I installed Ubuntu 16.04.1 64-bit , installed RetroPie via script, and everything seems just fine.
this is a different laptop than last time, but I am happy as can be.

thank you very much

@Shadowfax

Have you by chance altered the video mode, resolution, or frame buffer display settings in the run Runcommand menu?

Cheers. I think I've got it installing now. :)

Yeah it needs work. It may have been best left out tbh, but I was short on time to test, so I thought it would be ok to leave it in experimental.

To debug please choose one system (Even if the problem is on many, it's better to debug one) - and please provide all the information you can regarding version etc as mentioned in the sticky topic, so I have an idea of what version of everything you are running.

The output of dmesg and cat /var/log/syslog would also be useful - can use a site like https://paste.ubuntu.com/ for the logs

I'm sorry, I wanted to change it with another theme :-)

@nickes5

How do I do that

I have reimaged the sd card multiple times

It could be that your arcade controls aren't directly supported. What exactly are you using and have you been able to get other controls to work?

@ProxyCell perhaps they called it coleco for brevity's sake.

Anyways it's unlikely that name will be changed as its been in the core of mess for a very long time and would break things.

I named it coleco in the systems here to maintain parity with mess as advmess also uses that system name. You can still theme it by colecovision in ES even if the system is called coleco in the backend.

Related see all systems here:

I'm on version 4.0.7 and it's also under optional packages here.

@naddel81 there's no upper bound. My suggestion is to go back to the slot 1 when you reach the slot 20 (TBH I'm not sure if it will overwrite the existent states, but you should try).

The default hotkey to decrease the save slot is select+left.

And please, consider that topic renaming. ;-)

So I am silly and blind too

Thx!

Since I have no RetroPie in front of me right now...

Activate the statistics. If the Frames are not 50, you have a problem. Delete configs again, edit them manually and start Vice (without messing with configurations via thw GUI)

Speed always has be to Automatic

@TonyTheTGR
Probably yes, it's described in the Wiki:
https://github.com/retropie/retropie-setup/wiki/Dreamcast

if they are connected, they are not showing up as input devices and I saw little in dmesg. output of cat /var/log/syslog after they are connected might give more info. (Use an external site for that log - it will be big)

If you mean you can't use the "exit" hotkey when in RGUI (and the menu hotkey) - I believe so. You have to choose "quit".

Not sure if this is actually by design or not - but you can query it here - https://github.com/libretro/RetroArch

Which version of Advmame are you using in both instances?
Which game are you trying?
