[Solved] Binary Operations (8-Bit AND, OR); Set/Enable/Disable certain Bits with Gecko?

hello there,

i'm trying to create a code where i only have to change a certain bit.
(the other 7 bits of that byte at that address shall keep their old value)


as i'm more used to playstation 2 code formats, i'll give an example how it is done there (type 7 code)
MH2 Enable Symbol Colors
705D4ADA 00000040
MH2 Disable Symbol Colors
705D4ADA 000200BF

short explanation:
1.
at address 0x005D4ADA, do (loaded databyte OR 0x40) => write result to 0x005D4ADA
=> or in other words: bit 7 is set to 1 and all other bits remain the same
2.
at address 0x005D4ADA, do (loaded databyte AND 0xBF) => write result to 0x005D4ADA
=> or in other words: bit 7 is set to 0 and all other bits remain the same


is there an equivalent in gecko   


i couldnt find anything at http://geckocodes.org/index.php?arsenal=1
(if its there, then i couldnt figure it out by the explanations given)

thanks alot for answers  

[EDIT]: Solution Overview (ba+ memory)

Code:

Set certain bits to 0
82010001 xxxxxxxx
86300001 000000zz
84010001 xxxxxxxx

Set certain bits to 1
82010001 xxxxxxxx
86200001 000000yy
84010001 xxxxxxxx

xxxxxxxx: ba+address of 8 bit value which contains the bits to be changed
yy: bit to be set to 1 (ex.: yy=0xD1=[binary:]11010001 => changes bit 1;5,7,8 to 1)
zz=0xFF - yy: bit to be set to 0 (ex.: zz=0xFF - yy= 0xFF - 0xD1 = 0x2E=[binary:]00101110 =>  changes bit 1;5,7,8 to 0)

1) Load into Gecko Register
2) Gecko Register / Direct Value Operations
3) Store Gecko Register at

oh ok thanks :)i thought there was something easier

also, i've never created register codes, so will any register work?

or could u give a link for an example (im quite confused with the register code explanation given on geckocodes.org)

I'm just wondering. Do you have a USB Gecko?

no im using the dolphin emulator technique

(creating ramdump with HxD and testing out codes with dolphin)

I'm sorry to say, but it's impossible to make proper codes with Dolphin! Also, you can't do ASM codes with Dolphin and especially, just a RAM dump. You need to get a USB Gecko and they don't make them anymore. If you know computer hardware and shit, you can easily build and program your own, but it's better to just buy one. Also, you can't buy them from retail, you have to buy them online. And most of them aren't cheap. I got mine for $15 because I got it from a very good friend and it came all the way from Germany too!

hm? my codes are working fine ... even when im testing them out on my wii

and some code injection codes i found online r working fine on dolphin, too. (im using dolphin 4.0-1107)




anyway back to topic

some questions came up:
1.
Load into Gecko Register "82UY000N XXXXXXXX": what does grN mean and what do i set the "N" to (or in which range could it be set (i mean can it be all possible values 0..F or is there some restriction)
[EDIT]: i chose N=1 and worked
2.
Gecko Register / Direct Value Operations "86TY000N XXXXXXXX": so Y can be 0/1/2/3 but whats the difference or better say, what those [values] in brackets mean (is it pointer/address?)
[EDIT]: i used digit for no []


explanation much appreciated
*looks at Bully@Wii-Plaza's direction*

Ha! LMFAO! I said PROPER! Dolphin runs on the PC and EMULATES the Wii games. The PC and Dolphin emulates the games not the actual hardware and software of the Wii! Therefore, everything is completely different! Also, earlier you had said you make RAM dumps with HxD? Are you opening up the RAM of Dolphin in HxD? If you are, you are doing it completely wrong! xD There's a much easier way within Dolphin itself, but even that doesn't give you the actual RAM dump because your PC doesn't run with Wii hardware and software. If you want to make codes, get a fucking USB Gecko!

Also, take a look at this:

As long as they also work on a real Wii it shouldn't matter

thanks for tut-link, i always wanted to read something like this but never actually found a tut (tho i didnt actively searched for one )

i like that attitude  

@Bully

Yes, but you should always test it on a Wii, which is what he did and said it worked. I'm just saying you should always test the codes you make in Dolphin on a Wii.

yea first i make codes with dolphin/test them on dolphin until they work (i think with dolphin, its quite fast to test/changecode/test again)

then i do final test on wii console *working as expected, yay  *

I use the USB Gecko because you don't have to reboot the Wii and reboot Gecko OS to modify the GCT. xD

as i dont have usbGecko ...i didnt knew you could create gct's on the fly

that sounds nice+fast (can crash wii if new faulty codes are applied?)

Yes. But I mostly use it for testing codes that I make with the Gecko or for adding random codes that I know that work.

If you crash the Wii, you usually have to restart. The USB Gecko is no protection against it but an error can be caught and fixed eventually.
