continue saved game w/R4 for Them Park cant do it

hello, i was playing them park for some time and saved the game from the game play option, i see the .sav file there but i can t continue the game i have to start all over, any ideas how to continue the game?

 

did you rename the ROM? the save file must have exactly the same filename as the ROM.

 

Try updating to the latest firmware and delete the old .sav.

 

try updating both the m3 and r4 need to be updated to play some games
