DOSBox and RetroPie.

All attempts to log, end up failing. Could the problems be permission errors? If so, what should they be set to? I tried setting /usr/bin/dosbox to setuid root, no luck.

Could be, but it's not what you're trying to do. If it's a permission issue, it's more likely the other way around - you've made some files root owned and the pi user cannot write over them.

And I cannot use DOSBox from a SSH (if I could get it working) connection.

That's normal, I don't see how that would work out of the box - the SSH connection is a text stream, it's doesn't have a display attached.

Please attach the log file I mentioned and also add more info about your system, as requested in https://retropie.org.uk/forum/topic/3/read-this-first.

Here's some info. I apologize I cannot provide more in depth details about the error messages received,
I cannot seem to be able to acquire them. I turned on "debugging" in the dosbox.conf, but no luck.

Pi Model or other hardware: Raspberry Pi Zero
Power Supply used: Unknown
RetroPie Version Used: 4.4
Built From: Pre made SD Image on RetroPie website
USB Devices connected: n/a
Controller used: n/a
Error messages received: ???
Log found in /dev/shm/runcommand.log: Unavailable
Guide used: (Mention if you followed a guide): None
File: (File with issue - with FULL path): n/a
Emulator: SNES emulator (not sure which one RetroPie uses).
Attachment of config files: (PLEASE USE PASTEBIN.COM FOR LARGE LOGS): n/a
How to replicate the problem: n/a

Any way you could share your dosbox.conf file? I believe, that's where the problem is.

Thanks.

I don't think so.

Attachment of config files: (PLEASE USE PASTEBIN.COM FOR LARGE LOGS):

You should at least have a /dev/shm/runcommand.log file present after you're trying to launch a game through Doxbox.

I doubt it, I have the 'stock' configuration file that comes after you install RetroPie's dosbox package.

What game are yo trying to run ?

[ignatius]

Bleh. Brain fart. I don't know I said "SNES emulator".... Anyway, there is no trace of a /dev/shm/runcommand.log Is there anyway I could open up a terminal on the Raspberry Pi and run DOSBox manually? I have a menu entry that appears to be DOSBox.. but, none of the games launch (to answer your question, i'm trying out "Master Of Magic") for some reason. I even made a shell script to launch dosbox, no luck there either.

@ignatius Sure, doxbox is located in /opt/retropie/emulators/dosbox/bin/dosbox, just run the command from the terminal and see what errors you get.

[ignatius]

Hmm. No sign of it in that directory. And for some reason, unknown by me, I cannot install DOSBox from "RetroPie Setup", it does not have a binary to download. I can only install from source, and even then, it doesn't work. Not sure if it's my /etc/apt/sources.list or what. Something I should mention, is that, I installed dosbox via "apt-get install dosbox".

Thanks.

Dosbox is not installed via apt. The package should be in the optional packages section:

Something I should mention, is that, I installed dosbox via "apt-get install dosbox".

That's why you probably didn't have the es_systems.cfg configured and the Runcommand doesn't work.

[ignatius]

Ok. Trying to "Install from source"... We'll see.

[mitu]

@ignatius All optional packages should have a binary update/install option - don't you have that option ?

[ignatius]

No, I don't. :(

[edmaul69]

@ignatius usually if you dont have a binary it means you arent connected to the internet. But you havent said if the source was installing. Which dosbox are you installing?

[ignatius]

I've tried two different WiFi Servers. No luck with either.

[ignatius]

Could it possibly be a permissions error?

[edmaul69]

@ignatius have you tried clicking on update retropie-setup? What happens? 2 things i have seen are biggest issues. No wifi or your clock settings are wrong.

[ignatius]

Ok. I sovled it. It turned out that my router was blocking my RPi. Thanks to everyone for their insight.

[ignatius]

Now, one last question before I close this thread. I'm trying to transfer my RPi instalation from a 16GB card to a 32GB card. I formatted just as I did my 16GB card, partitioned the same, etc, but it just isn't working. I know that the RPi requires that the first partition needs to be FAT32 formatted, and the second partition needs to be formatted ext4 Linux. I copied my installation over, but it just isn't booting. Does the RPi Zero W not support 32GB cards, or what?

Thanks to everyone.

@ignatius You can just create a backup image from your existing SD card, then write it - with Etcher/Win32Diskimager - on your new SD card. It should work as long as the Pi model is the same.
Afterwards, you can go into raspi-config (which you can start from the RetroPie menu) and use the Expand filesystem option to fill up the rest of your 32Gb card.

[ignatius]

Awesome. Thank you. :)
