custom roster in dynasty

how would i convert an already made roster, take it, and put it in dynasty mode. ive tried some file converting but the save type keeps coming up as a roster. any help would be great.

Don't overwrite the save.dat file when you're overwriting files in the Dynasty save folder; I'd say that's what's causing the problem.

whenever i sim it crashes...any help?

Are any error messages displayed when the game crashes?

none whatsoever
