SNAC issue with NES core

Unread post by orange428 »

Hi, I'm trying to troubleshoot an issue with my original OEM NES-004 controller with a SNAC adapter. It used to work fine but recently stopped working. I tried the controller in a real NES (NES-001) and it works fine, so the controller works on real hardware.

Some history.

I bought a SNAC adapter and the NES adapter maybe a year ago. It worked fine and didn't have any issues with it using the NES core.

I didn't use it for a while but eventually wanted to play some NES games so I hooked it all back up. I updated all the MiSTer software and the NES core. This time the controller didn't work with the SNAC.

I tried going back to the earlier versions but it didn't help. I tried to reset the NES settings, swap joysticks setting, made sure multitap/zapper was disabled, enable/reenable the SNAC. Save settings and reboot the core. Nothing helps.

I also tried different USB cabling as the SNAC adapter came with a short right-angle USB extension cable to reduce the strain on the USB port on the IO board. In the past I had the USB cable plugged directly into the IO board and the SNAC and NES adapter plugged into that. I've tried plugging the SNAC/NES into the IO board directly and not using an extension cable.

I ended up buying another SNAC and NES adapter from a different vendor. Same results.

I have a NES MAX (NES-027) controller that works fine on the SNAC. So I know the SNAC/NES adapters work. It just stopped working with my NES-004 controller.

I'm just confused as it used to work fine and it still works on real NES hardware.

I also took the controller apart and cleaned the PCB board and all the innards. Still doesn't work on either SNAC. Still works fine on a real NES.

Any ideas before I just buy another NES-004 controller?

Thanks!

i had a similar issue with a SNES controller.
i still have my 2 original SNES controllers from my first SNES console, and only one of the controllers works with the MiSTer via SNAC.
i tried everything you could think of, viewtopic.php?t=2114, but ultimately just bought a SFC controller off ebay, and it works fine with the MiSTer.

so, apparently the MiSTer is picky about what controllers you can use with SNAC.
(or, the SNAC firmware needs to be updated to handle a wider range of tolerance)
i have a set of NES/SNES/genesis/Atari adapters that work fine via SNAC with OEM controllers, but 1 of my original SNES controllers just does not work with SNAC.

to add to the confusion and point again to the SNAC firmware needing an update -

my same SNES controller that doesnt work via SNAC on the MiSTer, works just fine with a daemonbite adapter on the MiSTer.
so, yeaahh, not sure whats going on with the MiSTer and SNAC. some OEM controllers work and others dont.

It's definitely finicky. With the NES core, I've only been able to get one of my zappers to work and NES Advantage stick. None of the 5 OG controllers will work correctly on it.

As for SNES, I haven't had much issue outside of getting the Super Scope to work. I went through three receivers and two Scopes before I got a working combo. As for controllers, I finally got the 2.4ghz 8Bitdo controllers. So, those are now my mains. I was fortunate to have an OG SNES Console to test some of the hardware on. And, the Super Scope receivers were just as finicky.

Hi, thanks for the replies. I agree it must just be really nit-picky. I think I'm going to get a Raphnet USB adapter for NES and see how that goes.

So, I got the 8bito 2.4ghz NES Controllers in the other day. They work wonderfully via SNAC. I'm still waiting for the Daemonbyte adapters to show back up for sale (I'd make my own...but I like the housing he provides.) to just use them all via USB Fast Polling. As I do primarily just use the SNAC for Gun Games.

I had been periodically visiting the daemonbite shop, but I do not think it will be restocked any time soon. I would love to be wrong, though.

Looks like Retro Frog is getting into daemonbite compatible adapters.
