Untangled Little Robin sound HW from video timings [Angelo Salese]
(MESS) abc806: Video and save state cleanup. (nw)
Some changes/corrections to device descriptions from MASH (nw)
Fixed a long standing bug in tempest by specifying quantum perfect emulation. All save states should be removed since they may contain a corrupted game state. [Couriersud]

Additional notes:

Actually, the routine at AE1C is called after high score entry resp. after the high score screen was displayed. It has something like

lda 60ca
ldy 60ca

and expects the high nibble of "A" to match the low level of "Y", i.e. that 4 shifts occur.
(mess) pc: cga cyrillic
h63484: added other 2 commands used by fashiong. (nw)
