Ok, so some good news...
After fiddling around with a rip of tokimeki and magic engine for some time, I was able to extract the actual save file that unlocked these shooters, and create an iso image of nanami so you can write this save data to your real PCE backup memory. (Holy f*ck, manually typing in ~100 lines of hex data -- not so fun!) So now you can play this thing on the real hardware right away without having to suffer through the whole dating sim & trying to unlock the games.
I must say it's pretty damn impressive. By far the most impressive mini-game I've seen to date (I know that's not saying _too_ much, but Force Gear really could've been an excellent stand-alone game.)
Here's what you need to do:
1) Download the ISO here --
http://www.savefile.com/files/15669102) Burn the ISO. I used Nero, but I suppose whatever works.
3) Put the disc in your player, and on the menu, select "Restore a file".
4) Select the tokimeki file (disregard the "beast3" file, that's my end save file for KO Beast), and write it to your backup ram.
5) Then boot up the actual game, and on the title menu, select Option (オプション)
6) On the option menu, select Omake (おまけ)
7) And now you're playing on the real hardware, cause emulators are for lamers!
I guess I gotta go and get the real copy of the game now. Never really thought I'd be hunting this game down, as I have the SS version, and didn't really care for it so much.
BTW, that ISO file will be gone after 30 days of inactivity, so anyone thinks it's important enough, please host it somewhere more permanent.
