Retropie on Pinephone
#1
Games can be launched from command line but emulationstation crashes on load (x connection broken error) and the virtual keyboard map is pretty random. Anyway, here's a blurrycam video showing it in action.

Start with the latest debphosh image and follow the below steps. See retropie website for more info.

Code:
sudo apt-get update

Code:
sudo apt-get install -y git dialog unzip xmlstarlet build-essential libpython-stdlib libpython2-stdlib libpython2.7-minimal libpython2.7-stdlib python python-minimal python-six python2 python2-minimal python2.7 python2.7-minimal

Code:
wget http://ftp.de.debian.org/debian/pool/main/p/pyudev/python-pyudev_0.21.0-1_all.deb

sudo dpkg -i ./python-pyudev_0.21.0-1_all.deb

Code:
git clone --depth=1 https://github.com/RetroPie/RetroPie-Setup.git

cd RetroPie-Setup

sudo __platform=generic-x11 ./retropie_setup.sh

You should now see the Retropie-Setup Script menu:

- select Manage Packages
- select Manage core packages
- install retroarch, emulationstation, retropiemenu, runcommand

Then install some emulator cores and game engine ports - I have tried the following:

- from Main packages:  lr-mame2003
- from Optional packages:  lr-snes9x2005, lr-pcsx-rearmed, lr-nxengine, ioquake, tyrquake

You can launch emulationstation from the desktop shortcut or the terminal:

Code:
/opt/retropie/supplementary/emulationstation/emulationstation

Alternative is to launch the retroarch menu:

Code:
/opt/retropie/emulators/retroarch/bin/retroarch

You can launch a rom and the relevant emulator core directly from the terminal:

Code:
/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-snes9x2005/snes9x2005_libretro.so /home/debian/RetroPie/roms/snes/yoshi.zip

Or for a port, locate it in the rom directory and launch the relevant script:

Code:
/home/debian/RetroPie/roms/ports/Quake.sh

If the game window is too large then you may need to install scaling support.

I've been testing out the playstation emulator and notice that disabling vsync doesn't help as much to improve fps for 3d games as compared to 2d games.

For a like-for-like comparison, I ran streetfighter alpha 3 on both mame and pcsx cores on retroarch. I guess there's more overhead on the pcsx emulator but slower paced games are playable.

sfa3 in mame 
--vsync--on ~35 fps
--vsync-off  ~70 fps

sfa3 n pcsx
--vsync-on ~25 fps
--vsync-off ~35 fps

Have you tried to pair a BT controller with the phone?

Unfortunately, I have no bluetooth joypad or keyboard at the moment.

Just playing with the various audio settings to try to reduce stutter - selecting the tinyalsa audio driver seems to help. I suspect someone more familiar with the retroarch settings could get it running pretty smooth.

As an alternative, I managed to get bluputdroid working on another phone to basically emulate a bluetooth keyboard/joypad - and yes, it connects to the pinephone and inputs are picked up by retroarch/games. Not a real substitute for hardware but it works! Big Grin

Here's another low res and poorly synced video recording: revenge of the blurrycam. I should really find a better camera but it gives you some idea of the performance to expect.

Edit: Noticed the menu icons were missing so added the assets directory to the retroarch config file

Edit 2: Cave Story works but N64 and Gamecube cores fail to load (egl_bad_match)
