Yeah, no other option but VGA for me too sadly. I really hope somebody can figure this out. Maybe I need to message Japanese-Cake and see if he could work his magic like he did with hacking the other non-VGA games?
@mrnobody: I'm afraid, I'll be the one commenting on the quality of the video cutscenes. The little that I've seen (i.e. the opening sequence) has been hard to watch, since it's full of MPEG compression artifacts. Did you use the original GD files for adding the subtitles? Just in case you're missing these, let me know. I might be able to help you out.
I've been hoping someone can make a VGA patch for this. I remember trying this game years and years ago back when I still had a CRT. The idea of co op survival horror seemed great. My friend and I stumbled through it quite a bit at that time.
Now it's finally in English but VGA/HDMI is the only way I can play now. I'll keep hoping.
