Lakka-LibreELEC VS Playnite

Lakka I believe formats its SD/Main Drive as a Linux filesystem that cannot be accessed easily from a non-Linux device. More info here: https://github.com/libretro/Lakka-LibreELEC/wiki/Accessing-Lakka-filesystem Note: Samba and FTP allow you to wirelessly move files like BIOS files (which go in the storage/system folder as it appears when connected via Samba or FTP, btw) to your Lakka system, and I recommend these methods.

I have an idea for you:

Endless hours of nostalgic fun, especially if you invite a colleague from the same generation.

If you're looking for retro, I'd recommend Lakka OS. I've used it in the past, the only real issue was trying to get to the BIOS/formatting the drive (but I was using a Laptop with fastboot enabled).

Plenty of uses! Install a modern MacOS with Open Core Legacy Patcher (https://dortania.github.io/OpenCore-Legacy-Patcher/MODELS.html). Install Lakka and turn it into a retro gaming device (https://www.lakka.tv). Etc etc. Your model has a Thunderbolt connection so you can get an Thunderbolt enclosure + SSD and install the OS there. It’ll be a lot faster than the internal HDD. Of course you can swap the internal drive but with iMacs it’s always a hassle.

Check out https://www.lakka.tv/ is an OS designed for retro gaming on low powered devices like thin client PC's and rasberry Pi's etc.

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.
