Arbee's (R. Belmont) MAME WIP Update!

By Alpha, October 7, 2005

Arbee, better known as R. Belmont, has posted another update to his MAME WIP page.

Now hear this

Ace Driver is the only (Super) System 22 game without sound in current MAME. This is completely correct. It was not “something I missed” and I did not do it to fark with people. The data in that ROM is incompatible with the Prop Cycle BIOS for whatever reason (there’s a chance it could be triggering an M37710 opcode bug, but that seems fairly unlikely at this point) and MAME will crash if you attempt to hook it up.

Rebirth of DSEmu!

By Alpha, October 7, 2005

Two9A has informed us here that he has finally decided to continue the project for DSEmu!

It would seem that the project lives once again. I took up the idea recently of using C++ to create a massively modular plugin structure, and it seems to be pulling itself off. As of right now, I have a small amount of an ARM7 core in one plugin, a mode3/4 GPU in another plugin, and a memory plugin tying them together.

Not only that, but the whole lot is portable cross-platform, thanks to the FLTK user interface plugin. And that means I can run this thing on Windows, Linux, yea even on OSX (if it would compile there).

As of right now, the simplest of mode3 demos run, and mic's afire also seems to work fine. Anything else refuses to output. That may be due to missing instructions in the core, or missing graphics; either way, there's a long way to go.

I am, of course, providing the source. Eventually, this'll make its way into the official DSemu repository as a (huge) patch, replacing nigh-on the whole repository with new source files. But for now, you can grab the source at the link below. (You will need fltk's includes and libraries; the Unix makefile checks for them, the Windows one doesn't.)

Nestopia v1.20 released!

By Robert, October 7, 2005

Some of the new features:

* DirectDraw kicked out and replaced by Direct3D (DirectX 9.0c now required)
* More video filtering options
* More multitasking friendly
* Configurable menu keys
* Less cumbersome to take screenshots and no more GDI+ requirement
* Selectable auto-fire speed
* Recent directories
* Ability to lock and clear the recent files and directories lists
* Selectable LED source for FDS disk access
* Alternative emulation speed via assignable key/button
* Ability to change the menu color
* Changes to brightness/saturation/hue takes effect immediately
* More logfile (disabled by default now) diagnostics
* Cursor gets auto-hidden
* Many hard-coded strings now moved into the resource section
* Image info for FDS and NSF files
* Can make IPS files out of changes to FDS disk files
* Can edit iNes file headers
* Hq2x/Hq3x filter support
* Additional GUI improvements

New iNes mappers:

53, 56, 142, 158, 164, 165, 193, 203, 204, 205, 206, 207, 208, 209, 210, 211, 212, 213, 215, 217

Fixed iNes mappers:

*many*

New UNIF boards:

Mario 1 Malee 2, Novel Diamond 9999999-in-1, Super Game 8237, Super 24-in-1, WS 40-in-1

New controllers:

Oeka Kids Tablet, Hyper Shot, Crazy Climber, Mahjong, Exciting Boxing, Top Rider, Pokkun Moguraa

Other emu core related things:

* More standard conformant C++ code
* Easier to port to other platforms using a new written API
* Many speed optimizations (but at NO cost of emulation accuracy)
* Save state and movie file formats rewritten, old files will no longer work
* More accurate APU and PPU emulation thanks to RE work by Blargg, Kevtris and Quietust
* Perfectly time-aligned sound sample output by using a common clocking rate
* Uses new updated palette by Matrixz
* Better (but not perfect) NTSC color generation algorithm based on tweaks by AWJ
* ROM database fixes and additions
* Support for phantom stereo sound output
* More accurate FDS emulation
* Better sound quality with the external sound chips
* Auto-selects between Famicom and NES 4-player adapter based on game CRC
* More accurate emulation for several controllers
* More accurate hard/soft reset behaviour

MAME v0.100u4

By iq_132, October 6, 2005

0.100u4
-------

MAMETesters Bugs Fixed
----------------------
acrobatm0100u3gra [Mamesick]

Source Changes
--------------
More NSS updates. This is mostly for MESS's benefit but nss_ncaa improves
from it too. [R. Belmont]
* SPC700: Fixed operand order for SBC to memory
* SNESHW: Implemented unknown DMA & HDMA modes
* SNESHW: Fixed SRAM sizing (used as protection in some games)
* SNESHW: Boosted interleave
* Fixed scroll registers to work like real hardware
* Fixed timing of OAM address reset and range/time over reset to better
match real hardware
* Fixed missing "break" for HDMA mode 5
* Fixed behavior of OLDJOYx registers when auto-read is enabled

Added filters back into the Scramble driver. [Hans Andersson]

Changed break/watchpoints in the new debugger to display in hex.
[Anonymous]

Updated usrintrf.c to work better with MESS. [Nathan Woods]

Merged ctribe machine driver with ddragon3. [Mamesick]

Improved Zip & Zap DIP switches. [brian Troha]

Improved Egg Hunt DIP switches. [brian Troha]

Fixed flipscreen in TC0100, which improves Liquid Kids. [bryan McPhail]

Improved Metal Saver DIP switches. [brian Troha]

Cleaned up merging of Jolly Card sets. [Roberta Fresca]

Updated 65816 and 37710 cores: [R. Belmont]
* Fixed both CPUs to set the data bank register to the destination on
an MVN/MVP
* Some minor tweeks so the debugger works properly when the 65816 is
executing out of a read handler (as it always is for the SNES)

Filled in missing asteroids DIP switches. [Kevin Jonas]

Updates to the I386 core: [Ville Linde]
* Added i486, Pentium and Cyrix MediaGX CPUs
* Replaced the opcode tables with a dynamically built one
* Rewrote the cycle counting to support different CPUs
* Added page translation
* Tons of bugfixes
Also updated the SPI driver to work with these changes.

Cleaned up the taito_f2 driver: [brian Troha]
* Converted what I could to port_include and port_modify
* Fixed a few rom names and standardized names add a PCB layout.
* Changed the sound CPU to 240000/6 and the YM2610 to 240000/3 as there
is no 16MHz OSC on the PCB. Only a 26.686 & 24.000 MHz chips.

Fixed inputs in vliner: [Mamesick]

Added some basic zooming support to the gstriker/twcup94 driver.
[David Haywood]

Improved accuracy of joystick types reported in -listxml. [buddabing]

Added "Uptime" to the bookkeeping info displayed in the UI. [Aaron Giles]

Added new driver flag: GAME_SUPPORTS_SAVE, to indicate drivers which have
save state support that is supposed to work. Attempting to save state on
a game without this flag will give a warning. Save state-related bugs may be
filed against drivers with this flag set. [Aaron Giles]

Removed the GAMEX and GAMEBX macros. The flags parameter has been moved into
the GAME and GAMEB macros and these are used for all games. [Aaron Giles]

Converted a few more drivers over to using the new memory_configure_bank
calls. [Aaron Giles]

Added save state support to the Cinematronics vector sound hardware and to
the Z80 CTC system. Also fixed QB3 banking when used with save states.
Marked all the games in cinemat.c with GAME_SUPPORTS_SAVE.
[Aaron Giles]

Added save state support to the TMS5220 chip. Added missing registers to
the 6800 core's save state. Cleaned up 6821 PIA initialization and save
state registration. Marked all the games in mcr.c with GAME_SUPPORTS_SAVE.
[Aaron Giles]

Changed ui_popup to display longer by default for longer messages.
[Aaron Giles]

Added new option -autosave which automatically loads a game at startup and
saves it at exit time for any game which is explicitly marked with
GAME_SUPPORTS_SAVE. For other games, this option has no effect. [Aaron Giles]
