Playnite VS playnite-non-steam-shortcuts

I've done something similar before with Playnite (an open-source PC game library manager), which has an HLTB plugin.

Playnite: The one with the most features and libraries available via addons and has a lot of options for customization. In my opinion the best one available for this purpose.

Here's a project for Playnite 11: https://github.com/JosefNemec/Playnite/milestone/9

As for my LGO, the only other app I've installed outside of the standard launcher was Playnite to consolidate all games into one place as Legion Space doesn't detect everything I have installed and I don't want to manage manually adding games to their launcher.

use playnite instead of the individual launchers.

Here is where I come in and recommend everyone check out Playnite: https://playnite.link/

When I care about supporting a developer or publisher and they offer their product on their own storefront DRM-free, I will often go there to buy. Or I buy from GoG which takes a smaller cut. Playnite lets me launch my Steam and non-Steam games in a seamless fashion. Steam still does a great job as a game installer/patch manager, and helps me discover new games. But I'm not locked into paying them a 30% fee, which is pretty brutal for some smaller publishers.

For anyone with any of the myriad of HDR monitors that prefers to leave desktop mode in SDR RGB, I just discovered that the excellent Playnite game launcher has a feature where you can enable HDR on a per-game basis. Simply tick the "Enable HDR support" option under "Advanced" tab for the settings of the games that you want HDR turned on for. I was previously using the now-abandoned AutoActions for this, so glad to see there's an alternative in a tool I already use.

Not exactly what you are looking for, but I've been using Playnite to launch everything on my computer for years.

2) Import both non-steam shortcuts and Steam games to Playnite (I seem to remember there being a plugin doing something similar: https://github.com/bburky/playnite-non-steam-shortcuts );

Yesterday I was struggling on how to make emulated games (which are directly started from Playnite from the get-go) to have Steam's overlay enabled, and also to be actually shown in the friends list. But I've learned you can install and use this extension for that to be possible.

Ok, if you are somewhat technical and you want to help me figuring this out, I have a lead. Apparently you need to create a 64bit integer out of a crc32 checksum (derived from the name of the executable) and a fixed sequence afterwards. I found this out by looking at the source code of this playnite extension. Look for the "steam_URL" function, it's explained there. I tried to create it but it didn't work, however the extension seems to use a custom Crc class to create the checksums, and I just made it with the builtin python one (from the binascii module). So that's where we gotta look. Take a look at the "shortcuts.vdf" file found in ~/.steam/steam/userdata//config, there you can see all you custom added games and that's the file the extension looks to gather its data. From this, it's a matter of time to figure out how it works exactly, sadly the code ain't very unit-testing friendly so I can't quite extract pieces without some modifications to make it work, but hey, we're getting there. Once we figure out how to produce the integer, it's as easy as running steam steam://rungameid/<64bit integer>.
