Hacking JGecko U Setup Guide

[revdirty]

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

Why is not there a homebrew that does not need a PC?

Has anyone been able to connect JGecko U and the new codehandler to Paper Mario Color Splash? I am using JGecko U 7 days old, codehandler.bin 14 days old, and tcpgecko.elf 21 days old. For some reason I Paper Mario always crashes with blacked out and garbled screen, upon connect. I have tried ticking and unticking automatically detect and ticking and unticking Memory Address Protection, to no avail.

I can connect other games without issue. Just Paper Mario Color Splash is the only game that I can't seem to keep it from crashing upon connect.

Awesome. I have found another solution for this. I just launched a game that works with JGecko U, connected to it, exited the game and launched the one that always froze (Little Inferno). Then reconnecting didn't freeze

Has anyone else had this problem when trying to download the code database?

You have to connect to a game first.

Ah ok thank you

other games lock up on me just by clicking TCPgecko.elf then running game. nothing to do with jgeckup program. ex. amazing spider man says TCP Gecko stack allocation failed on the tv

That's pretty bad lol. It won't work then because it needs this to succeed

When I select "Add Dump Registers Hook", I get this error:

What gives???
Yes, it was for any instruction, even lwz's.

Oh, okay. Weird, it will be fixed
Can you give the address used please?

No addresses work for me, they all give this error

Cool. Doesn't give me black with garbled screen, however got the "Kernel copy Thread stack allocation failed", I guess similar to what @jbuck1975 error on tv.
Tried @CosmoCortney solution and it surprisingly worked.
EDIT:
Should mentioned that I unticked "Find Memory Bounds".
Just in case if anyone is interested. Here is the memory bounds for Paper Mario Color Splash obtained from a much older JGecko U, tcpgecko and codehandler

CNFE
0E3FFFFF - 0FFFFFFF
10000000 - 4E39FFFF

It's supposed to be an assembly address, you misunderstood.
