That would be wonderful! There are a lot of different versions with all kinds of extensions. A cool thing about The Tower II (a later version of Yoot Tower only released in Japan) is the ability to plug in new content, using "Tower Kit"! So it should be possible to reverse engineer its plug-in system, and plug new stuff into it, or even create a plugin adaptor so you can easily create plugins in JavaScript / HTML / etc.

"Tower Kit" was released, but I haven't been able to find an archive of the executable, just some web pages about it:

There's even a monster movie version of "The Tower II Special Gamera Pack" released with “Gamera 3: Revenge of the Iris”!
