change the screenmode to 640×480 by pressing m when launching the emulator.

[petrockblog]

2a is fine. You don’t have another USB power supply/charger around to test ?
did you try without the usb devices connected ?

[petrockblog]

Maybe your psu is faulty, or poor quality/knock off etc. with any sort of issue like this, the first thing is to rule out the psu. I have seen reboots before with usb devices connected when the PSU was not sufficient. Also without the usb devices, to make sure it isn’t related to them.

[petrockblog]

I thought you said you already tried that ? It’s on the main download link on the menu on this page.

[petrockblog]

which emulators specifically ? which rom folders were you using ? (there are multiple snes emulators)

[petrockblog]

try with another PSU. Also ry booting without USB device etc.

[petrockblog]

Earlier images had overlocking enabled by default (medium overclock from raspi-config). This was not ideal, as it should be left to users to decide how much they want to overclock their set up.

I guess you didn’t adjust the overclocking on the 2.5 image ?

Also – for changing video mode – just press “m” before an emulator loads – no need to edit the es_systems.cfg

[petrockblog]

Did you also change the “device_mouse” to raw again – maybe that will work too.

[petrockblog]

if you don’t get a working video mode with those settings, you might need some additional ones – refer to this post

http://www.raspberrypi.org/forums/viewtopic.php?p=290698#p290698

[petrockblog]

change to these settings in advmame.rc

device_video fb
device_keyboard raw
device_sound alsa

(ie – no more sdl) – you may need to re-add a modeline also depending.

[petrockblog]

it’s my mistake – so I apologise, as I wrote shift+escape in the instructions, and it’s ctrl+escape. I was very tired when I did this (and I am under the weather). Ill fix the wiki.

[petrockblog]

I may have to change this in the future, as currently in the menu “escape” reboots, so it could be accidentally triggered.

It’s still a lot more functional than the previous emulator we had though, and I was successfully playing turrican 2 earlier on my pi1 (overclocked).

[petrockblog]

Well, it is in the first link.. so not too hard to find :)

I’ll post it again:

https://github.com/retropie/RetroPie-Setup/wiki/Amiga-emulator-%28UAE4All%29

ctrl+escape

[petrockblog]

I will change the gui update script so it throws a more visible error on screen if the update fails.

glad it is working :)

[petrockblog]

yeh so it looks as though you must have edited a file at some point which stopped it from updating.

[petrockblog]

you can quieten output by adding “quiet” kernel line parameter. may be possible to have a fullscreen logo as soon as the kernel loads, but you would need to do some kernel hacking :) (or pi firmware hacking :) )

We wouldn’t want to include that as default, as although you may not like the boot messages, they are very useful for debugging :)

[petrockblog]

the script is not up to date. did you get an error when trying to update it ?

How are you updating it ? from the GUI ?

Please can you try from the commandline:

sudo git pull

from within the RetroPie-Setup folder.

[petrockblog]

As mentioned – please use the latest 2.5.x image and we can go from there.

[petrockblog]

The dependency for that library is included so it should have been installed.

I’m keen to know why it hasn’t worked as I’m unable to reproduce it. Just to check a couple of things.. please give me the output from

head ~/RetroPie-Setup/scriptmodules/emulators/uae4all.sh

and also please then update the script, re-run option 1 and please send me the install log which will end up in ~/RetroPie-Setup/logs/ (host it on google drive or something)

[petrockblog]

Which version of retropie are you running?

(Make sure you are running the latest 2.5.x version)

how are you powering your pi ?

(I have seen reboots like this due to power supply issues.)

have you enabled overclocking ?

(Can also cause instability depending on settings)

do you have any usb devices connected?

[petrockblog]

how did you update the binaries ? Please give me information – I have nothing to go on. You need to update the script, and then install from menu 5 – the menu to “update retropie binaries” will not suffice.

A full binaries install is actually recommended due to the amount of stuff that has changed recently.

[petrockblog]

just to check – you updated your retropie-setup script first right ? :)

I just tested on a vanilla raspbian and it worked fine, so it can’t be a dependency issue.

[petrockblog]

which shared libraries ? please drop to a console and run “/opt/retropie/emulators/uae4all/uae4all”

The new emulator works – I’ve been running it. How did you update exactly. If I can see the output on the screen I will be able to help further. It’s possible I missed a package dependency.

[petrockblog]

hehe welcome :)

[petrockblog]

all changes are done on the development site on github

https://github.com/retropie/RetroPie-Setup/commits/master shows recent commits

(it is linked in the retropie menu on this site).

(I’m user joolswills on github)

[petrockblog]

Yeh. but to be sure to get everything up to date you will probably want to delete /opt/retropie and then run the full binaries install.

[petrockblog]

the 2.5 is not optimised for the pi2. it will work. If you update the script and then binaries on it, you would get rpi2 optimised binaries. There is another image on my google drive that is optimised for the rpi2 – whether stuff is noticeably faster though is another thing.

https://drive.google.com/open?id=0B_knGioK16E6bkZ1M1VrQjZuR1E&authuser=0

note mupen64plus may need updating on it to work. There are a few other emulators too that have had changes since the image for the pi2.

I have only had my pi2 for few days, so am still working on stuff.

[petrockblog]

Hi, due to no response from upstream regarding some issues with pifba, I forked it and applied some fixes on github myself – retropie now pulls from my repo – so if you do come up with anything, feel free to post a pull request against https://github.com/joolswills/pifba

Cheers!

Also, the ControlBlock might be very interesting for you. It is intended especially for RPi Arcade Machine Projects: https://www.petrockblock.com/2014/12/29/controlblock-power-switch-and-io-for-the-raspberry-pi/

[petrockblog]

I would try another card. Also make sure you are not overclocking, and check psu/switch psu.

mupen64plus is not a retroarch emulator. I have no yet looked at the mupen64plus-libretro core.

You may be launching the wrong emulator.

[petrockblog]

I have mine.

[quote=86947]Just wanted to make a quick post to thank PetRockBlog who has very generously bought me a Pi 2 and an ODroid C1.
[/quote]

Also from me many thanks to you and everyone else in the community for the support!

[petrockblog]

please download the 2.5.0 image and try with that.

[petrockblog]

yep (make sure you update it first of course)
