Changed both games to use identical video timing parameters based on measurements of darwin.
Guessed based on available information at the master clock and derived all game clocks from it.
Changed and verified frequencies on Ikari Warriors h/w, Tnk3, Hyper Sports, Jackal and S.A.R
Updated xtal.h to support the 13.4mhz crystal found on Ikari warriors and TNK3 h/w
Verified and corrected a lot of frequencies and oki6295 pin 7 on pcbs:
Double Dribble, Chequered Flag, Diet gogo, Boulderdash, Sly Spy, Psycho
Nics Oscar, Captain Silver, Magical Cat Adventure, Raiden, Superman,
Twin Hawk, Vimana, Ghox, Dogyunn, truxton2, Pipi and Bibis, Fix Eight
and Money Money
They were all verified with frequency counter, even the strangest ones
are right.
* discrete sound
* hooked up z80dma
* combined memory maps
* statics in mario_state struct
* fixed save state issues
* combine sh_* writes into one routine
The skid sound is different from the samples. Reducing the LS123 capacitor by 40% will give the same sound, so I assume this is due to capacitor aging on the board the samples were recorded.
Added code to debug 64-bit builds to allocate all address space below 4GB to help find 64-bit errors.
Added environment variable OSDDEBUGMALLOC which, if set, explicitly overrides the debug malloc debug settings.
Added environment variable OSDDEBUG4GB which, if set, explicitly overrides the new 64-bit address space allocations.
(Sadly this is necessary due to my nvidia D3D drivers being 64-bit unclean....)
Cleaned up atarijsa memory maps.
Added save state support to atarirle, and cleaned it up a bit.
Added save state support to atarig1 driver.
Fixed pitfight0109u2gre
Added talkback to narc sound boards and wired it up to the Z-unit board.
Connected Y-unit reset for various sound boards.
Added sound IRQ state detect to ADPCM board and wired it up to the Y-unit board.
Verified and documented XTALs on the Williams sound boards and Y/Z-unit PCBs.
SGI are bastards who use a 9-bit-byte framebuffer, use the extra bits to store pixel coverage, and can use the coverage bits for pixel alpha. This wont' be implemented for a good long while.
* fixes ad2083_0111u5gra - adds cocktail switch
Note: The bug report mentions "And player 2 control is not hooked up in cocktail mode."
The game will use player 1 inputs even in cocktail mode. Probably never designed for cocktail operation
* fixes skychut37b1yel
* fixes skychut37b6gre
* adds samples to ipm invaders - just rename your old invaders samples to ipminvad to test
* added - amongst others - "capsule" dip switch to ipm invaders
* sound ports identified
* demo sound and cabinet type driver configuration
* more I don't remember
- Move texture masking to occur after coordinate adjustment
- Fix 32-bit texturing in load_tile (Mario Kart 64 title screen)
- Add zero-alpha early-out (Mario 64 trees/stars, Mario Kart 64 trees/karts)
Removed hack in setting the timer in the MIPS core, which caused missed timers on the aleck64 games.
Fixed icount management in the RSP core which caused it to report negative cycle counts.
Fixes aleck64_0120red and mtetrisc0115u1red.
Added XTAL defines to bfm_sc2.c
There is also a small style cleanup for lvcards.c to remove the AGEMAME
reference which is now invalid.
I would have done the same XTAL definition for MPU4, but despite the
schematics claiming a 6.88MHz
crystal, I hven't actually had a PCB in my hands to check, and it's not
on either of the two lists in xtal.h, so I'm leaving it be.
This patch fixes the following issue in the 6522 emulation:
- When writing to the ACR register with the timer 1 in continuous
counting mode, the timer 1 value should not be reloaded but keep on
counting.
This fixes the winwork.c and poly(new).c meory leaks in the viper.c
driver. I didn't look at the x86drc.c, because Aaron said it will be
changed soon and there is no need to investigate those leaks at all.
As I wanted to update my own personal TODO about that fix I
recognised it only happens in viper.c as well, so I took a stab at
it. It was just anothe rmissing cleanup function and I also cleaned
up the *_exit() potions/usage of the cores supporting DRC a bit.
0. This patch does minor cleanup to existing layouts, trimming/padding
entries as appropriate and reformating a few layouts.
1. This patch introduces a GFXLAYOUT_RAW() macro, and uses it
throughout. It codifies the requirements for a raw layout in one
place.
2. This patch adds new validation code to the core for some previously
unchecked assumptions about layouts, and reduces the number of
references to the gfx_layout fields in preparation for a change in the
representation.
3. This patch constifies the remaining non-const gfx_layouts in MAME.
It does this by adjusting the code so that the only modification to a
layout ever needed is for the total field, which is then handled by
modifying a stack-based copy of the layout before invoking allocgfx. I
also spent some time consolidating and simplifying the layout code in
konamiic.c.
- removed years from copyright notices
- removed redundant (c) from copyright notices
- updated "the MAME Team" to be "Nicola Salmoria and the MAME Team"
* completed tms5110A code
* working speech synthesis
* documented analysis done on pcb pictures and findings
* as a consequence, marked all sound roms as BAD DUMP
* created sound driver in scramble.c
Added save state support to YM2413.
Modified slapstic code to support address range mirrors.
Cleaned up Rampart driver:
- simplified rendering code
- full memory map
- added save state
