Virgil Dupras be52fb1383 sms/vdp: fix bad mirroring
On the real machine, I ended up at some point getting a weird "bottom
mirroring" issue. It turns out that it was because when I revamped my
VDP flags in an earlier commit, I hadn't read the whole technical
notes about register $02 and falsely thought that B0 was ignored. No
it's not. When set, it mirrors the bottom 8 rows.
