So I'm working on a Sega Hang On. On the self-test, it fails RAM check IC 74. If it really is that IC, it seems to be a Fujitsu MB8484-15L 8kx8 RAM.

And of course it's soldered on the board.

Now the game seems to play great, and my time is pretty limited now...

I don't know if that RAM location points to some video memory or something where I wouldn't notice an error on one bit or what...

I'm curious...

What's the chance that IC 74 is really bad (as opposed to the cap next to it or some other part).

And if the game plays great, do I really even need to worry about it?
