Source Changes

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

Robustified key behavior when the debugger is visible. Should now properly ignore the "break into debugger" keypress and not allow related characters to filter through. Removed some hacks related to making that work in the past. [Aaron Giles]

 

Changed osd_wait_for_debugger() to take a machine parameter and a "firsttime" parameter, which is set to 1 the first time the function s called after a break. The Windows debugger uses this to ensure that the debugger has focus when you break into it. [Aaron Giles]

 

Changed short names for STV BIOS back to single words. [brian Troha]

 

Added information on how to toggle the built-in speedup in Ms Pacman or the fast shot in Galaga in 20pacgal. [brian Troha]

 

Removed MDRV_SOUND_ADD. Renamed MDRV_SOUND_ADD_TAG to MDRV_SOUND_ADD. All sound chips must now include a tag. Changed all existing drivers to define a unique tag for each sound chip. [Aaron Giles]

 

Fixed incorrect i960 behavior when generating interrupts. [ElSemi]

 

Changed -listxml to now output the tag names for CPUs and sound chips. [Aaron Giles]

 

Added validity checks to ensure no duplicate sound or CPU tags. Fixed several duplicates. [Aaron Giles]

 

Changed MDRV_CPU_ADD to require a tag. Removed MDRV_CPU_ADD_TAG. Tagged all CPUs. [Aaron Giles]

 

TGP / Model 2 fixes [ElSemi]

- TGP now correctly uses table roms (model1/2 updated accordingly)

- removed FIFO hack on srallyc (game now runs)

- added analog ports reading for model 2A/B/C

- fixed some loading instructions in the TGP. that fixes srallyc automatic transmission bug

 

Merged CPU0 and 1 memory maps in flower, improved interrupt generation [David Haywood]

 

Dsp56156 Disassembler rewrite. [Andrew Gardner]

- Rearranged decoding behavior.

- Updated code style to MAME standards.

- Tested each single-word opcode with custom ROMs.

 

Laserdiscs are now devices. Updated all drivers accordingly. [Aaron Giles]

 

Merged memory maps in battlnts, bbusters, bigevglf, bigstrkb, and bionicc. [Aaron Giles]

 

Added new functions attotime_to_ticks() and ticks_to_attotime() to convert between attotimes and a clock tick at an integral frequency. [Aaron Giles]

 

Changed the 6532 RIOT device into a proper device. Rewrote the logic to be simpler and leverage the new attotime functions. Changed the I/O port setters to specify a mask, and changed the I/O port callbacks to pass in the previous value. Updated tourtabl and gameplan drivers to use the new device interface. [Aaron Giles]

 

Converted audio/starwars.c, audio/exidy.c, and audio/gottlieb.c to use the new RIOT implementation instead of rolling their own. [Aaron Giles]

 

Began gottlieb.c cleanup. Converted palette calculations to resistor weights. Corrected video timing. Reduced the number of separate machine drivers. Fixed incorrect spriteram sizes. Populated full memory maps for the main CPU and the rev 1 sound board. More to come. [Aaron Giles]

 

Fixed 8257 DMA terminal count stop for autoload mode and added callback function existance check. [Miodrag Milanovic]

 

Completed removal of all explicit calls to input_port_read_indexed(). [Fabio Priuli]

 

Converted tinklpit keycus implementation from a table to a LFSR. [Olivier Galibert]

 

Removed unnecessary ROM shuffling code in namconb2. [Olivier Galibert]

 

Made the initialization of various Konami PPC drivers consistent from run to run, hopefully fixing most multisession issues. Also moved some allocations from static to dynamic storage. [Atari Ace]

 

Made input_port_read_indexed() private to machine/generic.c. Eventually it will probably disappear altogether. Fixed the two remaining instances. [Aaron Giles]

 

Converted a number of drivers from A-C to using tagged input ports, and AM_PORT_READ in the address maps. [Fabio Priuli]

 

Added DIP locations to a large number of drivers: bwidow.c, bzone.c, bestleag, blackt96, bogeyman, bombjack, boogwing, bottom9, brkthru, darwin, buggychl, squaitsa, btime, bnj, lnc, zoar, disco, cabal, canyon, cbuster, cclimber, swimmer and guzzler. [Fabio Priuli]

 

Made DIP switch renderings consistent regardless of UI aspect. [Aaron Giles]

 

Moved more items out of .data by either applying const, removing the non-zero initializer (if its overwritten by init/reset) or by adding appropriate initialization code. [Atari Ace]

 

Removed conditional logging code in favor of allowing the compiler to optimize it out. This prevents bitrot of #ifdef'ed code. [Atari Ace]

Shinobi III (Mega Play) [Tomasz Slanina, Kowal]

Rail Chase 2 [AndyGeezer]

SNES emulator

This release adds SPC7110 emulation, without the need for graphics packs!!, and a rewritten S-RTC (real-time clock) emulator.

 

SPC7110 support means that Far East of Eden Zero, FEoEZ: Shounen Jump Edition, Momotarou Dentetsu Happy and Super Power League 4 are now all fully playable. I will warn you, the emulation is very slow in this version -- while most areas of each game will run at the same speed as other games, there are a few peak moments where speed will drop by up to ~50%. The reason for the slow-down is that I am currently uncertain how to determine the amount of data to decompress in advance, so I default to the maximum amount possible. The reason I am releasing now anyway, is because I beleive in the "release early, release often" paradigm. It will likely take me a few weeks to finish researching this chip, and I didn't want to keep the work I had private during that time. But rest assured, bsnes v034 should feature much faster SPC7110 emulation.

 

neviksti, Andreas Naive and jolly_codger worked non-stop on the SPC7110 decompression algorithm for the past two weeks. caitsith2 provided valuable data to the effort. I only wish that I could've been of some use, but alas, I had no role in this. In the end, it was neviksti who managed to crack all three(!!) compression modes of this chip, which turned out to be a customized 8-bit QM-coder with a prediction model. You can read more about this here. I would also like to thank Dark Force and John Weidman (aka The Dumper) for their research notes on the SPC7110 register interface.

 

For those who don't understand the hoopla about figuring out this compression algorithm when we already had graphics pack simulation, I should note that we have since found a few errors in these packs. Not to mention, you no longer need ~4-16MB packs for each game you wish to run. They work like any other game now. Better still, the chip can now be used to compress new graphics, eg for any future translation efforts on these titles.

 

The real-time clocks in both Far East of Eden Zero and Dai Kaijuu Monogatari 2 will now save a ".rtc" file in your save folder, which contains the clock as set by the video game, as well as a timestamp from your computer when the time was last updated. It uses the difference between the saved timestamp and current time to update the time. This allows you to specify any time you like, whereas previously bsnes would just use your computer's current time, ignoring the time you set in-game. It also allows the "round clock by 30 seconds" option in both games to work. I avoided this before because this method makes supporting daylight savings time and such impractical, although I should note that the original hardware did not support DST, either. This method was required to pass the SPC7110 tests, and is overall much more faithful to how the original chips worked.

 

Once again, I'd really like to personally thank neviksti for his tireless efforts. Eliminating graphics packs from SNES emulation was one of my primary reasons for getting involved in the SNES emulation scene. That neviksti managed to crack this algorithm means a lot to me. Thank you so much, neviksti. This release is dedicated to you, now go get some sleep
