I’m an absolute newbie here so i don’t know if it is actually a fix for everyone, course this might be just my pc or me being dumb, but oh well. So i tryed to install some N64 games but an error kept coming up. on lutris gui error accured when i tryed to install “nintendo 64” looked some like this: https://imgur.com/a/yEunc06
and soon i found out you can debug lutris by using lutris -d command ( what a nice discovery ) and did a same thing as i did without debug. i get this:

None
so basically the same thing. so long story short the fix is to get rid of mupen64plus_next and replace it by mupen64plus which accually works in installer script. so insted of having this:
{"count":1,"next":null,"previous":null,"results":[{"id":null,"game_slug":"the-legend-of-zelda-ocarina-of-time","name":"The Legend of Zelda: Ocarina of Time","year":1998,"user":null,"runner":"libretro","slug":"the-legend-of-zelda-ocarina-of-n64","version":"Nintendo 64","description":"","notes":"","created_at":null,"updated_at":null,"draft":false,"published":true,"published_by":null,"rating":null,"steamid":null,"gogid":null,"gogslug":"","humbleid":"","humblestoreid":"","humblestoreid_real":"","script":{"game":{"core":"mupen64plus_next","main_file":"rom"},"installer":[{"merge":{"src":"rom","dst":"$GAMEDIR"}}],"version":"n64","files":[{"rom":"N/A:Select the game's ROM file"}]},"content":"{\"game\": {\"core\": \"mupen64plus_next\", \"main_file\": \"rom\"}, \"installer\": [{\"merge\": {\"src\": \"rom\", \"dst\": \"$GAMEDIR\"}}], \"version\": \"n64\", \"runner\": \"libretro\", \"files\": [{\"rom\": \"N/A:Select the game's ROM file\"}]}"}]}
why not have that:
{"count":1,"next":null,"previous":null,"results":[{"id":null,"game_slug":"the-legend-of-zelda-ocarina-of-time","name":"The Legend of Zelda: Ocarina of Time","year":1998,"user":null,"runner":"libretro","slug":"the-legend-of-zelda-ocarina-of-n64","version":"Nintendo 64","description":"","notes":"","created_at":null,"updated_at":null,"draft":false,"published":true,"published_by":null,"rating":null,"steamid":null,"gogid":null,"gogslug":"","humbleid":"","humblestoreid":"","humblestoreid_real":"","script":{"game":{"core":"mupen64plus","main_file":"rom"},"installer":[{"merge":{"src":"rom","dst":"$GAMEDIR"}}],"version":"n64","files":[{"rom":"N/A:Select the game's ROM file"}]},"content":"{\"game\": {\"core\": \"mupen64plus\", \"main_file\": \"rom\"}, \"installer\": [{\"merge\": {\"src\": \"rom\", \"dst\": \"$GAMEDIR\"}}], \"version\": \"n64\", \"runner\": \"libretro\", \"files\": [{\"rom\": \"N/A:Select the game's ROM file\"}]}"}]}
and then run lutris -i “insteller-script”. i dunno i hope it helped someone
btw im aware that you dont need install scripts to install a simple game on lutris, but i like it 100 times more when everything is automated.
P.S. if devs are somehow reading this. much luv <3
