Mine is blue, and I took a knife and cut out the rubber clit nub. If you do that, you can pop a PSP replacement joystick right on with zero effort, it just snaps right on! It works SO MUCH better than the rubber clit.
Also install CFW if you haven’t! I love my N3DSXL.
I followed https://3ds.hacks.guide/ and it took me the better part of a day. Maybe six hours. The the WEEK AFTER I HACKED IT (this was maybe seven years ago?) they released a MUCH EASIER HACK. it took me under an hour to hack my partner’s 3DS.
I was scared to do it because what if it went badly? But nah, snipping out the clit nub was super easy and I had a spare PSP… the PSP joystick snapped RIGHT on and suddenly I had infinitely more control over my camera in games! I was sooooo happy.
Edit: I chose to use flush cutters to chop my C-stick out, I didn’t want to take my 3DS apart. I modded my PSP by taking it apart and hot gluing cut-out NES sleeve bits to the buttons for DJ Max Portable and didn’t want to go through all that again.
Wonderful, good luck! It’s much easier and safer than it used to be. I just did it so I could back up my Monster Hunter saves, but now that the eShop is dead I’ll for sure pirate stuff if I play it more any time soon.
I also got an R4DS for regular DS games… it’s a cheap DS cart you can stick a microSD card in and load up DS roms! I think there’s a way to do it with just software on the N3DS as well, but I don’t remember. I had the R4DS from like 16 years ago (oh no I’m old) and I was happy it works on my N3DSXL as well! Lots of Osu! Tatakae! OUENDAAAAAAN! (Which I guess is a big thing with people now?!)
