Ys vs. Sora no Kiseki: Alternative Saga

A cross-over using Ys Seven engine, between the Trails in the Sky, and the YS series, both from Falcom. Oh, and Adol can talk for the first time!

Anti-Piracy
If you play a pirated version, collision detection for walls and some floors would randomly be turned off, resulting in your character clipping through walls and going off-bounds before respawning again on their starting location. The same can happen for some bosses or enemies, rendering some fights unwinnable. It's possible, but tricky, however, to finish the game despite these "bugs" showing up.
