Hacking JGecko U Setup Guide

[SirNapkin1334]

The J stands for Java. It's the programming language this is written in.

Ohhhhh. That's what it means. And that's what the J in JNUS means.

Gekko was also the name of the PPC microprocessor that was in the nintendo Gamecube.

Awesome! I noticed once when trying to load one of my saved searches, I got a NoSuchFileException.

But if you are going to fix something.... Maybe you would consider adding a "refresh results" button in the Search Tab.

Both done now

Hey can u look into why the legend of zelda - twilight princess HD will not connect to JGecko U anymore? I don't know what version of tcpgecko that was on my WII U before but I update it and the JGecko U on my pc. Now I can't connect to twilight princess HD. I've try both the disk version and the version I copied to my USB. I've tried using both the normal built-in code handler and the new SD card cheats. None connect, all other games will work fine so far.

@BullyWiiPlaza When Editing a code, could you add a check to see if there is currently a window already opened for editing that current code? And if there is already a window opened, move the window into 'Focus' or move it to the foreground instead of opening a second editing window.

Also, could you take a look at the way editing multiple codes is handled? If you open up 2 or more codes to edit, even just so you can view them. If you do not close them in the same order that you opened them, it will overwrite the other codes with the first code you opened it seems like.

I do not know how you have it programmed, but maybe assigning every code an ID of some sort would be a good idea, and then have each 'Edit code' window only associate with that codes ID somehow.

Forgive me if my idea doesnt work with the way you have it written. When I bring up an issue, I try to at least provide 'what causes the problem' and potentially a solution.... so i dont end up just posting a generic "Youre Prgrm iss borken!!! You madee my game Crashed!" sort of message for you to shake your head at.

True, it happened to me also once. Quite odd. I will investigate this therefore.

This was handled by updating the selected row so you could open the edit dialog, select another row and then press OK to overwrite another code. Now this saves the row index beforehand and you cannot open more than 1 edit dialog also because it would eventually glitch by duplicating the checkbox and code title without actually messing up the code list. Anyway, now things are idiot-proof hopefully (not saying that you're one but for all cases).

i get this each time :/

So, I'm getting the "No Code Handler Installed!" error. I'm using 5.5.2 of the Wii U. What am I doing wrong? Here's the error message.

And when I try to send codes to the Wii U, this comes up:

Everything else seems to work fine, such as the search function and the memory searcher.

 

[Sm4shModder]

Whenever I try using TCP Gecko with Smash Bros. it crashes. It only crashes for Smash, everything else works perfectly. If anyone else has suffered this same problem solutions would be appreciated.

Try updating TCPGecko?

 

[TheWord21]

Try updating TCPGecko?

Already tried it, dude. Manual installation, Gecko updater, everything.

Also tried deleting the config file? This probably won't help but a setting in there could be corrupted

Problem: Smash Bros doesn't work for TCP Gecko

Solution: If any of you know how to fix this issue, please do tell.

 

[BullyWiiPlaza]

Problem: Smash Bros doesn't work for TCP Gecko

Don't enable SD codes to avoid crashing the game on load. Besides, only JGecko U is supported properly if you use my TCP Gecko Installer version.

So, I'm getting the "No Code Handler Installed!" error. I'm using 5.5.2 of the Wii U. What am I doing wrong? Here's the error message.

This only happens if you don't use the correct files. Read the top post and use those exactly.

 

[Sm4shModder]

Don't enable SD codes.

Why don't SD Cheats work? Is it perhaps related to Wifi, or is it a glitch?

A glitch, it seems like it's broken for some games only.

Tried that, too. I know I'm doing everything right, like the Stupiidhax exploit, loading TCPGecko from homebrew...
