Are these adapters any good?

I am seeing this design of adapter more and more and was curious about it

https://www.amazon.ca/dp/B0BLSQRD4S/

I see them claiming to be compatible with a bunch of things like the ntt data pad, can anybody confirm if these are actually quality?

Also, I saw no mention of paddle support for the atari side, does anybody know if they are or aren't?

Those are running through the USB system, so there will be at least a couple milliseconds of delay before the signal gets from Linux to the FPGA. The SNAC adapters are effectively zero latency. In practice, however, 2ms of latency will not matter at all. Plus, you can't use SNAC controllers with the main menu system; they only speak to relevant cores.

Because the adapters route via USB, you should be able to control not only the menu, but also other cores, as long as you have enough buttons. You can also probably connect more than one at a time. SNAC adapters have to be swapped for each core, which is a pain.

If those work as advertised (and assuming I'm understanding the broken English correctly), they look like a good solution.

I'd heard about Daemonbite adapters, but had never looked them up before. Now that I've found them to refer you, I'm realizing they're similar enough that the ones you're linking here might be copies. The Daemonbite person publishes their schematics, so these might literally be the same thing.

Official Daemonbites are a little more expensive, but come with enclosures, which I think would be an important usability feature.

The schematics are here:

and there's a link in the readme to take you to the Daemonbite store.

Dunno nothin' about Atari paddles, sorry. I'm sure they would work with SNAC, but I dunno about USB adapters.

I know Daptor 2600 D9 is pretty good for a similar price. It has a comprehensive list of exactly what sorts of controllers it supports, including Atari paddles and ST/Amiga mouses. Its also been tested for very low lag (under 2 ms) on Mister.

Those will be based on Mike's Daemonbite code which is very low latency at around 0.74ms and work very very well

There is no noticeable latency on MiSTer using USB controllers, most testing we see doesn't factor in frame intervals or polling rates for example

SNAC was not designed for standard controllers and is limited to mostly one player with no OSD control. Not all cores even have SNAC support. You also need the original controller and adaptor per system it really is not worth it

Micks code is open source so you can make your own easily with an arduino

There is also a project using Raspberry Pi Picos now which will be even cheaper

As for paddles there is yet another project that uses a rotary encoder and a Arduino but not all cores have support

Since they are made/shipped from China, I'd expect there to be a good chance they are crap and won't work properly
