So finally the PCBs have arrived. I tested one to verify if they work and they do.
I'll be able to start selling these starting next week. The GC version can also be ordered from now on. You can send me a PM, if you want one. Because I'm using a case and some other components the price will be a little higher than before, to cover for these and shipping rate, but it really won't be that much higher.
Also, I have not been able to test my firmware with a Hori Pad, since I don't have one. If it doesn't work correctly I'll try to fix this. You can easily update this newest version of the adapter with a programmer you can get for a few bucks from eBay. Also, the GC version's firmware isn't final yet. I still want to add stuff like settings for more sensitive L and R triggers, like on the Gamecube version.
I'll probably make a webpage that centralizes most info about the adapter. This topic has grown quite large.
Is there any sort of patch or program for the VC to make the controls less sensitive?
There isn't. If anyone has some guidelines (hex editing the WAD, don't even know if that is possible) of how to do this, if possible at all, I'd be very interested.
