libretro-thumbnails VS Lakka-LibreELEC

I've been trying to pretty up my collection by making sure everything is validated and has the appropriate boxart. About the only things i've had problems with are the Sharp X86000 and NEC-PC98. These have named boxarts/etc found in the libretro git but I can't seem to find any corresponding dat file to link any particular romset with the retroarch database. Has anyone else dealt with this?

I tested this in Chrome with the entire Sega Mega Drive collection (2075 images) from libretro-thumbnails and it took about 5 minutes on my ageing laptop.

On my RetroArch on PC based on Linux the thumbnails are in a subfolder named "thumbnails" in main RetroArch folder. Each system has folders as "Named_Boxarts", "Named_Snaps" and "Named_Titles". Manually downloads could be done in example at https://thumbnails.libretro.com/ or one of the repos in https://github.com/libretro-thumbnails?q=mame&type=all&language=&sort= or in one of the the subfolders in https://github.com/libretro-thumbnails/libretro-thumbnails

I know this one, if that is what you mean: https://github.com/libretro-thumbnails On this page if you click "libretro-thumbnails" and then "MAME" in example, then it is a bit older than if you go straight to the "MAME" repository itself. I guess one is the master that collects all other repositories after a while. But that's just my theory. As far as I know is this the official thumbnails repository for Libretro/RetroArch.

Retroarch just matches console and game name to the artwork it stores on its own github page.

If you'd like to submit the ones you've collected, you can send a pull request to https://github.com/libretro-thumbnails/libretro-thumbnails

Also for artwork check https://github.com/libretro-thumbnails/libretro-thumbnails

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.
