Blue diamond

Thank you so much! After a couple years I can play reborn again!

I tried this, but couldnt find where the backup save files are located. Is there maybe a walkthrough somewhere so I can see where to go?

I really wanna play reborn again but every time i delete and redownload it, it keeps giving me these messages. "Incompatible marshal file format(can't be read)" and "end of file reached" and then "Script 'PokemonLoad' line 461: NoMethodError occurred. Undefined method 'last save' for nil;NilClass Then it crashes and shuts down
