@paradadf I have no idea how, but I just kept trying to launch the games hoping for the best and after about the 20th time now it works all of the sudden.

@paradadf Yeah, I made sure all of the roms are unzipped.

I'm pretty new to raspberry pi/recalbox, so I'm probably doing something wrong, but I can't get N64 games to play. I had no issue with other NES, SNES, or Sega Genesis, but when I try to start an N64 game, it briefly brings me to a black screen and then backs out to the games list. I tried looking at other peoples posts and tried to troubleshoot based off those recommendations but nothing seems to work. So far I've tried following the instructions at https://github.com/recalbox/recalbox-os/wiki/N64-%3A-return-to-ES-(EN). I ran the commands listed there and then ended up changing the recalbox.conf file by switching the n64 emulator setting from the default DMT 4 HDMI to n64.videomode=CEA 1 HDMI. Other suggestions mentioned making sure the controller settings had an L and R configured. It's basically the same as an original N64 Controller, except it connects with USB so I don't think that'd be the issue. Just in case, I went into the controller config and made sure. Still no luck.

I'm not sure what all information is useful in troubleshooting this, so here's what I have:
Pi Version:
Raspberry Pi 3 (RPi3) Model B Quad-Core 1.2 GHz 1 GB RAM

Controller:
N64 USB Controller

Output from the commands I ran on the Github link above:

tvservice -m DMT
