Slowbeef (the Youtuber guy you may or may not have heard about) has been working on and off on a PC-98 port of this game, but I don't know how far along he is. You'd have to ask him about it probably. VNs are sadly the hardest to translate, because of the amount of text. This especially pertains to the ones for older, more obscure systems. Well, sometimes RPGs are worse I guess, due to all the menus.
Some projects are relatively easy - like the PCE HuCard games we did (War of the Dead, Out Live, Gai Flame etc.) PCE-CD games are considerably more difficult to work on, which is likely why you almost never see fan-translations for it - most of the translation groups are very Nintendo-centric anyway. By that I mean, there aren't any PCE-dedicated groups, like AGTP in the case of SNES. Anyhow, I hope either slowbeef or someone else finishes this game at some point. The PC-98 version would likely be easier to hack. One person made a translated walkthrough of it on YT, too (don't remember if he finished it or not) -
. That's the best you're gonna get for now, I think.
