I took a long look at many of the games available for the PC-98. The still images in games are very, very nice. While there are some good ones (Policenauts, Farland Story series), there are several things holding back this emu:
-90% games are in Japanese
-native 640x400 resolution much too big for the gp2x
-90% of titles are hentai-related (even many good ones) and/or have Japanese weirdness. Now some may not consider this to be a bad thing, but when I'm on the bus or train it would be nice not get accusing stares for playing a game where a guy with 2 giant hammers rapes women to regain health

Overall, I think this emu would work better with a BoB, mouse support and full resolution with tv out. I also wonder if we could get most of the older games ('94 and up) to run at a decent speed, because they're the best, right?. Very interesting though.
