    Question 1: Is there a converter? EVERYTHING the Gamecube controller has (sans rumble, one shoulder button that's never used home and select) is on the Classic Controller, even the analog triggers are on the first model Classic Controllers

    Question 2: Is it possible that once Gamecube games are up and running on WiiU (you know they will eventually) that the Classic Controller could be used (or a Gamecube controller acting as a Classic Controller)?

    Even if we could just use a converter for Wii/U software it would be incredibly useful for Smash Bros players, I've seen the one video where this guy has like 2 open circuit boards to make this happen but maybe a smaller solution is in order?

    1: No, but you may be able to benheck one together if you've got some Electrical Engineering chops.

    2: They already are under Devolution, but there's no Wiimote/CC input. The developer is working on it, however.

    Thanks a lot! More on this as it develops, I'm trying to find a converter/asking people in the know for converters.

    That is the first solid lead in a very long time, thank you.

    I built one myself and can confirm it at least works with SNES controllers (don't have a spare GC female cable to test). The only issue is that some VC titles won't detect it properly and still give you the "You need the Classic Controller" screen, but unplugging and replugging it while on that screen works. I'm currently working on a surface-mount version of the hardware to build fully inside of the SNES controller so it will look just like the Club Nintendo SFC classic controllers that sell on Ebay for $100 each.

    Now this IS nice. I've been wondering if something like this existed for a LONG time. (Thought it had to be possible but but never could fine anything like it.)

    My concern with this is I see no reviews for the store. Does the gentleman running this store have a presence here at gbatemp, or has someone ordered from him before? I just have zero soldering skills but would LOVE to have the adapter and the GC extension cable.

    I don't think he's a member here, but the hardware and software are both open source, and I'd say from the photos that the quality of work looks to be good. I've built one myself from scratch and the hardware is ridiculously simple (which is super nice). If anybody wants a converted SNES controller (i.e. internal mod resulting in something nearly identical to the official Club Nintendo controllers), I'll be selling them shortly after New Years. I might be convinced to internally mod a Gamecube controller as a commission if anyone wants one done that way. In fact, if there is enough interest, I'd be willing to build and sell kits for internal modding purposes or pre-modded versions of any of the controllers supported by WRA.

    Can you bring over the analog triggers from the GCC? It's a big deal if we ever get gamecube on WiiU going and for Project:M on WiiU.

    I haven't tried a GC controller myself, so I don't know if the device supports the analog triggers. Give me a bit and I'll dig through the source code.

    The code doesn't currently support the analog trigger data for the classic controller, period. It wouldn't be too hard to add it on the Wiimote side, but the GC code seems to be quite fine-tuned timing-wise. The GC read function has a lot of inline asm for timing purposes, and I don't understand the protocol well enough to understand the timing hackery going on. If somebody with the relevant understanding of the GC controller protocol wants to help me out, I'd be willing to give it a shot.

    Ok, so looking into it more, I'm pretty sure that the WRA is reading the full GC data struct into memory, so it might be incredibly simple to add the analog triggers. Somebody correct me if I'm wrong, but of the supported controllers, the GC is the only one with analog triggers, right?


    Code:
    NES
    SNES
    N64
    GameCube
    PSX/PS2
    Neo Geo CD
    Sega Saturn
    I don't have a GC cable to test, but maybe I can get my hands on one at GameStop soon...

    the adapter states that it supports PS1/PS2 controllers, that means DualShock 1 and 2.
    The DualShock 2 is (here is a c&p from Wikipedia including the cite link (the 5 at the end)

    Ok, I'll look into the feasibility of PS2 analog triggers. I just ordered extension cables for NES, N64, GameCube, and PS2, and I own controllers for all of those consoles, so I'll be able to test stuff in a couple of weeks.

    Ok, so I'm going to say that Gamecube is possible but after looking into PS2, I don't know there. First of all, it's ugly. Second of all, the analog control for the PS2 triggers isn't going to match nicely with the CC and GC anyway, in a physical sense. The CC and GC both have quite long "trigger pulls" for their analog, whereas the pull on the PS2 triggers are almost nonexistant (which is why they call it pressure sensitive). So I will definitely put the effort in to try to add GC analog triggers, but I probably won't even bother with them on PS2.
