From Varuna via GAF who in turn got it from edit edit twe via shmups, who got it from Danmaku-gata:
Apparently, Arika started porting Ketsui in 2003. They had it running perfectly outside of one section of Stage 5. This alone would put it miles above Taito's ports of Ibara and Mushihimesama. Cave gave Arika permission to release it in this state.
But, hey, it's just not good enough for Arika.
Sucks, really, since I've been wanting to play this since playing Espgaluda PS2. I had no idea Arika was officially even trying to port it.Quote:
"No matter what, we couldn't re-create the 5th stage. Sorry. You can call me a braggart, but other than that, it was 'perfect'. The problem was on the 5th stage tate-ana. No matter how hard we tried, there was deadly, warping slowdown."
