    Thanks. :)

    The update usually takes about 2 seconds.

    Can you please open up CMD in the same directory as JGecko U (e.g. via SHIFT right-click and "open command prompt here") and type
    Code:
    java -jar "JGecko U.jar"
    to run it from the command line? Then in JGecko U just do another update and see if there is stuff being printed on CMD because right now it keep trying infinitely when there is an error which could be the case here. There won't be a usual stack trace error message.

    This is like the 3 guy from the US with this problem but it it works perfectly for me and almost everyone in general, strange.

    EDIT:
    I just changed that, please re-download and see what happens.

    Completely my pleasure!:)

    Now I'm getting the following error message on start up and when clicking the update game titles button. It's also the same error I got when running the previous version via CMD.

    Thanks.

    I made another new version which outputs the titles.html file when you update the titles. Please send that file here but zip it first if GBATemp complains about unsupported file types. This will let me see what's wrong.

    Hello everyone I'm sorry to ask this question. I've read A LOT of the discussions, questions, guides, videos, etc. I'm kinda confused with their being different guides and which one is the most updated. My question is what do I next to use JGecko U. I have haxchi on my Wii U (5.5.2). I've downloaded the current JGeckoU to my computer as well updated my Java. What more do I need to do? I was trying to figure out to which site(s) I had to visit or something before running the TCP Gecko app (via homebrew)

    I'm guessing you can't connect while inside the game either? I'm having that problem right now

    I'm using the latest TCP Gecko installer and the latest version of JGecko U and I'm launching TCP Gecko without SD card support. Afterwards, I can connect to my Wii U just fine as long as I'm still in the home menu but as soon as I'm in the game, the connection drops, can anyone help me there?

    @BullyWiiPlaza I've tested every version of tcpgecko.elf from GitHub commit and they all give the following error when trying to connect to Twilight Princess HD. I've also tried the trainer and it doesn't connect either. Plus, I've tried several other games and they all connect just fine and I'm able to send codes.

    Can someone answer my question too?

    UPDATE: Nevermind. I got it. Hooray for me!!! But I do have another question. Can this be used to hack digital downloads of Gameboy Advanced games? I want to hack my digital download of Golden Sun and Golden Sun: The Lost Age

    If you don't mind me asking, on which firmware version are you? Are you playing the game from disc? I'm on 5.5.1 and I'm playing the game from disc, I'd just like to find out some common denominators. I've just been looking forward to playing that game with cheats so much that I'm kind of desperate now :D The fact that this issue has apparently persisted since November so I'm kinda worried

    I'm on 5.5.1 as well, playing from USB HDD. The thing I find strange is that according to what I've read it use to connect, but I've tried every version of tcpgecko.elf from the GitHub commit page dating back to Feb. 27th 2017 and had absolutely no luck. I even tried an older version of JGecko U, but no dice.

    I'm on 5.5.2 now and I've tried it both on disc and HDD versions. Seems to affect everyone then. I've also tried various versions of JGecko U and tcpgecko.elf as well as codehandler.bin. This is really weird.

    I had an idea.. What else is new right?

    And I sort of just want your opinion on this, im not really asking for it to happen.

    What if we rewrote TCPgecko to perform the searching locally on the wii u?

    Surely it would be faster to skip having to dump everything to the computer first before evaluating based on the search criteria? Even if the wii u is much more slower at evaluating than the average PC, the fact that the wii u doesnt have to send the data first might increase search times.

    Just a thought.

    Is it possible to change the memory area where TCPGecko gets installed to something like 0x48000000? Because I guess if it is installed back there most other codes won't get shifted around and you can probably use addresses you found with Cemu.

    Not quite, the Wii U doesn't have enough RAM to analyze the results of its own RAM dumps and it would be an immense effort to implement. Even in Java it was painful and this is C on the Wii U. <_<
    No, it has to be executable memory anyway. Also, some games use the memory area (possibly).

    has the 'cheats on sd card' method changed or improved and made easier?
    because when it came out it was a bit tricky.
    thanks :)
