Subject: to simplify cischeat inputs
Hi,
the enclosed diff has a twofold effect on cischeat.c:
on one side: it adds diplocations to bigrun, scudhamm,
cischeat & f1gpstar
on the other side: it removes the current hacky handling of
f1gpstar coinage dips (check video/cischeat.c to see what I
mean with hacky!) to use conditional ports instead. BUT in
order to do this, I had to add more possible values for the
PORTCOND in iptport.c. The problem is that f1gpstar has a set
of coinage settings when you set the region to JPN or USA and
another one when you set the region to EUR or FRA. To implement
this I added the following self-explanatory new PORTCOND:
ISLARGER (>), ISNOTLARGER (<=), ISSMALLER (<), ISNOTSMALLER (<=).
Only two were really needed to implement f1gpstar dips, but
the other two seemed costless to me while offering even more
flexibility to the PORT_CONDITION macro.
Also notice that the handling of conditional ports in 'TAB>Dip
Switches' menu doesn't work well (in the current source, not
affected by my patch) with contracted expressions like
PORT_DIPUNKNOWN_DIPLOC: the wrong items remain listed in the
UI menu even when you change the condition! If you leave the
DEF_STR( Unknown ) with ON/OFF cases, everything is displayed
correctly in the menu. However, I was not able to track down
what part of code is responsible for this bug.

Subject: another small fix
Hi,
with this last patch I hope to have fixed all regressions I could
had introduced with my past submissions. This time it was a small
problem due to my fix to bug 1565 (alleymas duplicated inputs):
the game was unplayable in u3 (even if not reported to MT).
Regards,

Subject: fix for MT bug 2056
I failed to see this wrong tag for almost 2 days!! One would guess that
looking for the cause of coins problems, an handler with the comment "coin
inputs" should have been noticed immediately. I saw it only this morning :(
However, fix in attachment.
Regards,
Fabio Priuli

Subject: let's say goodbye to untagged input ports ;)
Hi,
enclosed please find a few patches against 126u3 source
* port01.diff -> port09.diff : these patches continues the
cleanup of inputs in drivers starting with C (the remaining ones),
D and E. No ambiguous situations this time, so I guess there should
be no problem with the changes. Improvements include conditional dips
added to dynduke and diplocations for chinagat, chqflag, circus,
citycon, cloak, contra and dynduke
* tag01.diff -> tag09.diff : these patches add tag to EVERY input port
in drivers starting with F->Z. Notice that only tags are added, no
AM_READ_PORT, nor PORT_INCLUDE (and I saw a lot of drivers would need
it ;) ), nor other cleanups contained in the patches above. I'll keep
cleaning input next week, probably, but at least we can definitely
remove the untagged version of PORT_START :) Notice I was able to
compile the source commenting out the definition of PORT_START, so
I guess every occurrence is covered...
- new tag <comment> (within <cheat>) is read and preserved
when saved
- removed variable attribute from <parameter>; it is now
assumed to be 'param'
- added default attribute for <parameter>
Added new variable 'frame' accessible from cheat scripts. This
can be used in the conditional to prevent execution on every
frame, or for other effects (like displaying temporary messages).
Added new variable 'argindex' which is the index when processing
an <argument> with a count attribute greater than 1. Can be used
in expressions like:
<argument count="3">main.pb@(1000+argindex)</argument>
Reinstated the cheat menu. It now displays all loaded cheats and
allows for them to be activated. All known cheat behaviors should
be working now.
* moved a couple of exp(x) from _step into _reset where appropriate
* use tabulated function values for the transfer function in DSS_INVERTER_OSC
==> 40% speed increase in dkong - from 520% to

Average speed: 722.48% (29 seconds)
tool which walks through either an AVI or CHD capture from a
laserdisc and ensures that there are no anomalies lurking in
the VBI data.
Added new option to chdman, where if you use -createav with
a special filename (either 2:2 or 3:2) it will create a fake
laserdisc files with the equivalent cadence. This can be used
for testing until full captures are available. Most games used
2:2 apart from Dragon's Lair and Space Ace, which were 3:2.
Note that even though these files are essentially blank, they
are Huffman-compressed, meaning that the maximum compression
ratio you will get is 8:1, so they still end up ~5GB.
Moved error strings from chdman.c to chd.c, where they can be
fetched from any caller via the new chd_error_string()
function.
Updated vbiparse to improve Manchester code decoding. It now
assigns a confidence level per bit based on how solid the
data is. Also added a new function vbi_parse_all which parses
the white flag and all three lines of metadata from a
laserdisc frame. It then compares line 17 and 18 against each
other and selects the most likely candidate based on per-bit
confidence and other factors.
Added frame number display to laserdsc.c. It is off by
default, though most players can be configured to turn it on
(not sure if any actually do). It can be manually toggled via
the backslash key during playback.
Commander (MACH 3 hardware). Old laserdisc hacks are now removed.
The code now talks to the standard Pioneer PR-8210 interface. Also
removed hacky "target list" from the MACH 3 ROMs; this information
is now decoded on the fly from the right channel laserdisc audio.
Other Gottlieb cleanups:
- moved sound inputs to audio/gottlieb and included them in
all relevant drivers
- ordered input ports and ROM definitions consistently
Other laserdisc changes:
- changed PR-8210 interface to work consistently for both Gottlieb
and Stern games
- added audio callback mechanism to allow drivers to peek at the
raw audio streams
- extended the VBI parser to be even more lenient
