Announcing Pegasus Frontend

@andershp I never had an issue. I did have an issue now that I can't run pegasus at all if it's transferred from pc to pi. It warns me about some security hole ueid or something..

Installing pegasus from retropie-setup works. I just had to point autostart to the pegasus location.

@AndersHP seems to work fine for me, on a Pi 3 running an older RetroPie install. I'll check if it happens with the latest version. Do you see anything weird in the logs of Pegasus or runcommand?

@Darksavior interesting, can you check the exact warning message? There was also a Permission denied error report some time ago, and it turned out users cannot launch executables on NTFS file systems by default.

@AndersHP also works fine on an updated RetroPie, hmm.

Also the weekly changelog (or rather, a summary):

large number of internal changes, as a base for future updates (post)
new config file proposal (post)

In addition, I've just added theme reloading support (with F5); will likely come handy in the future. And since we've also reached alpha4+100, I've reset the counter, we're now in the alpha 5 phase (yay!).

@fluffypillow I still get a permission denied trying to run it if transferring manually. Pegasus transfers with 644 permissions from windows to my pi. I need to change it to 777, and then it works.

I checked now and I don't get the "security hole" error anymore. The only different things I've done was updating retropie and deleting any old pegasus config entries when I decided to make things easier to just install it from retropie-setup and add THAT location to autostart. So now I'm running pegasus from /opt/retropie/supplementary/pegasus-fe/

Any chance that config might also allow users to adjust the tile rows?

fluffypillow

@Darksavior The number of rows visible depends on the images and your screen size. Since that's the direction you scroll, I don't plan to limit their count.

I you mean columns thought, yes, I'd like theme-specific settings in the future, where things like this could be tweaked.

In extension of an update to Retroarch 1.6.9 going bad, I have to either go back to my backup of 1.6.7 or try a fresh install.. But I just realized that the downloaded_images folder is on the sd-card... Sorry if this is slightly offtopic, but still a bit related to Pegasus:

will moving the entire scrapings to the USB with the ROMS (yes, running roms off USB) slow pegasus down instead of having these on the sd? In the future, it could be cool to have scrapings and roms together, in case I need to start all over (again).
If no to above's speed question: Is there a way to move these maaaaany many files a fast way? I can only access the sd when it's placed in the pi, through Filezilla, putting it in my mac only shows very few folders and files.

fluffypillow

@AndersHP Unfortunately, yes, loading is currently slower if your assets are on USB (Pegasus checks which files are accessible, and that's slow). However, this could be improved, and it's exactly something I plan to fix in one of the next updates.
As for Mac, apparently there's something called OSXFuse you can use to mount ext4 file systems. No idea if it works though.

AndersHP

@fluffypillow Thanks for the reply. I will stay with Retroarch 1.6.7 until your next updates then.

AndersHP

Anyone else in here experiencing problems with Retroarch 1.6.9 stated here?

It would be nice to know if this is related to Pegasus.

No. Everything is fine here. I must've updated Pegasus last week from retropie setup if it matters.

fluffypillow

@AndersHP Pegasus doesn't touch your emulators, and can only run when you launch it. If the problem occurs using other frontends or when Pegasus isn't even installed, I assume the problem is caused by something else.
You've mentioned it works fine with RetroArch 1.6.7 but slows down with 1.6.9, looking at the changelogs (1, 2), I see lots of changes; perhaps some of them are causing you trouble? Or maybe during the update to 1.6.9, something got wrong (eg. during the build)?

AndersHP

In this thread I can confirm that my issues are gone after a simple .cfg file deletion and regenerating.

fluffypillow

Yet another huge patch has just landed in Pegasus: this time I've updated the way games, metadata and assets are found, resulting in improved loading speed.
On my Pi 3 with a Class 10 SD card, I have 3400 games and about 10800 assets; it is loaded by Alpha 5 in about 8-8.5 seconds, while the latest Pegasus loads them in 3.4-3.6 seconds, making it over twice as fast.

Of course, your mileage may vary, as I've only tested it on a Pi 3 + SD card; I'm not sure how much it brings on eg. USB drives.

Great work :)

Any ETA on a theme guide? I've tried to play around with QT Creator but no luck in terms of a working theme

AndersHP

@fluffypillow impressive work, can't wait to try it out. What about placing images on USB, will this be equally fast or still faster on SD?

fluffypillow

@halfmanhalfcake hopefully before Christmas :) The plan is that now I start working on the config file format, as it'll be used by the themes, then I start writing the theming guide.

@AndersHP as far as I know, they both should have the same possible reachable speed on a Pi. But unless you have a very fast SD card (UHS class), USBs in general might be faster.

AndersHP

With about 5000 games read from USB and assets off SD, Pegasus loads in 21 secs in Alpha 5 but 24 secs in the newest release. Maybe I should try moving artwork to USB also... Should this just lie in the roms/media folders?

fluffypillow

@andershp hmm this difference is really interesting... I'll see if I can figure out what causes this slowdown. As for game assets, they are searched in [game's directory]/media, see this comment.

AndersHP

@fluffypillow My USB drive with the games are probably not very fast, and I have video, logo and boxart per game, ran from the microSD (class 10).

Assembling all these on the USB thumbdrive, maybe a faster one, could bring the loading time down I guess? But still, it's quite a lot more time than your setup? Maybe a fresh Retropie install is needed?
