So after a few hours of importing games , suddenly games covers stopped getting downloaded accross several platforms ( PSPS/ switch ) The old ones still show but all new games wont download . I tried re-installing both Launchbox and replacing different roms .. Same issue

I am mainly interested in Neo Geo emulation for the sake of healing my by broken childhood dreams of playing arcade games at home . I have been messing around with different front ends, devices and emulators to get this working , I just purchased premium as I hoped I could get something fancy looking on Lunchbox. I am particularly interested in getting the artwork working , though from what I see , this is the most challenging since much of the artwork is missing After some research , it appears Final Burn Alpha and Final Burn Neo cores emulation is more user friendly than MAME emulation . I found this to be the case with other retro handheld consoles , and so I have been using roms that have been specified for Final Burn emulation within retroarch. However I may be wrong , and am open to debate how to best get a Neo Geo and Arcade gaming experience from launchbox II am having issues particularly with media and box art , that I wanted to get my head around, I think the issue is related to the following points . ROM naming conventions For NeoGeo, MAME and Final Burn Roms I noticed all use a kind of shorthand . When Skraping within LB half are found , though half are not for example King of Fighters "kof94.zip' is not found in LB . Though I dont think the ROM is named incorrectly since, other skrapers do work ( Batocera , using Skraper finds most artwork ) . Though the 'kof94.zip' naming convention appears correct right? Boxart for the kof94.zip is found when searching in Skraper.net , so not sure what gives . I have changed the 'skrape as' setting to 'arcade' though this made no difference. Trailing letters after rom name I understand some roms have a trailing letter after , for example 'kof97a.zip' this indicates the ROM is for Asian market . However I noticed others such as kof97pls.zip' and other trailing letters such as b/c/d/e/f . I guess there are revisions of the game , that are denoted with this trailing letter and/ or number ? If there are revisions for each rom or there are have many trailing letters for the same rom , which one do you pick , any particular trailing letter to look for and why? Rom Pack Nonclemture If I were to instead use MAME Rom packs , which version is recommended ? I understand there are many and I think 0.243 are the latest . If using 0.243 Rom pack , there are many different flavours which I have not yet grasped the meaning of : Merged vs Unmerged No CHD vs CHD SL Rom ( what is SL? ) Platforms and sub platform data When I was testing a ROM pack for MAME , upon importing , there was a really nice platform and sub platform organisation that came with the import, for example from the pack , Launchbox somehow knew which were capcom Cabinets , which were Neo Geo and even gave me different Genres ( though games wouldn't launch ) . I have no idea how this worked , I guess its baked in with the latest version . I am guessing this is the advantage of using MAME ? To be honest I would prefer this , if this gives me a good compatibility with Neo Geo Roms and Artwork . Even if it means getting a 300GB rom pack from Archive.org . Though I am just guessing at which version and a bit confused when given so many options for download ( see Nonclemture point)
