trident: reworked Bresenham line drawing.  It's better, but I'm still not convinced it's completely accurate.
gts80.c : WIP
whoops III (and hopefully last). nw.
a few more generic cart slots. nw.
and one more. nw.
Some minor mame.mak cleanup.  (nw)


Comments:  I eventually will be consolidating more of these bits and attaching them to their proper driver.
new clones
Arkanoid (Japan) [ShouTime]

(doesn't work, MCU isn't dumped.)
atarisy4.c: converted from polylgcy.h to poly.h (nw)
added handcrafted MCU rom with corrected level table pointer data for the new set to make it work (nw)

note, I think the handcrafted data in arkanoidja has a bad value when compared to the other sets?
change note (nw)
new clones
Raiden II (Raiden DX hardware)
Raiden DX (China, Ideal International Development Corp license)

(just some old sets that were dumped years ago and never added)
some more generic cart slots. nw.
removed this duplicate sketch
misc additions (nw)
from rtw (nw)
apparently R2 collisions are more correct like this - it should be possible to pass through the 2nd boss 'straight' attack with a fully powered up ship.

(it's also more consistent with collisions in r2dx_v33 where you can - that does collisions in software)
