midzeus.c driver
Renames game rom from invasn to invasnab & invasnv4
title changed to "Invasion - The Abductors (version 5.0)"
added version number to other games.
added notes about the latest software level as per
the Midway service bulletin
This fixes namcos1_0118u2yel, and
does a little tidying of the namcos1.c files as well. There may still
be some additional variables to reset, but this was enough to fix the
bug as reported.
* XTAL-based timing
* Correct video timing
* Full memory map
* Correct memory usage ("zero page" RAM is shared with videoram)
* Removed all input hacks
* Fixed interrupt generation
* Connected coin counters
* Added save state support
Also fixed incorrect dependency in cdrom.c.
This is an updated version of my earlier ATTR_PRINTF patch. It was
reviewed by Atari Ace to use ATTR_PRINTF properly and fixes even more
format errors. I also reviewed the whole source again and it is now
used in all possible places.
Removed ui_popup(). Drivers should always be using popmessage() instead (has been this way for a while).
Augmented popmessage() so that you can pass NULL to immediately dismiss any messages.
* fixed interrupt handling
* added support for edge-triggered interrupts on '32
* expanded interrupt support for the '32
* updated drivers using TMS3203x core to deassert interrupts
* added externally accessible functions for converting '3x floating point format
* updated gaelco3d driver to use new functions
Zeus2 (+related) updates:
* fixed save states for DCS games
* cleaned up Zeus2 waveram handling
* added Zeus2 save state support
* added preliminary model and quad rendering support for Zeus2
* added support to timekpr for the ZPRAM used on Zeus2
* hooked up ZPRAM in Zeus2 games
* hooked up controls in Zeus2 games
* updated poly.c to ensure it is idle before saving state

- video timing from schematics
- driver configuration switch Nintendo/Std Monitor
- got rid of COLORTABLE
- clocks as defines in .h
- use XTAL_*
edrandy0113gra
robocop2_0106u3gra
Converts 2 common ports to macros
Uses port_include & port_modify where needed
Added dip locations
Added DSW3 for Robocop2 (thanks to Byran McPhail)
The attached patch adjusts most conditional logging in MAME to use the
idiom "do { if (VERBOSE) logerror x; } while (0)". This has the
benefit that the compiler checks the syntax of the logging even in the
case it will be eliminated, and in fact a number of cases here needed
adjustments to compile because of this.
Here is a fix I've done to the Z80 CPU core that removes the increasing
of the R register from each IX/IY related (FD xx or DD xx) instruction.
This corrects the amount the R register should increased to to 2,
instead of 3. Documentation I've read suggests that the R register is
increased by 1 for each instruction with no prefix, and by 2 for each
instruction with a prefix (DD, FD, ED, CB, DD CB and FD CB). This fixes
some protected cassette loaders in the MESS Amstrad CPC driver, and
maybe others, which require the R register to be correct for the next
routine to be decoded correctly. I'd doubt that there is much, if any,
noticeable impact for MAME, as the R register is really only useful to a
program as a simple random number generator (or seed).
I've tested the fix with Pacman, in MAME, and when it comes across a LD
IX,xxxx or ADD IX,xx it will increase R by 2, whereas previously, it
increased R by 3.
