I've been looking all over the web for a solution for this, but I don't think there's any....
I'll ask anyway, though :P

My PS2 is unmodded and I use swap and exploit methods to play backups. I'm a big fan of the DW/SW series, but unfortunately Cash Cow Koei release mediocre expansion packs which contain features that could have been put in the original >_<

Is there a way to carry your old save to Xtreme Legends? Or is the only way to transfer your data is to use the originals?

Does anyone know about the layout of these games? For example, would the full game of Samurai Warriors be on SW: XL, just hidden? Would it be possible to "unlock" it? I guess that's thinking over the top, but :/

Many thanks
