Announcing Pegasus Frontend

@fluffypillow Would it be possible to add an option to ignore subfolders for certain systems?
Then a folder layout like this would be possible without the need to enter the subfolders:

/system
 /game1
  game1.zip (or whatever rom extension)
  game1.xml (contains the basic metadata for that particular game)
  boxart.jpg
  thumb.jpg
  logo.png
  video.mp4
/game2
  game2.zip
  game2.xml
  boxart.jpg
  thumb.jpg
  logo.png
  video.mp4

Again, this is an available option in Kodi when you link an movie folder to your database. I currently don't want that for any paths, just to hide subfolders for certain systems (if they are not declared in the gamelist).
Since I currently don't know how gamelists are created by Pegasus, I use ES as example to make one. That's why I want to have the xml files in the rom folder so that they can be combined by a script or directly with Pegasus (whatever is possible) . So whenever you remove/add a game by adding its folder you can re-run the script to rebuild/clean the gamelist. Only downside would be to loose information for lastplayed and playcount (but I personally don't care for those anyway).

A simple xml would then look like this:


	<game>
		<path>./game1/game1.zip</path>
		<name>game1</name>
		<desc>game1 description</desc>
		<image>./game1/folder.jpg</image>
		<marquee>./game1/logo.png</marquee>
		<video>./game1/video.mp4</video>
		<thumbnail>./game1/game1.jpg</thumbnail>
		<rating>0</rating>
		<releasedate>19910101T000000</releasedate>
		<developer>someone</developer>
		<publisher>someone else</publisher>
		<genre>pewpew</genre>
	</game>

Setting up new files would then require only to change the paths and the file name of the rom.

This it a suggestion for easier game management and not necessarily for media paths.

@ectoone So if I understand correctly, you'd like to keep the one game = one directory setup, and generate the gamelist-equivalent for Pegasus with a script, right? This is possible; first you'd create a collections.txt file under /system/ (in your example above):

collection: My Games
extension: zip
launch: myemulator "{file.path}"

Then you'd have a metadata.txt (or whatever you'd like to call it) in each of your game directories, like this:

file: $CWD/game1.zip
title: Game 1
description: The #1 of Games
assets.boxFront: $CWD/boxart.jpg
assets.video: $CWD/video.mp4
rating: 99%
release: 1991-01-01
developer: Someone
publisher: Someone Else Ltd.
genre: pewpew

Then you'd run a script that goes through these small metadata files, replaces a piece of text with with the path to the game directory and merges the results together into a /system/metadata.txt file. Something like this:

#! /bin/bash

rm metadata.txt
for i in $(find $(pwd) -name metadata.txt); do
	sed "s|\$CWD|$(dirname $i)|g" $i >> metadata.txt
	echo >> metadata.txt
done

In this example I've used $CWD as something that will be replaced with the file's path. You can use whatever you want, or, if you're good with regex, you could actually use just a dot too and tweak the command accordingly.

(The file format itself is documented here.)

@fluffypillow I'm a noob when it comes to write scripts but yes, I believe you understood what I meant.
My question still is, what will show up in Pegasus afterwards. A bunch of folders with the corresponding games or just the games?
If it's the later that would be perfect.

fluffypillow

@ectoone Just the games :) You can use the script above as-is (save it as eg. get-meta.sh under /system/) or you can use the following one-liner after cding into /system/:

rm metadata.txt; for i in $(find $(pwd) -name metadata.txt); do sed "s|\$CWD|$(dirname $i)|g" $i >> metadata.txt; echo >> metadata.txt; done

I've just made a script that converts the current media layout to the new one, you can get it here. Copy it next to the media dir, make it executable (chmod +x convert_media.py) and run from there (./convert_media.py). It will ask for confirmation before changing anything, but you might want to backup/zip your current media dir first.

Thanks @fluffypillow. I do confirm that I had a wireless keyboard/mouse combo connected to my Pi hence the cursor! Your workaround works nicely. Regarding the player to be honest I don't know. Seems like OMXplayer is the other player available for the Pi but not sure it's as flexible as Gstreamer. I'm wondering if the fact most of my previews are running at 60fps can be a cause of the crash.

SephirothX2004

I have Pegasus running great on my android phone however i would like to request the ability to have different wallpapers for each system if at all possible.

fluffypillow

@nemo93 sorry for the late reply; 60fps shouldn't be a problem, unless GStreamer itself has a related bug (haven't found bug reports about that yet, but could happen). Another thing I suspect is perhaps the Pi is getting a bit hot, causing the playback to crash. Or maybe the system runs out of memory (and/or VRAM). I think if you launch Pegasus through SSH, you might be able to see GStreamer warnings, that might help.

@SephirothX2004 the default theme shows the screenshot for the selected game (if there's any). There's no built-in way to change that, however, it's possible to change the the default theme to load a custom image instead (but that'll need some minor coding).

fluffypillow

And this week's update has just landed:

Breaking Change: the way assets are searched in the media dirs is changed to the model described here, ie. assets for a particular game are now stored under media/<gamename>/)
A script for converting the current layout can be found here
ES2's downloaded_images will continue to work, even with the "Pegasus-exclusive" asset types

Meanwhile I've also started working on themes, and almost finished porting the ES2 Simple theme:

tronkyfran

@fluffypillow WOW!!!!Awesome work as always!! It will have carousel for system selection? Having some more example themes will be a game changer for theme makers(at least for those with less programming savvy as me).
Thanks!!!!

fluffypillow

@tronkyfran yup, that part works too, here's a video: https://my.mixtape.moe/bdfxqx.webm (made mostly out of memory, so may not be 100% accurate). Also using this as a template, it would be possible to port pretty much every ES2 theme to Pegasus too.

halfmanhalfcake

@fluffypillow Amazing work. Look forward to more themes.

tronkyfran

@fluffypillow I was thinking about that port possibility. It would be as easy as make a little script to convert to Pegasus format or are you planning ES theme "support" out of the box? In any case It would multiply the theme choices forma pegasus

fluffypillow

@tronkyfran technically it would be possible to automate the porting, but I'm not sure I want to deal with all the possible cases an ES theme might have (at least for now, we'll see later). I do plan to make the Simple theme commented instead though, so it could be used as a template for further porting.

fluffypillow

Ok, I think the theme is ready for a public release, I've just uploaded it here, give it a try!

What's missing:

help prompts
scrolling descriptions
filtering/searching
page up/down in the game list

Also I've just noticed that unlike in the previous video, background doesn't scroll in real ES2, but I've left it as is (it's more fun this way). The theme code is not really trivial, so I've added a bunch of comments. Feel free to tweak things!

tronkyfran

@fluffypillow OMG! going to test it RIGHT NOW. That theme template is GOLD for me :D
Just one more question, this is a bit crazy and absolutely not a request, but ....now that retroarch is "avaiable" on nintendo switch, do you think it would be theoretically possible to port pegasus there? I have zero knowledge about the hardware, the only thing I know is that its TEGRA based.
Again, Thanks for your work!!!!

fluffypillow

@tronkyfran Yes, in theory it's possible, but I don't have a Switch :)

Mmmmmm, thats one thing we should fix soon enough

Jste84

Has anyone been able to get this working on Android? I'm struggling :(

@jste84 @fluffypillow @tronkyfran happy to do DM log if either of you are on?
