So I went to check my download list on my PSTV and I saw that the PS1 Classic Magical Drop F was back in my download list. A couple of years ago Magical Drop F was completely removed from the PS store including being removed from peoples download list even if they had bought it. (Come sort of licensing issue probably?) The only way to play the downloadable version is if you already had downloaded it. Well now it's back so if you have bought it before you can now download it again.
I'm not sure if it's available for purchase but if you don't own it and see it on the PS store let me know.
