I'm most familiar with the save files on the other forum, specifically Pato's: http://www.laxiusgames.org/phpbb3/viewt ... =68&t=4212
(It's a compilation of save files. You'd have to download them all, but you would only actually need save07.rxdata)
It's incredibly high end on the item collection rate, character levels, and money. It can lag some computers though, because it just has so much stuff packed in it. :P
There are other save files out there, but I don't recall that most of the other ones did a very good job of explaining what items/quests they found/completed, so I can't say much about them.
Maybe someone here might have a save file that is a little more down to earth though. I'd like to see another 99% completion of LF1 save file without every character at levels 80+ personally. Regardless, whatever save file you do end up going with, just put it in the exact folder as listed above and LF2 should pick up on it for import.
