Source Changes
————–
Updated LFO information in YMF271 core. [Brian Troha, Nicola Salmoria]

Fixed parent relationship between sbrkout3 and sbrkout.
[Lord Nightmare]

Removed some magic numbers from machine/psx.c, replaced with #defines.
[Harmony]

Change to consistently use Intel notation for hex values in TMS32010
disassembler, rather than a mix of Motorola and Intel notation.
[Lord Nightmare]

Z80: Check for NOP in interrupt mode 0. This allows code like ei /
halt / di to work correctly. A better solution would be to implement
full support for arbitrary opcodes in mode 0. [Dirk Best]

igs017.c update [Luca Elia]
– Merged in some IGS031 based games (igs_m68.c, tarzan.c)

(Top Racer) sets. Removed Namco devices from bootlegs which don’t
have them. [David Haywood]

Added save state support to plygonet.c and the DSP56156 CPU core.
[Andrew Gardner]

Updated SN76489/A to have correct PRNG waveforms (a 0 bit was missing
at the beginning, and beginning of SN76489 waveform was all 1s
instead of 0s as measured on hardware). Added SN94624 (same as
SN76489). [Lord Nightmare, plgDavid (David Viens)]

IGS blitter based games update [Luca Elia]
– Renamed driver to igs011.c and cleaned it up

– Implemented hopper in lhb, lhb2, wlcc
– Decrypted ryukobou

i386 core fixes: [Barry Rodewald]
* Added Nested Task flag, and I/O Privilege flags. They aren’t
implemented in any way, but can now be set or reset. Can be used
to detect a 80386 or later CPU.
* Implemented ENTER instruction.
* Made IRQ vectors treated as 8 bytes when in protected mode, and
made the addresses pushed onto the stack 32-bit if the gate
descriptor used is a 386 interrupt or trap gate (also when in
protected mode, will always be 16-bit if in real mode).

Fixes to default mapping as well as comment/information fixes for
Mole Attack [M.A.S.H./Tafoid]

Identify puyoj set as Rev B and correct various rom names.
[Smitdogg, Dumping Union]

Improved Super Nova sprite shrinking, used by Gals Panic S2 and

Allowed child CPUs to be used in read8/write8 callbacks. [Curt Coder]

Jaleco Mega System 32 update: [David Haywood]

* Implemented priority in the same manner as tetrisp2
* Add shadows via custom mixing (gametngk and tetrisp / tp2m32 are
much improved)
* Added the alt tilemap layout used by f1superb for the backgrounds
* Added f1superb notes and IRQ generation code from nuapete

Tournament Solitaire (pcat_dyn) improvements [luigi30]:
* Added newer version of toursol, renamed existing to toursol1 and
the new one is now toursol
* Set toursol date to 1995
* Set toursol CPU speed to 40MHz

Many improvements to konamigx rendering, specifically improving
Soccer Superstars and Rushing Hero. [David Haywood, Angelo Salese]

Implemented input buffer copy protection in Rushing Heroes, game is
now somewhat playable with heavy gfx glitches [Angelo Salese]

Fixed Konami GX type 4 protection seed $d15, used to protect a sprite
bank in Run & Gun 2 / Slam Dunk 2 [Angelo Salese]

Fixed sprite ROM loading in Slam Dunk 2 [David Haywood]

Added missing BLTZAL opcode to the RSP core. [angrylion]

Control fix for Strike Gunner S.T.G. to allow a 3rd button mapping
for each player – thus allowing for the feature of merging ships in 2
player games. [Tafoid]

Marked cosmic alien colors as wrong, added TODO to the driver for
fixing colors. Added new XTAL value for cosmic alien and switched
driver to use it. [Lord Nightmare]

– Fixed disassembly for EC/LC variants of ‘030/’040

Patched NVRAM check in Jackpot Cards, makes the game playable but you
cannot save settings so it’s not yet working. [Angelo Salese]

Trashed the old pre-accurate-clocking STEP based sample averaging
scheme from sn76489 and friends, vastly simplifying the code. Made
the output bipolar rather than only above the 0 line. Added missing
statement to the get_safe_token function for the recently added
SN94624. [Lord Nightmare]

Many N64 RDP fixes.
[angrylion, Ziggy, Gonetz, Orkin, DrgnMndd, Harmony]

Cleaned up toaplan2 V25 support, enabled Batsugun V25 and added
decryption table info for the other games [David Haywood]

Improved the V25S memory map in Batsugun, now CPUs starts to
communicate properly, needs to find & implement the irq that clears
the RAM flag and decrypt the relative opcodes in that. [Angelo Salese]

More Greyhound improvements: [Mariusz Wojcieszek]

[Lord Nightmare, Justin Kerk]
