Some codes aren't 5.5.2 compatible

Some codes aren't 5.5.2 compatible

I've tried codes for The BOTW and none of them work. Need to make some new ones. Just don't know how

@BullyWiiPlaza I'm sorry to bother you about your pointer searcher again, but it won't let me input one of my dumps:

The code is:

long targetAddress = -1;

try
{
    targetAddress = Long.parseUnsignedLong(targetAddressField.getText(), 16);
} catch (NumberFormatException ignored)
{

}

boolean isTargetAddressFieldValid = targetAddress >= 0;

if (isStartingAddressFieldValid)
{
    long targetOffset = targetAddress - startingAddress;

    try
    {
        long memoryDumpFileSize = getFileSize(filePath);

        isTargetAddressFieldValid &= targetOffset <= memoryDumpFileSize;
    } catch (IOException exception)
    {
        isTargetAddressFieldValid = false;
    }
}

targetAddressField.setBackground(isTargetAddressFieldValid ? VALID_INPUT_COLOR : INVALID_INPUT_COLOR);

Basically, I think the memory dump is not big enough, so what you entered is considered as wrong.

...I can't even dump right

Has anyone turned this into its own own channel for CFW like HBL and wup installer.. Would be nice to cut out a step, going into HBL everytime

I too am waiting on this. Was gonna take a stab at doing it but it's above my head. To answer your question. No it's not been done

Install haxchi. Before installing, config it to open the tcpgecko file when you hold a certain button. Then install haxchi. Then hover over the newly created homebrew launcher channel (so no need for web exploit as well) and hold the button. You should boot into the tcpgecko app.

fedora 26, jgecko u didn't load for me, java was installed.
i had to install java-1.8.0-openjdk - now it's fine

we can edit the haxchi config file on the sd card to do this, at any time, we don't just need to do it before installing, right?

Nah, but once you change the config file, you have to reinstall haxchi.

Yes, Java 8 is mandatory and then it will work on any desktop OS (more or less, there might be platform-dependent bug since I almost only program/test on Windows)

I have a quick question, do i have to install the one you linked or is the one I got from wiiu.guide ok?
The reason i'm asking is because i'm on cfw 5.5.2 and I use mocha so I want to be sure before I do anything in the end.

 

[HackingNewbie]

Install what?

 

[Lavaimp]

Install what?

Oh I meant the version of tcpgecko
but i re-read the first post so I guess I just hope that I do it right / it works with 5.5.2

 

[HackingNewbie]

I'm on 5.5.2 and you HAVE to use the one in the original post. It is modified to be compatible with JGecko U. Homebrew apps don't usually become incompatible across system menu versions.

Okay!! Thanks for the clarification. I appreciate it a lot.

@BullyWiiPlaza whenever I try to go into disassembler, I get this error on the wii u. Before you ask, I am using the latest tcpgecko and jgecko u

I think its because it starts on an invalid address to disassemble. You can fix it by going to a random address in memory viewer and right clicking > Disassemble and then itll fix that problem by changing the invalid default address to a valid one at least.
