you just right click on the 'states' screen with that save displayed in the box and click 'load' (you must have already loaded a game and be on the field or world map)
but dlpb says you can actually skip straight to the credits with ochu, although probably requires one of the more advanced functions of it that i havent used, might just need to read the help file that comes with it - i havent done that either so dont feel bad
edit: the file goes in data/save not just data, sorry
