You'll have to be a bit more specific than that. What kind of buffers are you talking about? There are quite a few 74 series ICs that act as buffers 74244 and 74245 to start with as well as less commonly used ones.

Have you got a picture or the markings off the IC?

Ok finally found my glasses and some good light, It is a zero gunner 2 cart. there are 9 chips on the two connector side of the cart. Im assuming that those are the buffer chips? There are two types of chips within those nine. If i get a error 01, I would have to replace all 9?

5x LCX16245G

According to Andy Error 1 has nought to do with the buffer chips mate. What exactly is wrong with the cart?

I may of mixed up the error but i know the cart has been run above 5.2V.

Yes, Error 01 can be caused by those pesky buffers...

Replace all of 'em.

I get so confused with the advice on this :lol:

One expert says:
if the buffers had gone the game would not function at all - error 02.
and another error 1. Flipping Naomi's... :crazy:
