I'm unclear on the mechanics.
Cell steals Trunks time machine but instead of going back to the unseen timeline he goes back further making a new timeline.
If bulma made a new time machine would she be able to go back to the unseen timeline if she kept the date the same as before.
Or would this just create a new timeline, is the machine itself linked to the timeline, and a new one wouldn't be.
Finally. Supers anime had there be a backup CD-ROM which I assume had the settings/coordinates saved. Is there any evidence this was a toriyama idea or purely a toei one?
Do you think Bulma has any chance or has she lost access to that timeline forever?
