Fun fact: the Famicom Disk System has a Y2024 problem!
The FDS stores the disk's manufacturing/rewrite date using a binary-coded decimal year in the Shōwa era (so 1926 is year $01, 1927 is year $02, 1935 is year $10, and so on).
This means that the last year which can be expressed in this system is 2024 - Shōwa 99; which is still out of bounds for the era itself, but acceptable by the Nintendo header standard.
@asie admittedly am curious as to whether the date code is ever actually read by any software, and using hex from A0 would give us about 90 more years
@elfi@social.pixie.town you can always use illegal dates like $A0
