Link to the original article here but I'm also going to explain it.
In summary, in a recent Touhou livestream commentated by ZUN and BeatMario (part of the doujin circle Cool&Create), the two started talking about the PC-98 Touhou games and BeatMario suggested they could be brought to Mini Console (think something like NES Mini or Genesis Mini). To this ZUN responded that maybe Naoki Horii, who is president of the company M2 and also is a huge Touhou fan, might be willing to do it.
M2 are a company responsible for handling the emulation for many re-releases of old games for newer hardware, including titles for Sega Ages and the Nintendo Virtual Console - and they also worked on the PC-Engine Mini with Konami, which released recently in Japan.
Now, from my understanding this was mostly just banter between ZUN and BeatMario, but then something else happened - after someone transcribed the conversation and put it on Twitter, Naoki Horii responded to the transcript, saying "I'll say it right now, I'll do it".
Of course, it actually happening is much more complicated than this - this hardly "Confirms" anything - but it does show there is interest. The idea of a PC-98 Mini is certainly interesting. Like nearly all things Touhou, it probably wouldn't leave Japan, and even if you imported it I can't imagine it would be possible to run translation patches on it, however given that running an emulator uses a lot of processing power and can cause the game to be choppy if your computer isn't that powerful (my laptop certainly can't run the PC-98 games that well), having a dedicated system for it sounds appealing. Anyways, what do you think about this?
