Have 2 ROMs, recognized, but won't run

JohnAndGary

Hi, I set up my son's Xmas Retropie (Vilros), and he set up the controllers (he's 10). He's had Pi's before so I installed lxde. This is running on a Pi4. Using Raspbian desktop, I copied ROMs (just the .SMC files) to /home/pi/Retropie/<subfolder>. (Not sitting at the system in question right now, but I'm sure it was the right subfolder.) I got to where Retropie showed the selection for SNES and selected and it showed the 2 games (Pacman and Pong), then turned it over to my son. He found the Launch menu item. Pong started but wouldn't work; Pacman wouldn't start. I have googled extensively, though by now my google-muscle may be fatigued after everything else to get this far. My understanding is the Core association and access should be automatic, but maybe that's not so? I appreciate your help in what I'm sure is a busy time!```

Please remove the links to ROMs, posting links to copyrighted material is against the forum rules.

@johnandgary Often running the game with verbose logging enabled will reveal the problem. Open up the runcommand menu when prompted after trying to start each game: https://retropie.org.uk/docs/Runcommand/

If it's not obvious from the log then post it here for more eyes :)

Correction: Pong does run. Pacman just returns to game selection menu.

found this in runcommand.log:

modprobe: FATAL: Module g2d_23 not found in directory /lib/modules/5.4.72-v71+

I googled that (Module g2d_23 not found in directory /lib/modules) but not yet making sense of those results.

You should share the whole of your verbose log here.

Maybe that message [on its own] is not as important as it seems - according to this thread, that module is not expected to be found on a Raspberry Pi: https://www.raspberrypi.org/forums/viewtopic.php?p=494884

@busywait

This image is what I have now.

Given the problem seems specific to one game, I think I should close this and see if I can get further on my own, do you think so?

@mitu BTW Zophar's says "Super Nintendo Public Domain ROMs" -- do they lie?

On the Pi, RetroPie is meant to be run outside the desktop environment. You should start EmulationStation from a terminal, after exiting the RasPi desktop.

Even if they are right, links to ROM sites are agains the forum rules.

@mitu Right, we are doing a reboot from lxde after any changes and then it boots to Retropie. Under Ports it shows DESKTOP as a "game". That all seems to be working well.

I was hoping we could connect to our wifi from the Raspbian desktop. We did once and then it stopped working.

WiFi seems fair game for a separate post - but before then, did you find the docs, and the page about setting up Wifi inside RetroPie? https://retropie.org.uk/docs/Wifi/

I see, so the log (/dev/shm/runcommand.log) is actually taken after starting the destkop. The log file is overwritten when you start a program/game from EmulationStation, so the emulator's log is no longer available after you start the desktop.

What emulator is started for the SNES games ? The name should be shown when the game is started, in the runcommand launch menu

I think first time posts can be changed for 30 min after posting it, otherwise you'll need some reputation points to be able to edit it.

@mitu Ok, I can access log files from Retropie's file browser, just more comfortable with Raspbian but I can learn :-)

The runcommand docs page looks very helpful; I bookmarked that. If the TOC had said "Launching Games" instead of "Runcommand" I might have looked there :-)
