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)
in no universe is this a working system ;-) (nw)
Some mame.mak file cleanups/consolidations - adding a couple items mistakenly left out. (nw)
make the orlegend111t set work [iq_132]
added 315-5296 device
gts80.c : added original 'sound-only' card.
Some mess.mak file cleanups/consolidations  (nw)
(MESS) maria.c: improved DMA accuracy. [Mike Saarna, Robert Tuccitto]
  - Last Line DMA value corrected to 6. GCC and Atari docs both show a 
    difference between Other Line and Last Line as +6 at the lowest part 
    of the range.
  - Blank scanlines are drawn when DMA is off, like real hardware.
  - If MARIA hits the DMA limit, the CPU doesn't run until the next 
    scanline.
chqflag.c: improve k007232 volume/pan controls, still largely guesswork [Alex Jackson]
(MESS) vic20: Emulated the Final Expansion 3 cartridge (only RAM/FlashROM supported). [Curt Coder]
Fixed compile. (nw)
wecleman.c: add missing k007232 volume callback [Alex Jackson]
(MESS) vic20: Added CPLD image to Final Expansion 3. (nw)
gts80 : placeholders
new clones
Chelnov - Atomic Runner (Japan, bootleg with SCM8031HCCN40) [Jan Kretschmer]

Bryan forwarded this to me last year, forgot all about it until I just did a bit of a clearout of old mails.  Program etc. is the same as the regular Japan set, but it has a 8031 MCU in place of the usual 8051 and the dump includes the ROM for that.  I haven't currently hooked it up so it still uses the simulation at the moment.
