I had this problem as well, had to go into duckstation manually and configure the controls. Click load profile and select xbox controller, then it should work from there :)

PS2 - Jak2/3 - Games don't show up on the wheel. I checked system roms and Jak 2 is there, though with a strange name at the end(USA.01) Jak 3 I could only locate the .tmp file, no 7z. Jak 2 is also present on the xml file, though Jak 3 is not, and neither show up on the wheel or when auditing in rocketlauncher. MAME - Metal Slug 4 - When playing two players, if I press Y(the action to throw grenade) as the 2nd player, it closes out of the game altogether lol. I tried remapping but it happens whatever key I map it to. Game works fine as long as that button isn't pressed for the 2nd player. Odd.
