confusing people for far too long. Yes, this is a change in behaviour.
Add a valdiation check for ROMs with BIOS flag set that are
unselectable, fix the things it uncovers.
(nw) Fix other random stuff.

These changes work with InterPro, but haven't been tested on other machines. Despite this, I'm reasonably confident they are all correct according to the observed behaviour and the documentation.
* don't wait for REQ after initiator complete with NACK
* wait until fifo empty during dma out before command complete
* make sure drq is always cleared on bus/function complete
* reset happens immediately
* always clear TC0 when counter reloaded
* check valid commands separately for 5390 and 5390a
* handle 5390a initiator set attention command
* use logmacro for logging
the Joystick at least is needed for high score name entry.
played a bit, seems fine so...
