Nick44 | 1 Posted August 9, 2022 Share Posted August 9, 2022 I've recently been made aware from acidjaguar the variations on these stamps. 00-11 some with software revisions A . Picture is from sticker/test release ballon fight has no stamps. Purpose for thread is to attempt to find out how to correctly replace/upgrade cart backs for grading . 1 Link to comment Share on other sites More sharing options...

DefaultGen | 5,425 Posted August 11, 2022 Share Posted August 11, 2022 I don’t know if there’s a great source for pairing stamps correctly for games that have numerous revisions. The same variant of Super Mario Bros. cart for example can have different stamps that may only pair correctly depending on the PCB variant in the cart, which is some of the worst documented NES info there is. More public research is needed in this area but since it’s nerd CIB stuff rather than get rich quick stuff it’s not very sexy. Link to comment Share on other sites More sharing options...
