Thanks guys! This worked for me as well.
I don't update regularly, but once I did, I found same issue with my Multitap settings set to "auto", leaving my Castlevania Symphony of the Night quest on hold till I figured it out :)
After spending the weekend thinking about which procedure was done wrong, I remembered that I performed many installations and updates hoping to fix the problem, so I downloaded a clean .img and installed it again. After reinstalling the OS the control worked correctly, thank you anyway.
After going through all the PSX RetroArch settings I figured out my problem. To change the controller to Analog you used to go to Quick Menu>Controls and set User 1 Device Type to RetroPad w/Analog. After the update, you put that back as Retropad (without the analog) as default, go to Quick Menu>Options and change Pad 1 Type to Dualshock there. Maybe this will help someone with that problem in the future.
ohh, I didn't knew descent supported that rare analog pad.
I poked around and managed to add the option to use that analog pad in the menu, it works wonders.
I just created a pull request with the fix. now it should be a matter of time for the option appear if they accept my fix.
Well, i must say, i suddenly found a solution that works for now.
The analog stick is working, D-pad still no response.
Anyway, i changed the controller settings but did not change the up, down, left right. Just left it as the default values.
UP : up
I only have changed the buttons. this setting seems to work.
So i tested the remote on some snes games and the shoulder buttons worked. I also have been able to play some ps1 games also. Not sure whats going on but it didnt work this well last time i messed with it nor did the graphics look as good and i hadn't messed with it since i encountered the issue about a month back.
