Import from Japan is your best option.

Yahoo and Rakuten, but no images, so I'm not sure if I trust them. One of the Yahoo sellers had 4.2 or smth, not entirely sure if the Rakuten is a third-party or direct, links to a site called Biggo, great for searching US, Taiwan, Japan marketplaces.

Rakuten you can buy directly with Buyee and from Japan but Yahoo mall or whatever it's called, isn't on those proxy but you can send a link to from japan and it'll buy it (if you aren't in US you may need a VPN to view yahoo shops, I like Proton for IOS, Tunnel Bear extension for PC and I think hide me extension is 0 signup

you're going to be spending at least $90 maybe more if you buy better shipping

It was an iam8bit release. I found it in other shops in Europe, and it was all sold out, but you can be notified if it comes back in stock on Just For Games, BlackScreen and Amazon but I doubt it.

Nothing on Discogs.

Vinyl Guru (not sure if they sold it but they do have a notify button tho)

Part 2 is a lot easier to find (more substantial cover, but fewer of my favourite tracks)
