Announcing Pegasus Frontend

@fluffypillow I don't know what all that means, but I sure am excited to get this installed on my Pie. What about all the artwork scraping ? Your video shows beautiful artwork images and fast scrolling, I guess Pegasus pushes the limit of which size images you can use? But how did you scrape, is it going to be a feature that's built in, or is it manually finding artwork on google for starters..?

Oh, and by the way. Pegasus won't be limited to widescreen monitors, right?
Because if it won't support 4:3 or 5:4, I'm going to cry.

One of Pegasus features is:

ES2 config compatibility: Pegasus can use ES2's gamelist files, no need to invent a new set of tools.

ES = EmulationStation.

Happy birthday for anyone who has it today! And a very merry unbirthday for the rest of us!

@meleu ah yes, on-screen keyboard is also on my todo list :)

@AndersHP At the moment assets are searched for in a subdirectory of the rom directory, see https://retropie.org.uk/forum/topic/9598/announcing-pegasus-frontend/52, while metadata is read from ES2's files. I've used Universal XML Scraper, but anything that works with ES should work fine.

There's no limit on the size of the image files, they'll be downscaled on loading automatically.

Pegasus itself works with all kinds of aspect ratios, you can even resize the window: https://snag.gy/alJfWv.jpg
As for how it will look, that depends on the theme, but in general you could even make it work in portrait mode.

@fluffypillow Amazing.. Is there anything that Pegasus can't do? Will it make me a cup of coffee?

fluffypillow

Well, if you have a USB/GPIO coffee maker it can control... :)

@fluffypillow after many hours of trial and error I managed to get Qt-everywhere to compile, but now I am having problems compiling pegasus-frontend itself, I get this error:

do you have any idea what might be the problem?

Thank you!

It seems you're trying to do a static build, but some plugins are either not available, or not linked to the final binary. You should see eg. -L<QT PATH>/plugins/imageformats -lsvg in the linking command.

Static build may require some additional tweaking, because the compiler also has to scan the QML files to figure out which additional plugins will it have to link to the binary. I haven't set up an automatic build test for that yet, but I plan to (there are a lot of build parameters that can be tweaked!), but I plan to.

Also if you're on desktop linux, you won't have to build your own Qt, you can use the official release (unless of course you explicitly want to do a static build or want a Qt with some additional tweaks).

Thanks! I recompiled QT without the static flag and now it seems it compiled, but I do have a small problem.

mkdir: cannot create directory '/opt/pegasus-frontend': Permission denied

Since this is not retropie the /opt folder does not exists, is there an option to change this while compiling it?

I can see the Makefile has several lines hardcoded:

mkdir -p $(INSTALL_ROOT)/opt/pegasus-frontend

not sure if that can be changed.

Edit: nevermind, I should have read the building Wiki!

Thanks!
