no idea, but on 2ch it's reported to work on CycloDS 1.56B3, and not to work on R4, EDGE, DSTTi, and DSTT ( link)

edit: found bug on R4 1.18 with unpatched: able to start a new game and save, but when you quit the game and try to reload the save, it deletes itself (considered as corrupted I suppose ...).
