How to increase max number of game saves on PS3?

You mean you have 130 different saves for 1 game? all in the Save data section of the PS3. Why do you have sooooo many game saves overwriting the data isn't really that big of a deal. If you want to increase this try getting an external HDD to copy save data to then delete the data from the PS3, you will still have it on your external drive and can copy it back to the PS3 when you want to.
