxxx will poke a byte (8 bits) - so you don't poke 00c0 you poke c0 - poking the extra 00 will crash the game.
As for cheats starting with 00xxxxxxx, they are RAM cheats so they do NOT correlate to a ROM address at all.

Re: Question for Pugsy
Hi Pugsy
I have here a code for Ultimate Mortal Kombat 3 and would like to make the change directly in the rom.
The code is:
:umk3:39900000:002174:000009E5:FFFFFFFF:Explosive Kombat:Only for 2 on 2 Endurance
:umk3:39B10000:002176:00227227:FFFFFFFF:Explosive Kombat (2/2)
Well, for the first code: address 2174/2 = 10BA
In this ROM address I write in um312u54.bin 09 and in um312u63.bin E5 right?
Ok, for the second code: Address is 2176/2 = 10BB
BUT, the changed values is 227227
How I'll write 22 72 27 in the same ROM address that I only have two files to write?
Thanks in advance and sorry bad eng.

Re: Question for Pugsy
For starters, it's a longword write so that's four bytes not three.
It's 00 22 72 27 you need to write to the two files

Re: Question for Pugsy
hmmm... ok, step by step of what I tried:
The first code: :umk3:39900000:002174:000009E5:FFFFFFFF:Explosive Kombat:Only for 2 on 2 Endurance
address 2174/2 = 10BA
In this ROM address I write in um312u54.bin 09 and in um312u63.bin write E5
-------------------------------
The second code: :umk3:39B10000:002176:00227227:FFFFFFFF:Explosive Kombat (2/2)
address 2176/2 = 10BB
Well, I have to write 4 values: 00 22 72 27
But the cheat points only address: 10BB
I tried to write values from this address on:
from 10BB writing forward (in both files):
00 (in offset 10BB)
22 (in offset 10BC)
72 (in offset 10BD)
27 (in offset 10BE)
That did not work.
I also tried to write interleaving byte-byte in both files but also did not work.
Could you please explain how to write these values and at what addresses?
Thanks in advance!

Re: Question for Pugsy
I don't write to files, I use cheats to change ROM addresses on the fly - so I think you have a bit of a cheek asking to be honest.
I don't mind giving pointers, but what you are asking is basically just to tell you what to do and spend time looking at the source and the debugger and opening the ROM in a hex editor (not happy).....
at 10ba-10bc in one file write 09 72 00
at 10ba-10bc in the other file write e5 27 22
and make sure you change the right files, I think you may have them arse about face

Re: Question for Pugsy
Hi, Pugsy!
Is possible make the change directly in the Snes rom using Pro Action Replay or Game Genie cheats too?
For example, I have this cheat for Super Metroid for start with Hyper Beam - 7E0A7760 (Pro Action Replay), 62C5-14A6 (Game Genie Code).
Is possible change directly in rom?
Thanks!

Re: Question for Pugsy
As I said to you in the last PM I don't know much about the SNES.
There are tools out that are supposed to do what you want, google is your friend.

Re: Question for Pugsy
Right. But I tried some information and tools and unfortunately I don't have sucess...
And I don't have a great knowledge about the cheat as you.
Thanks, Pugsy!

Re: Question for Pugsy
Well I've never applied SNES cheats to ROMs either. Did you try ucon64?
