Need Help Making A Nes Game Genie Code With Fceux

[dominater01]

so is there a way to have it right to the flash light only?

[Mezmorize]

Where there's a will, there's a way; as they say.
But, I would keep it simple for now until you have a firm grasp.

Plus, that code is like an 8-in-1.

[dominater01]

so im kinda confused how did you know that the address was D559 when in the debugger it shows d558 for the lda

im sure you explained this a thousand times but my brain wont comprehend

i know you sed to let the cheat go but if i can find the address even tho it doesnt show up it would help me make codes for other cheats

[Mezmorize]

Yeah, I have explained it quite a few times now lol.

Lets look at this same section of code:
0F: D558:A9 00 LDA #$00 [Load the value of 00 into A]
0F: D55A:8D D0 06 STA $06D0 = #$00 [Write A]
0F: D55D:8D D5 06 STA $06D5 = #$00 [Write A]
0F: D560:8D D1 06 STA $06D1 = #$00 [Write A]
0F: D563:8D D6 06 STA $06D6 = #$00 [Write A]
0F: D566:8D D8 06 STA $06D8 = #$00 [Write A]
>0F: D569:8D DA 06 STA $06DA = #$00 [Write A]

Notice how it starts at D558
And the next line is starting with D55A

You may be wondering what happened the the address between those (D559).
Remember that in a previous post I said that one address holds ONE value, yet you see two or three values after an address:

D558:A9 00
D55A:8D D0 06
D55D:8D D5 06
D560:8D D1 06
D563:8D D6 06
D566:8D D8 06
D569:8D DA 06


D558:A9 00 <-This 00 is the next address in line D559
D55A:8D D0 06 <-The D0 is the next address in line after D55A (which would be D55B) [And the 06 is one more D55C]
D55D:8D D5 06 <-The D5 is address D55E, the 06 is D55F
D560:8D D1 06 <-The D1 is address D561 etc.....
D563:8D D6 06
D566:8D D8 06
D569:8D DA 06

ok i think i know what you mean cuz i found out on tmnt for nes that the code was C67F insted of C67E it was showing me, cuz it was also A9 just like you showed me so i used the hex editor and searched for C67E and this is what it showed me



am i safe to assume that the address of 00C670 where it starts and you count up with the letters like e6 is 1 5c 2 a9 3 00 is 4 85 is 5 c2 is 6 85 is 7 c3 is 8 85 is 9 c4 is a a9 is b 03 is c 85 is d 46 is e and a9 is f

so i get the code c67f and it did something but i cant understand why im dying instantly when i put the numbers to ff insted of having max health

i mean i could be wrong but it did something on the game with what i was trying to edit

again i could be wrong im just trying to find a way thats easier for me to learn so if im wrong about the hex thing let me know and i'll try to figure out what you meant

[Mezmorize]

In the image you attached above:
C670=E6
C671=5C
C672=A9
C673=00
C674=85
C675=C2
C676=85
C677=C3
C678=85
C679=C4
C67A=A9
C67B=03
C67C=85
C67D=46
C67E=A9
C67F=FF

[dominater01]

C67F=FF Was C67F=80 i changed c67f to the compare code to 80 and the value to FF and it modified the life in the game

i think i now know what you meant cuz c67F was the number i had to change which was 80

im just now trying to figure out why im dying instantly insted of having max health

What is the RAM address or whatever and I'll show you another example of 'converting' it to Game Genie?

[dominater01]

the ram address is 0077:FF and you get C67E is the lda

for TMNT 1

[Mezmorize]

Well, when it's putting 80 into the RAM address when starting a new game; that IS full health.

You need to be using a debugger break, after taking a hit, and stop the decrease/store.

Edit:
Once you get hit by an enemy, the debugger will break here:
98E3:99 77 00 STA

Using the simple opcode list I linked to earlier:
http://gamehacking.org/library/169

You can see that the 'opposite' of the 99 (STA) would be B9 (LDA).

So this could be a code:
Address Compare Value
98E3?99:B9

Encrypting that will give you a code that's already on the database:
OUVPUEOO

[dominater01]

man that op code list is very helpful thanks for showing me that list

the cheat might be in the database already but i was just trying to learn the basics b4 i make a new one

[dominater01]

i found out how to convert 6bit game genie codes into 8bit so i converted alot of my codes already
