I’m using Lakka nightly devel-20161221183631-r21729-g274b40f (installed via) lakka-update System is an X86_64
I installed boxart from “Online Updater > Thumbnails Updater” from the RetroArch main navigation. I configured RetroArch to display “Snaps” (vs boxart or titles).
My playlists properly display most snaps. However, some snaps with seemingly valid names do not appear.
Using Atari 2600 as an example (with valid No-Intro roms that properly scan for playlist generation)…
From my Atari - 2600.lpl /storage/roms/NO_INTO/Atari/ATARI_2600/3-D Tic-Tac-Toe (USA).zip#3-D Tic-Tac-Toe (USA).a26 3-D Tic-Tac-Toe (USA) /tmp/cores/stella_libretro.so Atari 2600 (Stella) 58805709|crc Atari - 2600.lpl
The rom scanner properly identifies the rom as 3-D Tic-Tac-Toe (USA)
ls -l /storage/thumbnails/Atari - 2600/Named_Snaps/3-D*
-rw-r--r-- 1 root root 302 Feb 14 23:00 /storage/thumbnails/Atari - 2600/Named_Snaps/3-D Tic-Tac-Toe (USA).png
An image does exist that matches the rom name (as it is known to the rom scanner and as it appears in the playlist). However, it is only 302 bytes in size.
From a somewhat cursory examination of other images similarly “missing” when viewing the Atari 2600 playlist, it seems that that only images with file sizes larger than ~900 bytes are displayed. Of course, I may simply be seeing correlation when there is some other actual cause of the omissions.
I’ve noticed similar “missing” images in FBA Arcade roms as well (when there is indeed a properly-name image file in the appropriate ~/thumbnails/ subdirectory. This phenemenom is not limited to the Atari 2600 playlist.
Anyone have any ideas?
