Subject: patch for state save in buggybjr
Here's a little patch for initial support of state saving in buggybjr.
(It'll help with tx1 and buggyboy too, but they are non-working)
All I did was get rid of the "anonymous" (temporary) timer that was
preventing saving, and replace it with a "permanent" timer. I didn't go
looking for data which might need to be saved.
Subject: pit8253 device
I have converted the pit8253 implementation into a device. To make it
easier to use I've also created a src/emu/devconv.h in the same style
as src/emu/memconv.h.
I do not have all roms/disk images to test all drivers. I have only
been able to test pf2012, filetto, and topgunnr.
Subject: some fix for aerfboot (bootleg of aerofgt)
this fix:
1) spriteram3 (previous value was too high and in the "city" level some build disappear
2) sprite gfx bank (previously some sprite appear right and some sprite was wrong)
3) the zoom is a litlle bit better
4) i have removed multisprite support; in the bootleg aren't present
the remaining problem is "not draw some sprite"; maybe there's a mark in some place
in the code i add, in a comment //, a way to avoid the draw of the sprite (searching a 0000 0000 0000 0000 sprite); this way works quite good but not perfectly (some time too many sprite are in the screen); maybe there's a value indicating the #number of sprite to draw (from the end to spriteram3 to start)

Subject: addendum (aerfboot)
this fix perfectly the sprite zoom
Subject: a little fix
a little update: this fix priorities in mermaid and rougien and a sprite bug:
when a sprite have x coordinate >= 0xf0 the value is negative
this fix the sprite bug
+ if (sx >= 0xf0) sx -= 256;
If seems to break Varth, hower, and has dubious effects on the boot sscreens of avsp, sfa3 and possibly other CPS2 games.
01542: 3wonders, 3wonderu, wonder3: Wrong colour of background in game selection and start screens
00410: xmcota: After a couple passes through the demo mode, the background on the qsound screen will go to a shade of green.
Subject: patch for mermaid
proper implentation of hardware collision (first implentation was incomplete)
this fix mermaid (when the player is in the water with the sharks) and rougien (Mantis 01652)
Subject: pcshare patch for mess
Another patch to machine/pcshare; this patch allows the MESS machines
to choose whether the RDY pin of the nec765 floppy controller is
connected or not.
Last weekend's pcshare keyboard was almost correct, it caused some
stuck shift key situations in MESS. This patch fixes that.
Removed a lot of MESS specific code from the machine/pcshare code.
Subject: Further ACIA changes
Added dynamic control of RX and TX pins to 6850 ACIA emulation - this is
needed for correct operation of the MPU4 Video communications system,
and may be handy for some MESS systems. To use, set the rx and tx clocks
to 0 in the acia interface, then use acia_tx_clock_in() and
acia_rx_clock_in() respectively.
Subject: Internal LAY File - Armor Attack
This is becoming kind of fun. Here's an internal LAY file for Armor Attack.
Re-created the overlay using just rectangles.
And finally got to use flipx and flipy for the first time (main reason I did it).
Subject: small change for MESS cleanup
This adds the "Machine" parameter to a MESS function call in MAME
code to go along with Machine -> machine ckeanups in MESS
Subject: Machine -> machine cleanups
This patch changes "Machine" to "machine", when the runnin-machine
parameter is already available. In some cases I could even remove the
dprecat.h.
I will look for some occurances where it can be easily changed and
afterward take a step at adding the running_machine parameter in a
few places.
Subject: rygar clocks
Corrected clocks on Rygar.
Concerning the 400khz resonator, it's genuine, not resoldered even if
schematics shows a 384khz resonator.
Another Rygar from a friend of mine has a 400khz resonator so it's
possible Tecmo had a stock of those resonators to use in change of the
384khz ones.
Subject: Minor patch submission - verbose build information for development in IDE
I am submitting this minor patch that adds verbose build information to the
build output when the "VERBOSE" flag is set to "1", rather than the simple
output normally seen, by adding the "-v" flag to the CFLAGS variable. This
is most useful for those that like to use an IDE (Eclipse in my case) for
source browsing and development. The IDE usually will parse the build
information, which is currently not available, to determine include file
locations, build definitions, etc. and will use that information to provide
more advanced navigation features.
* Fix timing of stream_update in discrete_sound_w
All sound cores update before processing changed data
* Add streeam_update to discrete_sound_r
* Now supports multiple output nodes per module.
There is the possibility to support multiple outputs per module.
In this case, NODE_XXX is the default output. Alternative outputs may
be accessed by using NODE_XXX_YY where 00<Y<08.
You may also access nodes with macros:
NODE_XXX = NODE_SUB(XXX, 0)
NODE_XXX = NODE(XXX)
NODE_XXX_YY = NODE_SUB(XXX, YY) with YY != 00
This should e.g. make discrete sound emulation easier
when dealing with e.g. flip flops (Q & QQ) and binary counters
* added sanity checks to check consistency issues introduced by this change
* modules specify number of outputs ==> Certain special modules (WAVELOG)
may no longer be used as input nodes
* removed explicit (NODE_XX + expr) from a couple of drivers
* Added plane priority to blitter - if anyone knows how this really works let us know!
- Fixes Treble Top signature writing
* Video output now supports all modes - lores, hires, mixedres, 8/7/4/3 bits/pixel
- Fixes Every Second Counts colour problems
* Added line draw
- Fixes missing stuff from Question Of Sport
* Change blitter loop type control - there are 4 types of loop.
* Corrected video frame rate to 50Hz.
* Corrected Z80 speed - 5.91mhz, this still might be wrong but I don't have a board to check.
* Accounted for Z80 cycles stolen during a blit operation. Improves gfx/sound sync and seems to fix the final round lockup in Every Second Counts.
A couple of random touchups for X, Y, and Z drivers as well.
Each driver is tested by watching the attract mode through and diff'ing logs.
My ISP was blocking mamedev e-mails for a couple of weeks, so I apologize if I did anything odd because of a discussion that I missed.
