Sorry for bumping this tread after over a month, but I'm not sure where to ask in general, so forgive me if I sound a bit green.
While I was in agreement with everyone else here, praising the Mayflash Adapter for all it's worth, it has finally come to the point where, for me, it works on a good chunk of games in both DInput and XInput mode (TitS, MGR, the YS games). But for several others that I'd also like to play and own (SA2, NiGHTS, Jet Set Radio, DS2:SotFS) have completely stopped working altogether, even though they worked in the past.
There would be an occasion where I would restart my computer, boot up one of those games and it'll work...for a couple of minutes.
In DSII, I can get load my character's save file up before the controls stop working altogether after loading the area I started in.
In SA2, the controls would stop working at random moments, saying that I've plugged in a different controller and asking me to restart the game, even though I can't since the controls are disabled when that message occurs.
At this point, I'm sorry for the long rant, but I'm sure you guys can tell I'm at the end of my rope with this. I've looked online, and NO ONE seems to be having ANY issues whatsoever. So, is it just me?
I've already updated the driver, which didn't do anything and I doubt it's my computer, considering I brought it at the beginning of the year. At this point, I'm not sure what to do anymore, as I've tried uninstalling and reinstalling it, updating it, and trying all those third-party methods, as well.
ANY help would do at all! Please and thank you!
EDIT (4/30): I finally figured out what was wrong and why those games weren't working with the adapter.

Apparently it was because of the NVIDIA Streamer Service for NVIDIA SHIELD, which disables any input used by anything using XInput for those certain games, from what I can tell so you can use NVIDIA's own controller/portable device, which I DON'T own. (I own a NVIDIA Geforce GTX 970M laptop, for clarification.)
I've disabled it and now all the games that didn't work before, works and I am SO FREAKING HAPPY despite all the frustration I went through trying to figure this out.
