- Added Rev. C Naomi 2 Export BIOS [The Dumping Union]
- Fixed some rom filenames that didn't fit MAME standard [Cah4e3]
New games added as GAME_NOT_WORKING
-----------------------------------
Derby Owner's Club World Edition (Rev. D) [f205v, Cah4e3]
---------------------------------------------------
Dai San Wakusei Meteor - Hau, Chack'n
Comments:
This is the initial check-in of the driver which was posted (plus some driver notes based on some quick tests). If anyone has work they need to add (discrete audio, dip/input improvements), please work with this as a base.
- full save-states support
- changed to use timekeeper-device instead of mvram + custom code
- now use timekeeper as Z80 banked RAM (verified with hardware,
now full game stats saved on power on/off as on real machine)
- graphics roms naming scheme changed as on Irgrosoft's hash-lists
for example -
http://www.igrosoft.ru/download/md5/CrazyMonkey_hash.htmlhttp://www.igrosoft.ru/download/md5/CrazyMonkey_loto_hash.htmlhttp://www.igrosoft.ru/download/md5/CrazyMonkey_ent_hash.html
because different gfx-sets not "old one" or "new one", but for
different regions.
- Roll Fruit's always-locked-coinlock bug fixed
- few old missing roms found and added:
Fruit Cocktail 030623 fcockt_3
Lucky Haunter 030804 lhaunt_2
Resident 040415 resdnt
- all known hashes added (entertainment, lottery, etc)
- misc cleanup

Details for those who are interested:
0-191: render screen
192: dummy scanline, vblank interrupt at end
193-260: vertical retrace
261: pre-render scanline
(no whatsnew)
This used a combination of clues:
- The (68k) firmware for the turtle beach wavefront card tries to fit
(scaler+1)*(preset+1) to an expected value the best it can, but limits
the scaler values to 1..31.
- The igs games use 122 for the scaler, the cave games 148. The
currently wanted frequencies at the input of the counter are around
9700Hz for igs and 6200Hz for cave. 148/122=1.21 while 9700/6200=1.56.
-> The top 3 bits may be an exponent. As it happens,
122 = 3*32 + 26
148 = 4*32 + 20
(26+1) << 3 = 216
(20+1) << 4 = 336
336/216 = 1.56
-> Once you have that, we only need to main divider.
33868800 (main clock) / 216 (igs div) / 9700 (igs expected) = 16.16
That's close enough to 16 for our expected frequencies approximations.
That gives us a post-scaler frequency of
9800Hz for igs
6300Hz for cave
And a main (cave changes the preset from time to time) in-game final frequency of
62.82051Hz for igs (measured 62.8206 at the pin of the circuit in the past)
50Hz for cave (exactly, isn't that beautiful ?)
So I'm pretty sure the final formula is correct.
I'm not sure what's left to get rid of the imperfect sound flag.

Hi
Here is a simple patch that will add a "changed by" search - it's effectively a increased and decreased search rolled into one. It is useful when you are uncertain if the value has increased by x or decreased by x so it saves having to guess which search method to try first.
