I haven't played for a few years, the last time I played was EP13.

 

Would the EP13 savefile even work in EP18, or do I need grab older versions and slowly work my way up to EP18. (Note that I do not wish to start over, as my savefile from EP13 has almost all available content at that point, including scanning the entire map with itemfinder.)

There have been so many changes since that point that I'm not sure it's possible.

 

I think you can skip a few episodes if you save in pokemon centers but you'd definitely have to download E13 again and figure out where you can save up to get to E18.

 

I'd also backup your current savefiles before attempting to start up new episodes that way you're not screwed.

I still have v13 on my computer, and have a backup file for every version prior; I'll try to see what happens ty
