options for removing dithering, increasing internal res etc are in https://retropie.org.uk/docs/RetroArch-Core-Options/

you can also do something similar in pcsx_rearmed via
https://retropie.org.uk/docs/Playstation-1/#video-double-internal-resolution
and

I think I figured out my mistake. Since I was using an Xbox controller I was using the optional Xbox Driver. I uninstalled this and now everything works great. Thanks for taking a look!

@g30ff thanks!!!!

Ok, after some more digging around in the menu, it’s just a simple error in the documentation.

The correct path is: Quick Menu > Options > Pad # Type

@dankcushions I think that's half the battle, the retroarch approach to mame inputs gets very confusing for users since there's no one size fits all solution. I find many users get lost in all the menus, saves, opt files, etc which are tangled with the inputs mame is expecting.

Thank you for clarifying and defining the difference. I thought I was going mad, because no matter which menu I was going in, I could not find the ''override option'' anywhere. Was I using a different software? So I just assumed it was the remap option which obviously wasn't working and I can understand why.

After some searching, I realized that a bunch of options including ''overrides" where switched off, not to be visible. So I just tested what you mentioned before and it worked! Now I can use the arcade sticks, even for beat'em ups and shoot 'em ups on consoles, (game override). Thank you so much!

a piece of the conquest image is missing. The game is properly centered so I can't touch it.!

This info is covered already in the Docs - including where to copy the BIOS files, since RetroPie already configures RetroArch.
Note that some games have issues when the 'boot to BIOS' option is selected in lr-pcsx-rearmed.

only 0 and 1 are registering in your config log file. If your happy using advanced mame just use that. I find stand alone emulators more pleasing to use as well :).

In my case, it was because I registered the PS3 dualshok controls, using the xbox360 driver ... In emulationstation it works ... But in RetroArch it does not.
The solution was: uninstall the xbox360 driver and re-activate the ps3 dualshock official driver, when rebooting ... Resigne the buttons in emulationstation, I recognized as ps3 dualshock command and I work the retroarch controls in all the emulators.

There is a new input mapping screen starting with RetroArch 1.7.2 - https://forums.libretro.com/t/new-input-remapping-menu/15584 - and as a consequence the previous re-mapping files are not working. I think that's what you're experiencing. Can you give more details about your system - as requested in https://retropie.org.uk/forum/topic/3/read-this-first ?

Glad to hear that! I find your hardware setup very clear and logical. So far, I did not find anything on the driver site.
You mean it was an issue with a configuration file of RetroArch, right?

@phantomthrill What's the RetroArch version you're speaking of ? What's the problem you were having ?
RetroArch uses the A and B buttons to navigate in the RGUI - that's the default and it matches the Emulationstation way of navigation/selection.

@hank-scorpio

How do you have the controls attached to your Pi, are they connected directly to the gpio or is there a usb interface of some description?

Also, you should check out the read this first link at the top of the forum pages (https://retropie.org.uk/forum/topic/3/read-this-first) and complete the information requested in there in your post.

@w44dde your issue is pretty common, check your wires on the joystick. I bet you have the wires connected "upside down" on one of the joysticks. Simple fix should be just to switch the wires connected to the joystick for player 2.
