Why does vimms lair refuse to put up some consoles

i am a huge fan this website and have been using it since like 2016 its just very strange to me that for some reason there is no library for some consoles which fit in with the theme and also arent bigger files then anything else on this website. why isnt there sega cd, turbo grafx 32x hell even neo geo roms on here the decision is clearly deliberate i just dont get it.
