wimpysworld / retro-home Goto Github PK

The GNOME Flashback session is no longer available when retro-home is built using Ubuntu 22.04 and manual login to the Ludo session fails.

Might require that the ALSA compatibility fix is dropped from cmdline.txt.

Might require a redistribution agreement from Vivaldi.

Migrate the build to use Ubuntu 22.04.

I tried to run upgrade in desktop mode just to se if it's works and it was missing mkimage for creating firmware image.

Installing u-boot-tools solved the issue. I started this as an issue as I am not sure if upgrading firmware is in scope at the moment

Integrate deb-get so Ludo, and possibly Vivaldi, can be installed/updated easily.

Steamlink tested and only worked with two modification. gpu_mem had to be set 256MB at least, and had to install https://packages.debian.org/sid/libjpeg62-turbo otherwise the image would be laggy and would hang after a while.

Tested it on LAN with 90MBit/s available bandwidth and 720p playable with some minor ugliness and delay.

Drop all legacy themes from the build.

I did a fresh install, and then told it to load the SNES core, the NES core, then the Genesis core, and as soon as I click it will crash directly to the login screen.

Use systemd to initialise swap using zswap.

I have use jellyfin before and they have great workaround for rpi4 hw acceleration and this project is a really good example of cross compiling stuff for the rpi. https://github.com/jellyfin/jellyfin-ffmpeg

See https://deskpi.com/products/deskpi-pro-for-raspberry-pi-4

I have try to test the basic rpi4 image burned it started up ludo starts with smaller grey square in the left top corner nothing else. Desktop mode works fine

Gamepad seems like a no issue it's somekind of usb HID device by the look of it as I couldn't find other than "it's just works"

1. I look trough and if dpi24.dto has no custom patch made by retroflag it's out dated. The latest file can be found

https://github.com/raspberrypi/firmware/blob/master/boot/overlays/dpi24.dtbo

LCD specific config.txt available in patch zip from their repo. That can be easily copied.
2. case has only a power switch and that can be implemented with simple

from gpiozero import Buttons, LED


powerPin = 26
powerenPin = 27

def shut() :
    os.system("sudo shutdown -h now")

#Turn on power led
led_power = LED(powerenPin)
led_power.on()
#init shutdown feature
btn_power = Button(powerPin)
btn_power.when_pressed = shut

3. The real issue is to switch from lcd to hdmi. This should be done by rebooting, and the gpicase2 has a weird check for it
   The pin has to be enable as input and this method seems to be working only with this case. same issue with audio

HDMI_HPD=18
HDMI_HPD_VALUE=$(cat /sys/class/gpio/gpio$HDMI_HPD/value)

if "1" = $HDMI_HPD_VALUE ; then

4. internal audio is simply adding /etc/modprobe.d/alsa-base.conf (maybe to cmdline.txt instead)

options snd_usb_audio index=0

However switching to hdmi audio from internal can be tricky
