Hacking Cafe OS Breakpoints

[BullyWiiPlaza]

I'm wondering about the current state of setting breakpoints on Wii U games. Since the IOSU exploit is going to be released soon, does this in any way mean something for breakpoints? I believe they are already possible just with the kernel exploit but it just hasn't been made/published yet.

Then there are also 3 different github repositories for TCP Gecko.NET sorted in last updated comes last in the list:
https://github.com/Chadderz121/tcp-gecko-dotnet
https://github.com/dantarion/tcp-gecko-dotnet
https://github.com/wj444/tcp-gecko-dotnet

They all seem pretty inactive but we really need a good RAM debugging tool and TCP Gecko.NET currently is the most complete one we have. Is there a chance for breakpoints to return soon?

Thank you

Some people do have breakpoints but keep it private.
@Mathew_Wi @crediar @Marionumber1 any change we will see this option public soon?

No need to give me any things or anything:
Could someone explain what breakpoints are in short or whatever, just interested in general knowledge not that I could do anything with something I do not even know what it is.

You can set a breakpoint on read, write or execute to pause the game when such a case for a specific address happens. The breakpoint handler will then pause the game when it detects what reads/writes from/to an specific address and gives you a code dump on the GUI (gecko dnet side). By setting breakpoints on execute mode you can check out the values of all registers

So basically this stuff would be useful for developing cafe OS "plugins" or other processes that would interfere/work in tandem or whatever with the main OS more or less.

Thanks, might not be dev myself but do like to know this stuff.

Chadderz apparently got breakpoints working in a hacky way, and hasn't released them. dantarion was also working on it at some point, but I'm not sure how much progress he made. It's not an immediate priority for our team.

I miss the whole USB gecko setup on the Wii. Was so good finding the address you need via breakpoints and writing some asm codes to fire a function a custom button click.

Ok, thanks, may be just a matter of time.

Well, we can write asm codes but the possibilities are very limited. We need to find an instruction that's always being executed. Here's an example: https://gbatemp.net/threads/post-your-wiiu-cheat-codes-here.395443/page-43#post-5714930

This could have done the job too in helping you understand breakpoints

As we all should know, this is by far not as useful as finding the instruction that writes or reads a certain data section address

It appears as if @Dantarion never finished it but somebody should definitely put this on their todo list since it's quite a big deal for game hacking. Most of my Wii game hacks were made in assembly. It's too good and persistent by default so it plays into the hands of the current state of having no (proper) server-sided cheat injection abilities

Here's an idea: in the tcpgecko installer, you could create a thread that constantly detects each instruction the processor runs, disassembles it using DisassemblePPCOpcode(), hooks it using the "hook registers" feature that you have already created, analyses the dumped registers, and determines whether it wrote to/read a given address or not. Just a thought

Nice necrobump.

You can't do that. With C programming, you have no access to assembly instructions like this.

+ I'll add something, even if this was possible, you can't do it, since the processor would be overused, and could damage the console.
