Announcing Pegasus Frontend

@fluffypillow I can not wait to see a possible future RetroPie release with Pegasus by default

@fluffypillow Thank again for this wonderful frontend !

fluffypillow

Happy new year update! The winter holidays are over, and so I've also continued the development with some updates.

Main changes:

Added support for WebP and animated PNG image formats: themes now have the ability to use, and optionally, to enable animation on them (Note: APNG images should have .apng file extension to work)
GOG support is now turned on by default again
Minor Android improvements

Theme changes:

You can now use WebP and APNG images: similarly to GIFs, the QML AnimatedImage element (https://doc.qt.io/qt-5/qml-qtquick-animatedimage.html) can be used to display them animated, and the regular Image to display still images

Tool changes:

Updated the RetroArch command on the Android metadata generator page

Notes for maintainers:

WebP support requires Qt's imageformats module with WebP support
APNG support requires libpng with animation support (ie. the "APNG patch"). libpng might come from various sources (system/Qt/other library/custom), but this feature may not be enabled on them - to avoid breaking builds, APNG support in Pegasus is NOT enabled by default. You can define the ENABLE_APNG QMake variable to enable support. For the same reason, Pegasus also does NOT try to link to libpng automatically. Similarly to SDL2, you can use the PNG_LIBS and PNG_INCLUDES QMake variables to affect the build.

Is it possible to start Pegasus on a category such as Arcade?

It seems kind of "exhausting" to add all of the game lists manually to Pegasus.

So I propose a few ideas:

A simple GUI program that let's you make metadata files much more easily on OSes. Instead of doing it the old fashioned way:

# Selects all files with the provided extension, except two games
collection: Super Nintendo Entertainment System
shortname: snes
extensions: 7z, bin, smc, sfc, fig, swc, mgd, zip, bin
ignore-file: buggygame.bin
ignore-file: duplicategame.bin
launch: snes9x "{file.path}"

# A collection of 3 games. They're also part of 'My Games'.
collection: Platformer games
files: mario1.bin
files: mario2.bin
files: mario3.bin

# A regex example; includes games with '[number]-in-1' in their name.
collection: Multi-game carts
regex: \d+.in.1

An auto-detect program that you drop in where you want it to find the games based on very simple "[systemname].txt" files stored in the ROM folders themselves (and [emulatorname].txt for the emulators)
Better integration with RetroArch that converts everything you already set up in libretro, and uses Pegasus to open it.

But those are just my suggestions, let the debate commence.

@h2805270 There's actually a GUI tool for metafiles (even if it's a bit simple): https://github.com/mmatyas/pegasus-metadata-editor

Hi!
It would be possible to install pegasus on a chromecast with google tv? in theory its just an android underneath, but Im not really sure. Well, anyway I bought one and will try this weekend, so ill tell you if I succeed, just wanted to know if anybody tried it beforehand. Thx for your work @fluffypillow !!!!

tronkyfran

@tronkyfran Yep, it works!!!!!

@grila said in Announcing Pegasus Frontend:

Hi @fluffypillow . I recently received my Retroid Pocket 2 and am in the process of setting up with Pegasus. The RP2 comes with 2 versions of RetroArch, a up to date version and an older 1.5.0 version that is specifically for playing GBA.

My problem is that I can launch the up to date version thru Pegasus, but when I try to launch a GBA game with the 1.5.0 version of RetroArch it just exits immediately and returns me to Pegasus. (The 1.5.0 version works correctly if I load roms directly in RetroArch)

Here's my GBA metadata file and my lastrun.log

My guess is it has something to do with the launch parameters, but I've rooted the RP2 and double checked all the directories and they are correct.

If you have any suggestions it would be appreciated. Thanks!

I've found the solution for this for anyone in the future that needs it:

collection: Nintendo GameBoy Advance
shortname: gba
extensions: gba, zip

#For the Retroid Pocket 2 special version of RetroArch for GBA

launch: am start --user 0
  -n com.gpsp/com.retroarch.browser.retroactivity.RetroActivityFuture
  -e ROM {file.path}
  -e LIBRETRO /data/user/0/com.gpsp/cores/gpsp_libretro_android.so
  -e CONFIGFILE /storage/emulated/0/Android/data/com.gpsp/files/retroarch.cfg
  --activity-clear-top

I've got a beginners question.
Im surfing the pegasus wave on my new Chromecast right now, but I lost track on how to scrape and generate metadata files for a bunch of roms(roughly 3 systems and 100 roms per system). I know how to do it the "hard" way(via documentation) but dont want to get into it and realize one week later that there is an easier way. Im looking for something too easy?

Thanks in advance!!!

@tronkyfran Skyscraper has built-in Pegasus support, and the Generic Emulator output of Skraper can also be loaded (though that doesn't have the emulator launch informations).

fluffypillow

Also a minor weekly update!

Fixed storage access issues on Android 10
Fixed games not present in metadata file collections
Added Arabic translation (thanks phwright!)
Updated the list of automatically recognized gamepads
Linux: Fixed out of date APT repository packages
Themes: Updated the Famicom Beach theme with authentic animated fire (thanks SecularSteve!)

I'm a bit at a loss here and require some help regarding ScummVM and game images and metadata.
I have setup Pegasus with Retroarch and a few standalone emulators on my old Win10 Laptop.
laptop specs are i5-2410M, 8GB RAM, Intel HD3000 on board graphics

I was able to setup NES, SNES, MegaDrive and so on with ease using Retroarch and Skraper.
Now I am trying for hours to get the images to show for my ScummVM games. Screenscraper is currently down so I thought I'll add the data for those 3-4 games myself inside the metadata.pegasus.txt file.
But for some reason that I can't seem to find or see it won't load any images nor any game info like description.
Usually Pegasus recognizes the folder structure by itself and loads the correct images and metadata. But right now I get this

alt text

The games run just fine using ScummVM as standalone, not as core from Retroarch. ScummVM starts and loads the game which I choose using the following launch command inside the metadata file

collection: ScummVM
extension: residualvm(residualvm), scummvm(scummvm), svm, zip
launch: C:\Users\***\Desktop\Pegasus\Emulators\scummvm\scummvm.exe -c C:\Users\***\AppData\Roaming\ScummVM\scummvm.ini {file.basename}

Even if I remove anything else but the launch command code games will run. which is strange because I'm using the variable {file.basename} which would mean it takes the name without extension from file: monkey2.svm, right? Even if i remove monkey2.svm the game will launch and run just fine. So not sure where {file.basename} takes the name from. But removing {file.basename} will only launch ScummVM menu without any game loaded.

Anything else I add into that metadata file has no visual effect on the pegasus frontend. Even if I use the assets paths directly it won't show anything.

My file structure is like this (example with monkey island 2)

Pegases/Roms/scummvm/Monkey Island 2/monkey2.svm
Pegases/Roms/scummvm/Monkey Island 2/MONKEY2.000
Pegases/Roms/scummvm/Monkey Island 2/MONKEY2.001
Pegases/Roms/scummvm/Monkey Island 2/MT32_CONTROL.ROM
Pegases/Roms/scummvm/Monkey Island 2/MT32_PCM.ROM
Pegasus/Roms/scummvm/metadata.pegasus.txt
Pegasus/Roms/scummvm/media/box2dfront/monkey2.png
Pegasus/Roms/scummvm/media/screenshots/monkey2.jpg
Pegasus/Roms/scummvm/media/videos/monkey2.mp4
Pegasus/Roms/scummvm/media/wheels/monkey2.png

Any metadata info I add to the metadata.pegasus file doesn't seem to have any effect except for the launch code.
Adding metadata like this won't show at all in the front-end

game: Monkey Island 2: LeChuck's Revenge
file: monkey2.svm
developer: LucasArts
publisher: LucasArts
genre: Adventure
description:
  Guybrush Threepwood, the mighty pirate who can hold his breath for ten minutes, could have lived quietly and happily with his sweetheart Elaine, the governor of Melee Island. But the restless pirate spirit won't let Guybrush in peace. Things don't go very well with Elaine, and Guybrush (now with a beard) embarks on a new adventure: searching for the legendary treasure of Big Whoop. However, the evil ghost pirate LeChuck hasn't left the stage yet. His subordinates are trying to bring him back from the dead one more time. Will Guybrush be able to defeat his archenemy again?
release: 1992-01-01
players: 1

Is there something I missed regarding paths or setup for ScummVM? Any help is appreciated. Thanks

Sometimes a short break can do wonders.
With a fresh mindset I tackled this once more and I found the mistake. And what a small mistake it was, I could kick myself so hard now. To setup ScummVM for Pegasus I took the retropie ScummVM docs as reference and there it says the following...

/home/pi/RetroPie/roms/scummvm/Day of the Tentacle/Day of the Tentacle.svm
/home/pi/RetroPie/roms/scummvm/Day of the Tentacle/MONSTER.SOU
/home/pi/RetroPie/roms/scummvm/Day of the Tentacle/TENTACLE.000
/home/pi/RetroPie/roms/scummvm/Day of the Tentacle/TENTACLE.001

Having the svm file within the same folder as the game files was the problem for me. I had to move the svm file outside the game folder. Taking that example from above the correct solution for my case is this folder structure

/home/pi/RetroPie/roms/scummvm/Day of the Tentacle.svm
/home/pi/RetroPie/roms/scummvm/Day of the Tentacle/MONSTER.SOU
/home/pi/RetroPie/roms/scummvm/Day of the Tentacle/TENTACLE.000
/home/pi/RetroPie/roms/scummvm/Day of the Tentacle/TENTACLE.001

Now finally all images, screenshots and metadata is showing up correctly and the games still launch fine as they should. Meaning it recognizes the metadata.pegasus file. Thanks and sorry for the fuss.

- They can be added to games like the rest of the assets, with the name titlescreen
- They are also imported automatically from Skraper and LaunchBox sources
Improved handling of symlinks and Windows shortcuts (.lnk files)

@fluffypillow Do you happen to know the ideal way to get pegasus working on a mac mini m1 (arm64)? Maybe the emulationstation content might be readable if I can alter the folder pegasus is looking for, but then there's the actual games to load from retroarch which requires retropie to do it.

fluffypillow

@darksavior I'm afraid I'm not familiar with the Mac, sorry :( If it helps, ES system files are expected to be at $HOME/.emulationstation or /etc/emulationstation/, though if I remember correctly, Mac support for ES was implemented in just one of the forks.

Darksavior

@fluffypillow No worries, just thought you might know a way. I'll use the standalone retroarch for now.

@fluffypillow

I'm new to Pegasus and have been looking at videos of it on YouTube. It looks fantastic and great work so far :)

At the moment, it seems too difficult for me to set up. I know other front ends allow you to just simply select your roms folder (without having to create a metadata.pegasus.txt) and then there's options to use an in-app scraper to download artwork.

Will these options eventually be available in Pegasus? And if so, is there a road map of features you want to incorporate?

Thanks!
