libretro-thumbnails VS libretro-database

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

If you want to dig in deeper, you can enable rumble for a few games, as well. It's not so simple, though, and will require some work (lots of trial and error). A few PSX games that support DualShock will just treat the analog stick as another D-pad or simply not use analog. These work fine with no tweaking (such as with Tekken 3). Some games will use analog for everything with DualShock enabled. For these you can remap the D-pad to the analog X/Y directions (such as with Wipeout 3). Some games will use separate controls like D-pad for menus and analog for movement, which means you cannot remap (as you'll then lose access to one of the controls). Of those games, there are a few that let you go to their Settings to control how D-pad/analog work, allowing a work-around (such as with Gran Turismo). Some don't, and you simply have to go without rumble. You can find a partial list of games that support rumble here.

FWIW, you can manually download the .cht files here.

yep I did cheats some of the GBA games, but some of the games crashed when I was using it, it's still fine at least it's working, I downloaded the .cht files from libertogithub https://github.com/libretro/libretro-database

Only if you have (1) updated Retroarch and used it’s internal Online Updater to Update Databases, and (2) all GBA your roms came from “known … good copies” from a source specified on their database. For GBA that’s No-Intro validated dumps only.
