Ys vs. Sora no Kiseki: Alternative Saga is a crossover between Trails in the Sky and the Ys series, using the Ys Seven engine. Oh, and Adol can talk for the first time in many years!

Initially released only in Japan, a remastered version titled Ys vs. Trails in the Sky: Alternative Saga is scheduled for worldwide release in 2025 for PS4, PS5, Switch and PC.

To do: Two test maps remain in the game (testmap and mp_9999), as well as a debug menu in /PSP_GAME/USRDIR/script/test.bin

Cut Content

Located in /PSP_GAME/USRDIR/system/, are a few plain text files, they contain some commented out code that may hint at some cut features.

The File Mainmenu.xml makes references to modes not present in the final game, such as "SURVIVAL" and "MINIGAME".

The file for the button configuration menu also has some removed entries,

The first one サポートキャラ is captioned "サポートキャラを呼び出すボタンを設定します", and that appears to be an option to call in a support character.

This file also has two other removed options, 決定 and キャンセル. These would have allowed you to remap the Confirm and Cancel buttons.

Development Leftovers

Present in /PSP_GAME/USRDIR/script/ are plaintext versions for all the game scripts. These .scp files are not run directly by the game, instead the bin files of the same name are used.

Here's an example showing the first event in Estelle's story:

Anti-Piracy

This game runs a check to make sure it is being run on official firmware, aside from the game requiring 6.20 firmware. If this check fails, collision detection for walls and some floors will be turned off in a level, resulting in characters clipping through walls and/or going out of bounds before respawning back to the starting location. In addition, some bosses or enemies won't respawn back to their starting location, rendering some fights unwinnable.

It's possible, but tricky, to finish the game despite these "bugs" showing up.
