Announcing Pegasus Frontend

fluffypillow

the terminal (including whatever's left of code there) is still shown for a second

Hmm, not sure how much control I have over that -- it's already the launched program's "territory". As a workaround, you could try running clear when the system boots (eg. by adding it before Pegasus in /opt/retropie/configs/all/autostart.sh), or editing runcommand itself (/opt/retropie/supplementary/runcommand/runcommand.sh, I think) to call clear first.

segmentation fault

Good to hear it works, and thanks :)

I still cannot get into runcommand menus

and @Darksavior: couldn't fix that yet, sorry :/ I haven't found out the exact cause of this bug yet, but I'll keep trying, and dig deeper in the low-level platform code.

@honorio96 sure, this could be improved. I've mainly tested on 720p, but I can add bigger/smaller logo images for other resolutions.

thanks @fluffypillow for your clear explanations. I did learn something! Indeed after the replacement of every "&" characters it's all fine. Therefore I'm now using your frontend as default. Do you mind if I share some further issues/feedback in this space?

Mixed cases/boxarts. Sounds like cropping is the straightforward answer here. Perhaps for some cases you can rotate them left or right and on hovering rotate them back to their original view. Not sure I'm clear but anyhow it shouldn't be a good fit for all cases. For SNES the Japanese covers will need cropping as rotation here won't help.
Sound. Depending on video snaps/previews sometimes sound can be low/loud. Any chance to have an option to control sound volume? Even better would be a volume limiter to not go above a specific level.
Marquees. Despite having them in my ES2 gamelist.xml files they don't show up. I'm using tag <marquee> and all files are present. Not sure what's going wrong.
Players count. Like #3. I have the <players> tag in my ES2 xml but nothing show up in Pegasus.
Genre. Same as #3 and #4. The <genre> tag is there but none appears in Pegasus.
Rating. Same as #3, #4 and #5.
Video previews. Possible to play these only once? To have an option to play them in a loop or not would be nice.
Fullscreen. I'm not sure but it seems that Pegasus UI is a bit zoomed-in. The selector on top with the different systems looks a bit cropped. It might be just an impression but definitely the systems selector on top doesn't look the same as in your preview from your 1st post. I didn't have any screen issue with ES2.
Logos. In the logs (lastrun) I can see that "mame-libretro" and "pcecd" are not recognized hence their logos don't show up in the systems selector. For "mame-libretro" I'm not sure as I'm using standard from Retropie I guess if I rename everything with "mame" it should work but that sounds a bit tedious :) For "pcecd" this is a system I've added myself and I'd be happy to have a logo for it as well. It's the PC Engine CDROM.
Favorites. I'm not sure where the favorites are located. I can see a favorites.txt in the Pegasus config dir but that's all. To have something similar to ES2 where you have a "new" system created with your favorites games listed would be nice.
On-sceen help. I was a bit lost without indication the first time I tried the frontend. To have some indications in a form of a bottom bar like ES2 where various buttons+description would be nice. I was always hitting the "start" button of my X360 controller to access the options screen (I'm used to ES2 definitely!) but with Pegasus this button launches the games! Such help would ease the transition from ES2 to Pegasus.
Jump-to-letter and filters. Not sure how to use these. The "Y"/yellow button on my X360 does nothing.
Updates. I'm using Retropie and I can only update Pegasus "from binary". Not sure how to get the latest release with your latest commits. For instance how to get the playtime tracking you just added on week 67?
Hidden tag. I'd like some items from gamelist.xml to not show up in the UI (eg. bioses). I'm using the <hidden> tag today but perhaps there's another way to do that.
Games order. File name sorting is working. Awesome \o/ However I do see weird ordering on some occasions. For instance, Gun Force 2 (Geo Storm) is sorted before Gun Force: Battle Fire Engulfed Terror Island. Or Macross II (Super Dimension Fortress) before Macross (Super Spacefortress). Another example would be with the Street "Alphas" where Street Fighter Alpha: Warriors' Dreams (Street Fighter Zero) is sorted last after Street Fighter Alpha 2 (Street Fighter Zero 2) and Street Fighter Alpha 3 (Street Fighter Zero 3). Last example with SF3 same as SFA you've got Street Fighter III: New Generation after 2nd and 3rd Strike. These are the actual names I'm using in my gamelist along with the tag <name>. I don't mention it because I know this is rather complicated but the Mortal Kombats are not sorted properly as well. I suspect this is due to the II(double i) instead of a number in the title. Perhaps something could be done by mixing name with release date together? That way you're sure Mortal Kombat II can't be listed after Mortal Kombat 3. Not sure it works for all situations though.
Pegasus config files. I've spent some time to study your collection/metadata files structure. It's brilliant. I'm converting my ES2 files right now. My feedback is that I don't like to have a .txt file in the roms directories. I'd like to keep things tidy. Would it possible to store those files in pegasus-feconfig directory instead? So that everything is kept at the same place :)
List wrap. Would it be possible to get back to the top of a game list after pressing the down button from the controller? I mean whenever you get to the bottom of a list (and some lists can be huge like NES with 1000+ games) if you want to go back to the very top of it the only to do that is pressing the trigger several times. It can be tedious with larger lists.
In ES2 after launching a game if I press quickly on a button ("X" on X360) I can reach out a "debug" screen where I can change some parameters like emulator type/name, showing games covers, resolutions, etc. Is it a feature of ES2 or something else? I'd be happy to have something similar in Pegasus.
My use case is as follows. There are several MAME versions out there and some games work better with a specific version than other. Whenever a game requires a specific version other than the default "lr-mame2003" I launch this game then hit the "X" button. Finally I do select a specific MAME emulator I'd like to use for that game. I can then see the game and emulator are then added to the emulators.cfg file under Retropie > configs > all directory.

Thank you again for making this really great frontend.

@nemo93 thanks for the feedback! Let's see...

All videos are played on the system's volume level by default. While it'd be certainly possible to write an audio normalizer, unfortunately I'm not an expert in this topic to implement such a feature. I think FFMPEG or similar video editing tools could help with this, however.

3-4-5-6. These properties are detected from the ES files, but currently aren't used in the default theme. They might be in future!

Perhaps clicking on them could pause/start the video? (if you have a mouse/touchscreen, of course)
Yeah that bar might be a bit too slim (especially on small screens), I'll see if making it bigger would look better. As for the fullscreen, if you see the whole logo for the system, then it's OK, Pegasus itself shouldn't crop the screen.
Yes, the main theme only has image for mame. I'm not familiar with MAME, does this libretro version have a separate logo in RetroPie/ES? As for PC Engine, there's a logo for pcengine, would that be good or the CD version has a different logo? You can find the currently recognized names here, if you have some nice vector images, I can add them.
Yes, they are stored in favorites.txt, and you can use the filter panel (Shift/PS-Triangle/Xbox-Y) to show only your favorites -- except opening this panel apparently broken using the gamepad, and I forgot to fix it. Other than that, the separate collection approach could also be done, it's just not implemented yet.
Yeah I really want to add some kind of first start setup/tutorial screen, and also a help screen in the menu. I think the main theme would be a bit cramped with yet another bar, but other themes are free to show the controls.
The button's broken using gamepads, will fix it :)
RetroPie always downloads the latest release, as soon as it's available. There might be a separate stable/latest option eventually, but I still want to improve Pegasus a bit before that. I also plan to add an update checker eventually.
I'm not sure how official this hidden tag is, it doesn't seem to be documented. Looks like this property is a metadata, so I should keep the games in memory, but make them invisible? That sounds like a waste... (Ignoring files is also possible using Pegasus' own config format, if you're willing to use it)
Yes, they're sorted by file name, but they indeed should be by title. Will fix it in a minute.

nemo93

I've added #14 and #15 :) Thank you for the responses. It's clear for me now.

Sounds good. Actually if you can find a way to pause/start video for people with only controller (like me!) that would be great. Perhaps a controller button can be assigned or you can hover the video and click on it with "A"/select button.
It should be the same mame logo. It's called mame-libretro to make difference with the various versions included in Retropie (eg. mame-mame4all, mame-advmame, etc). All these should be assigned the mame logo. For PCE CD it does have a different logo. You can get one here or here.

Thank you!

fluffypillow

@nemo93 also added #14 and #15 :) Thanks for the repo link, will check it out.

nemo93

to be honest I start wondering where I did hear about such tag... Anyhow I'm keen to understand a bit better your config format. I'm not sure how to proceed though. Thanks to your excellent ES2 <> Pegasus converter I can create metadata config files. Should I create one config file per system eg. nes.metadata.txt, snes.metadata.txt, megadrive.metadata.txt and so on? And then another files nes.collections.txt, snes.collections.txt etc?
Let's assume Neo Geo for the sake of simplicity. I'd like to "hide" the bios name entry from the games list (the famous neogeo.zip). How should I proceed please? From your doc I'm not sure how both "collections" and "metadata" articulate with each other. Sounds like "collections.txt" is similar to es_systems.cfg but not 100% sure. Any example appreciated.

I understand you might be on some well-deserved holidays. If so please no rush! Everything is running absolutely smooth already :)

Thank you

fluffypillow

@nemo93 A collections file is kind of like es_systems except it's local to its directory, ie. it will only search in the directory it's placed in (and also the subdirectories). It's task is to decide which files (in the directory) belong to which collection(s). The metadata file is pretty much like a gamelist.xml: it just adds information to the already found games, but doesn't add new games.

A per-system file in each directory might be better, unless each system use different extensions. The file names are always just collections.txt and metadata.txt, eg. /home/pi/RetroPie/roms/neogeo/collections.txt. Then you'd add /home/pi/RetroPie/roms/neogeo to the game_dirs.txt.

Now to actually ignore a file, you'd just use ignore-file; your collections file would look something like this:

collection: Neo Geo
shortname: neogeo
extensions: zip
ignore-file: neogeo.zip
launch: /something/myemulator "{file.path}"

I've just fixed the title sorting and the Y button, and also reworded/slightly extended the collection format document.

It is part of the Kids Mode as far as I know. https://github.com/retropie/retropie-setup/wiki/Child-friendly-EmulationStation

@ectoone Ah, that makes sense, thanks.

nemo93

Thank you again @fluffypillow, really awesome. And fast as well :) I'll continue posting my feedback.

Thank you again, this is really impressive and great frontend.

fluffypillow

@nemo93

That's a really interesting topic actually, from science perspective. Programs tend to sort simply based on the letters, so to make it human-like, they'd need some actual understanding (like II is 2, for example). I wonder if there's a good algorithm for that, looking around on game listing sites or in other project, I haven't found a case where all your examples would work fine.
That's on my todo list, for quite some time now :) Shouldn't be hard to add, just haven't had the time yet.
Fixed, will be online in an hour. Holding down the button also works with keyboards, but gamepads seem to be buggy at the moment.
If you mean the runcommand screen, then yeah, that's a bug, for some reason console UIs doesn't seem to work well. Hopefully I can fix it.

Also the thread just hit the 100K views, yay :)

nemo93

I've made a slight attempt in reorganizing a bit the thread with my many questions/comments.

Logos. In addition to the 2 missing logos mentioned above I realized that both "Megadrive" as well as "Master System" are sorted after NES and PC Engine right before Super NES. I guess this is because they're considered as "SEGA Megadrive" and "SEGA Master System". Any chance to have them sorted without this SEGA in front? So that they appear in the top-menu systems right Mame and before NES?
Games order. Indeed :) To me the only way to do that is by following the order provided in the gamelist/metadata file. Or at least to give users a choice to either sort by filename or to sort using the exact order from the metadata file.

And that would be all for me. I stop posting comments for now as the frontend is working great already! Thank you again.

fluffypillow

@nemo93

Systems are sorted by their full names; the abbreviated form (shortname/ES2 <name>) is optional in Pegasus, but if it exists, it will be used for finding the logo image and shown on the bar, instead of the full name. There's no custom collection logo support yet, so as a workaround you can only change the full name for now :/
Sorting support will be added in the future™, though actual usage of it will depend on the theme.

fluffypillow

@nemo93 Unfortunately I had to revert the game list wrapping: due to a bug in one of the dependencies, this makes other keys (especially Esc) unresponsive. I've reported the issue to the developers, will re-add the wrapping as soon as it's fixed.

fluffypillow

I'm a bit occupied with other projects at the moment, there might be no updates this week either :/

shaolinbastard

I’m probably missing something really obvious, but how do you make a game pad player one? Currently, I’m using a USB wireless keyboard to type the command that launches Pegasus, so the keyboard defaults to first player, meaning I can’t use my Bluetooth game pad to start a game once it’s selected. Only player one, the keyboard, can control anything in game. I can, however, use the game pad outside of the game.

Darksavior

@shaolinbastard Pegasus has nothing to do with a pad/kb being player 1. Install joystick-selection to assign your pad as player 1 or disconnect the keyboard. I don't remember which section of retropie-setup that's in.

fluffypillow

Yes, Pegasus itself works from both keyboard and gamepad; what an emulator/game considers P1 then depends on that particular program.

shaolinbastard

@darksavior Thanks! I'll poke around with it more this weekend. I love how much this frontend is progressing and think the UI far surpasses any theme I've tried for ES.
