225260ba40 sound: fix ym2612 address handling 
I already fixed this back in 2017 with
151df6adf9, but forgot about
ym2612_write_local(). Fixes missing sounds in Overdrive2.

04cb5a192d carthw: more accurate x-in-1 pirate handling 
There is no A0 so it should be masked out. Even though the cart could
use use LWR as A0, it's not actually connected as seen here:

3314e88244 readme: make it more neutral 
I'd like the readme to not look weird in notaz/picodrive when I merge
all the changes, where it will be unclear who the 1st person pronoun
refers to. Several people have put quite some effort into it, so I think
it's best not to highlight anyone.

Also remove the old readme which has become outdated.
