Mame 81u4 Released

[James]

http://haze.mame.net/

 

What's New:

 

0.81u4

 

General Source Changes

 

Hyperstone CPU core fixes [Pierpaolo Prazzoli]

- Added addressing of next byte if in load / store instructions using

Displacement Address Mode PC is used as register destination

- Added local registers wrap around modulo 64

- Added trap instructions to the dasm

- Added some debug info when high global registers are written

- Fixed some wrong format in the dasm

- Changed reset to act as an exception, as the doc claims (before it crashed

if reset was used as an exception)

 

Killer Instinct Fixes [Aaron Giles]

* cleaned up memory maps

* found second bitmap page, fixing a bunch of video problems and romoving

the egregious hack I had in there before

* fixed sound reset and initialization

* all diagnostics pass

* fixed coinage dipswitches

* added 2 alternate ROM sets for each game

Fixes: kinst067gre2, kinst072gre

 

MIPS DRC fixes [Aaron Giles]

Fixes an edge case where a memory access like:

lw r3,$0(r0)

would leave the stack in a funny state and lead to a crash.

Fixes kinst067red.

 

Instructions of the form:

ld r10,0(r10)

Would load the low word into r10 first, and then use the modified r10 (plus

4) as the address of the high word. Bad bad bad.

Fixes the sky graphics in several of the kinst2 levels.

 

ZN Improvements [smf]

24-bit rendering support for Judge Dredd

 

Updates to the 'jalmah' driver [Angelo Salese]

kakumei and kakumei2 now boot but neither are playable due to protection

 

Misc Updates [Nathan Woods]

src/windows/windows.mak:

- Fixes the afore mentioned problem with x86drc.c

 

src/fileio.c:

src/windows/fileio.c:

- Adds in a new (windows only) mode for opening files whereby files

can be opened for read/write, but changes are not actually not written

to the original file but rather to a temporary file. This trick is used

by the MESS testing facility so that tests do not mutate the images they

operate on.

- Small cleanups

 

src/png.c:

- Replaces a #ifdef MESS/#else/#endif combo with a usage of the

APPNAME macro

 

SPI / 386 updates [Ville Linde]

* raidnfgt now runs normally and correctly through

attract mode and gameplay, modulo the encrypted

graphics. Still kinda mesmerizing

* viperp1 starts to boot now, but doesn't get very far

* Hooked up the Z80 bankswitching, so sound started

playing in some games (notably Raiden Fighters). (R.Belmont)

 

Various ST-V updates [Mariusz Wojcieszek]

fixes sprites in groovef which is now playable, adds some RBG0 scrolling

which greatly improves background graphics in cotton2, cottonbm, grdforce

and othellos

 

Debugger Fixes [Aaron Giles]

This is a quick attempt to make the debugger more useable with the new

memory system. The masking of addresses and data should now be working

properly again.

 

Also, you can go to any memory window and type 'P' to view program address

space, or 'T' to view data address space.

 

OSD 'NO EXECUTE' Support [Aaron Giles]

This patch introduces two new OSD functions:

 

osd_alloc_executable();

osd_free_executable();

 

For most platforms, these can just map to malloc and free. However, starting

with WinXP SP2, if you are running on a processor that supports the

NO_EXECUTE bit (currently only 64-bit AMD chips),

standard user-mode memory allocations won't allow you to put code in them

and execute it.

 

Since this is exactly what x86drc.c does, I've added the two functions

above. On Windows, these map to calling VirtualAlloc and VirtualFree, which

allow you to specify the read/write/execute states of the pages thus

allocated.

 

Lethal Justice / Egg Venture Cleanups [Aaron Giles]

* merged memory maps

* fixed video size in Egg Venture to correct flicker

* switched to VIDEO_RGB_DIRECT

* removed unnecessary ROM regions and memcpy'ing

 

Rockola Cleanups / Fixes [Curt Coder]

* Fantasy/Nibbler/Pioneer Balloon

drivers/rockola.c

sndhrdw/rockola.c

- Correct CPU frequency from schematics

- Hooked up SN76477 sound for BOMB effect

- Merged memory maps

- Cleaned up driver a bit

- Fixed dips

- Enabled debug inputs
