@voljega. "it seems you're feeling like you're entitled to have evrything you want whenever you want"
That is insulting and really unfair - and also untrue.
I have just spent on average 4 nights a week over the last 3 months going thru huge rom collections for every system covered by Recalbox, removing all the duplicates so that there is only 1 version of each Rom (ideally the USA one) and manually removed every duplicate from the 0.78 mame folder so I only had the circa 2300 unique games.
I have also now in my own time downloaded and resized hundreds of box art so every single file has one, due to wild results that the scrapers seem to throw up when left on automatic.
If I wanted "everything now" id have just downloaded someone else's setup available online.
