Another thought, is most of this stuff is pretty softcore compared to what's available online today. You're essentially looking at 240p GIF images of babes, with pixellation due to the limited pallet. I imagine much of it would be bikini shots, possibly bare chest shots if you're really lucky. Compared to actual games like Strip Fighter, where there is reward for playing, you're just looking at non-explicit softcore nudity or possibly even tamer PG-13 shots of woment in bikinis, at much lower resolution than say you would find in a Sports Illustrated Swimsuit Issue. With instant HD gratification for free on the internet, I imagine it would be hard to get off to any of it, and just watching a slide show would IMO be boring. I bet anyone buying this today as a collector would probably put it in their Duo, watch it one time, be like "Mmmm-kayy..." and take the disc out to place on a shelf, never to be inserted again.
I own a number of "adult" oriented video games, Beat Em and Custer's for Atari, and a repro with all three Panesian titles on NES, as well as Famicom Soap Panic and AV Pachinko from Hacker International. I've also got a sealed Strip Fighter II on the way; can't wait to pop the shrink wrap on it. To me the allure of "adult" titles for retro systems is the sheer cheesiness of the gameplay as well as the pixellated graphics in the money shots. It can be quite comical, especially to imagine that some poor kid, or kid's parent somewhere in some place in time actually tried to fap holding a joystick in one hand and a manstick in the other.
Sitting through a borderline PG-13 to softcore slide show would do nothing for me. In fact it would not surprise me to learn that a recent mainstream flick like DeadPool had more tit shots in it than these vintage slideshows. No comic relief of crudely drawn strippers during gameplay intermission because there is no gameplay. In fact crudely drawn 8-bit pr0n is far more hilareous than 16-bit digitized photos of real centerfolds simply because how non-erotic it is. So realism in 16-bit or 32-bit CD systems won't have the same effect. With palletization and low 240p resolution, it really hits a low point in the uncanny valley.
