I'm not sure how to help, but so much of that game is interlinked with itself, where few things are standalone. It took a while for us to get through it.
Surprisingly, people say the gauntlet at the end is the hardest part, but we got through it pretty painless. It was some door that we missed as we ran through the world's that tripped us up and needed to get a spoiler to continue.
Same when we went through myst as well, the masterpiece one, not the new one.
Despite the limitations though, riven had an absurd amount of "views" or screens to give you the feeling that you were there. When I revisited it, I was afraid after the full 3d version, the kids and I wouldn't adapt to the still frames, but they held up surprisingly well!
It was easier I guess because it was a 3d world. But it was in Farleys house. When you go in through the back after you input the security code, that door stays open. When you close it from the inside, it reveals a tunnel that (eventually with seeds) leads to her private area with her things.
As a nod to this, there is a part in Obduction that does the same thing. If you've never played it, it's well worth it. Just keep the "cyan brain" on when you play!
There is a furniture store in the US called Badcock Furniture. Just sayin'
The closest thing I ever used that backed up actual hardware was a Playstation 1 card reader. At the time I was backing up game saves and porting them to the ps2 for emulation or something i forget exactly.
It was wild to do something like that on your computer back then. A Sony memory card in your PC? Bonkers.
Unlike most apps actually. Adobe PDF has it prominent "use our AI crap" and there is no way to remove it.
