I'd probably try to exchange the one rom chip in the game before exchanging either of the 2 ram chips. It sounds like it crashes before the save game would be accessed, but you could try removing the battery and see if a corrupt save game could cause it to crash.
The real question is whether all of this time is worth the time of fixing a $5 game.
