I downloaded RMXP today and started making my game, then when i wanted to save in the game i noticed there were only 4 save states. can somebody please help me

I don't get it... You want to increase the save slots???

There are some scripts that you can use to increase the number of save slots. There are also auto-save scripts and the like. Doing a very simple search or looking in the scripts section of this site will yield what you are looking for (I believe).

what i meant was, it had 4 save slots instead of 15, but tnx for the advice
