So I got a rather lovely condition copy of NBA Jam: Tournament Edition for the Genesis in the mail the other day, and the first thing I did was check to see if the save system was still working. I powered on the game, went to the saved initials list, and sure enough there were still a dozen or so saved games on the cart. Pleased that the save system was working I decided to clear out all the previous owner's saves by deleting them, then went and started my own game.
It didn't take long to realize that the cart wasn't saving my initials and records after turning it off, and a little research revealed that when there are no saves on the cart it needs to be first "initialized" by playing one full head-to-head game with the initials XXX then one full head-to-head game with the initials NBA before it will start saving your games. I followed the instructions to the letter, but every time I power off the cart all the saves (including the one for NBA, it never records a save for XXX at all) are gone.
Now clearly the previous owner was able to save their games just fine, but it seems that by deleting the original XXX and NBA initial save files I may have inadvertently killed the cart's ability to save games. Is there any way to fix this or have I just permanently bricked the cart's ability to save by deleting those original XXX and NBA save files? Any advice would be greatly appreciated!
