Commodore Plus/4 and C-16 emulator

Just a quick release before my life's greatest emulator project kicks in. This version adds preliminary support for some effects that double the vertical resolution of the plus/4 by scanline interleaving. While the effect itself has been considered possible since around 1993, it has not been explored further until recently. Here's the - very short - list of changes:

 

* support for true interlace

* more new icons from Chronos

* couple of bugfixes

 

Obviously, true interlace will only work properly on the 'Very high accuracy' emulation level and in double sized window modes.

BBC emulator

Version 3.81 (Mike Wyatt, Jon Welch)

------------

* Added -DisMenu command line option to disable the menus.

* Fixed issue where sound output stops after about 10 mins.

* Corrected the fix in v3.8 for sound artifacts. Sampled sound works correctly again.

* Added periodic noise emulation tweak from Rich Talbot-Watkins.

* Updated instructions for defining user keyboard mappings (thanks to Jonathan Bluestone).

* Bug fix - Cursor position wrong when in column 1 in editing mode.

Source Changes

-----------------------------

Swinging Singles cleanup: [Tomasz Slanina]

- hooked up crt6845

- converted to tilemaps

- simplified protection(?) emulation

- removed tilemap, a bit more low level video hw emulation

- fake colors

 

Lowerd FPS in lasso.c to avoid corrupting Chameleon's high score table. [Zsolt Vasvari]

 

Removed obsolete uitext.c and all references to it. [Aaron Giles]

 

Some more modernization/clean-up in the exidy driver. [Zsolt Vasvari]

 

Added VIDEO_ALWAYS_UPDATED for reliable collision detection in the CVS driver. [Zsolt Vasvari]

 

Cleaned up astinvad driver: [Aaron Giles]

* Proper video timing

* Hooked up 8255 PPIs

* Correct interrupt timing

* Consolidated code into single file

 

i8039.c/mario.c updates: [couriersud]

* fixed movd instructions

* add MB8884 and M58715 cpu types

* moved timer hack to M58715

* added ram_mask for internal ram access

* added R.A11 as 'M' to dasm flags

* added EA "IO" port

* mario now uses M58715 as sound cpu

* hooked up EA line for M58715

* fixed portA startup value

* documented hardware changes to use a I8039 on a mario board

 

sauro.c: [couriersud]

* revert promsize to 256 for trckydoc

 

Added XTAL clocks to zaxxon.c. [Aaron Giles]

 

Cleaned up cojag/jaguar driver: [Aaron Giles]

* proper video timing, configured by the chipset

* 32-bit rendering, removing 16bpp hacks

* support for borders

* proper object processor timing, including multiple passes per line

* added R3041 as a clone of the R3000

* fixed XTALs based on documentation

 

Consolidated exidy and victory drivers. Removed complicated dirty tracking from victory.c. Reorganized the exidy audio hardware code. Changed Targ to use a loaded PROM instead of a hard-coded one. Renamed Side Trak to Side Track as per the title screen. [Zsolt Vasvari]

 

6821 PIA changes: [Zsolt Vasvari]

- Added orthogonal accessors

- Removed hacky update_shared_irq_handler(), now the same IRQ callback maybe called multiple times, but this shouldn't be a problem

- IRQ lines are cleared on a reset

 

Disabled code in the TMS5220 that set the Buffer Empty flag after a stop frame. This fixes Victory. This might be the incorrect fix but the old code wasn't working either. [Zsolt Vasvari]

 

Hooked up revx dcs reset line. Signaled IRQ on correct CPU when DCS sends data back (duh). [Aaron Giles]

 

Removed unnecessary check that could cause SCSP hangs in grdforce. [kingshriek]

 

Tweaked deco156 clock speed to be 28 to prevent the games from running in slow motion. I suspect the 156 chip has an internal multiplier, the usual input pin is 7Mhz IIRC. [David Haywood]

 

dkong.c changes: [couriersud]

* added equivalence circuit for Sanyo EZV audio amplifier

* Set DK_C159 = 0 to avoid over-aggressive high-pass filter. Solely based on observations.

* added comment on above to source

* Added define DK_NO_FILTERS to turn of DAC filters and post-mixer filters for debugging

 

Adds dips for Water Balls. Adds dip port locations to all dips. [brian Troha]

 

Added CPUINFO_INT_CLOCK_MULTIPLIER to support CPU clock multipliers. Updated all CPU cores to return a CPUINFO_INT_CLOCK_MULTIPLIER of 1. Changed the core to actually respect both CPUINFO_INT_CLOCK_MULTIPLIER and CPUINFO_INT_CLOCK_DIVIDER. Updated a number of drivers to use cpunum_get_clock() instead of Machine->drv->cpu[x].clock. Raw input clock speeds should now be specified for all CPUs in the MACHINE_DRIVER. [Aaron Giles]

 

Changed TLC43076 and games using it to RGB32. Removed global Machine variable where possible. [Zsolt Vasvari]

 

Removed dirtybuffer from video/generic.c and all drivers still using it. Good riddance... Removed videoram_w, colorram_w and spriteram_w and changed all drivers using it to access RAM directly. Removed videoram_r, colorram_r, spriteram_r, spriteram16_r and spriteram16_w from video/generic.c and changed all games to use (possibly shared) RAM. [Zsolt Vasvari]

 

Cleaned up memory maps in the seibu sound interfaces. Changed to use shared sound configs instead of statically copying them in each driver. [Aaron Giles]

 

Verified and changed cpu frequencies and oki m6295 pin 7 on the following pcbs: Asuka&Asuka, Cadash, Equites h/w games and sound board, F1GP, Super Formula, Gladiator, Ping Pong king, Great Swordsman, Irem m52 sound board, Tropical Angel, Explosive Breakers, Magical Crystal, Mad Gear, Roller Aces, Chinese Hero, Simpsons, Golfing Greats, Time Pilot 84. [Corrado Tomaselli]

 

Added some more static qualifiers on recent new/changed code. [Atari Ace]

 

Fixed dbreed72 crash introduced in 0.122u5. [Mamesick]

 

Fixed HuC6280 low-speed mode so it uses 4 cycles instead of 3. [Charles MacDonald]

 

Hand fixed Road Runner's corrupted ROM. We are 99.99% sure that the bad bytes are the same as the Desert Gun ones. [Zsolt Vasvari]

 

Cleaned up leland clocks a little. Made the i186 divide-by-2 clock internal. [Aaron Giles]

 

Added clocks to the MCR sound boards and some of the MCR games. Added TMS5220 variants TMS5200 and TMC0285 as proper chips. Changed MCR squawk & talk to use the TMS5200 as documented. [Aaron Giles]

 

Cleaned up Crazy Baloon driver: proper memory maps, crystals, etc. Implemented the missing features of the collision detector custom IC. [Zsolt Vasvari]

 

First pass at fixing the cpu clock speeds on the playstation based hardware. The system 10 & 12 clock speeds have been raised as they run on an upgraded chipset. The internal divide in the CPU core has been set to 4 as we have no wait states, incorrect dma timing, no gpu timing, no dma bus stealing and no gte timing. [smf]

 

Fixed RET instruction on the i960 core. [Ernesto Corvi, ElSemi]

 

Removed speedups in the gstream and limenko drivers which were breaking the games. [David Haywood]

 

Fixed regression on i8039 T1 counter mode. [couriersud]

 

Added CUSTOM_INPUT macro for defining input port callbacks. Pushed its usage throughout the code. [Aaron Giles]

 

phoenix and clones: [couriersud]

* video timing from schematics

* palette from schematics (resnet.h)

* no more colortable

* added save state

 

Minor RSP fixes: [sGINut]

- Fixed accumulator state on powerup by testing against real hardware

- Fixed single-step behavior by testing against real hardware

 

Added save state support to atetris.c. [svante Gerhard]

 

Fixed up atetris memory maps and clocks according to schematics. [Aaron Giles]

 

Added targ and spectar to TinyMAME. [neoforma]
