New Version Of The Arcade Emulator Mame

Another update for what is probably the best known arcade emulator in existence but what’s been done to it? and importantly for some readers is the cheat system working again? (hey my view is if you want to turn into an invincible killing machine in game to wind down after a hard day, go for it) let’s find out shall we?

MAMETesters Bugs Fixed
• 00181: [Sound] ddragon3: OKI volume is too low in MAME. (sonikos)
• 00417: [Sound] ddragon3: the title voice should start when the background tune hits its highest note. (sonikos)
• 01441: [Sound] ctribe, ddragon3: The OKI6295 playback frequency is too high. (sonikos)
• 01888: [DIP/Input] raidena, raidenk, raident: Flip screen DIP switch doesn’t work. (couriersud)

Source Changes
MIPS3 recompiler: [Aaron Giles]
• * added UML comments for common state variables
• * removed some unused fields
• * implemented LL/LLD/SC/SCD (only works single-processor for now)

• Added sound emulation to Wily Tower, Atomic Boy and Fighting Basketball. [Tomasz Slanina]
• Improvements to squahitsa. [David Haywood]
• Progress on protection simulation for 2 Crystal System titles. Still not working. [ElSemi]
• Some progress on tankfrc4 inputs. [David Haywood]
• Created common virtual TLB managment module. Updated MIPS and PowerPC code to make use of it. [Aaron Giles]
• Added a validity check against reading input ports at init time. [Curt Coder]
• Cleaned up software bilinear filtering code. Added bounds checking. Enabled by default for snapshots and movie rendering. [Aaron Giles]
• Added new option: -snapsize, which lets you specify the target resolution for snapshots and movies. The existing behavior is still the default: create snapshots and movies at native pixel resolutions. [Aaron Giles]
• Added new option: -snapview, which lets you specify a particular view to use for rendering snapshots and movies. The existing behavior is still the default: use a special internal view and render each screen to its own snapshot in its own file. When using this option to specify a view other than ‘internal’, only a single snapshot file will be produced regardless of how many screens the game has. [Aaron Giles]
• Improved AVI and MNG recording to properly duplicate/skip frames as appropriate to keep the correct framerate. [Aaron Giles]
• Added new function video_get_view_for_target() which selects a view based on a command-line parameter and the configuration. Changed Windows OSD code to use this instead of its own logic. Changed -snapview to share the logic as well, enabling ‘auto’ as a -snapview option. [Aaron Giles]
• Renamed “Nintendo z80gb” cpu core to “Sharp LR35902″. [Wilbert Pol]

UML: [Aaron Giles]
• reactivated back-end validation mechanism
• added back-end validation for ADD/SUB/MUL/DIV/CMP forms
• fixed several errors in dealing with more obscure flag combinations

konamigx frequency tweaks: [Yasuhiro Ogawa]
• set screen refresh rate to 58Hz (parameters from developer manual are not 100% correct)
• removed sound CPU clock hack

• Set tecmosys screen refresh rate to measured 57.4458Hz. [Guru]
• Added missing machine parameters and removed deprecat.h usage in a number of drivers/ and machine/ files. [Oliver Stoenberg]
• Changed all games after Street Fighter 2 CE to have a 12mhz clock. Verified on Megaman and Quiz and dragons (original kits with plastic case). I am resonably sure all the other games after ST2CE have the DASH cps1 board with 12mhz clock. [Corrado Tomaselli]
• Converted many drivers in the d-j alphabetical range to use input_port_read() instead of input_port_read_indexed(). [Fabio Puiuli]

ddragon3 driver cleanups/fixes: [sonikos]
• Fixed the mess dips location in ctribe
• Added dips location in all sets of ddragon3
• Added the missing dips (now are 8×2) on ctribe, ctribe1, ctribeb, ctribb2 and ddrago3b
• Fixed the “Stage Clear Energy” dips in ctribe
• Adjusted the frame rate from 60hz to around 57 as reported on mametester ID 00417
• Adjusted OKI frequency to 1.000mhz (according to recording on mametester ID 00181)
• Adjusted the ddragon3 & ctribe volume (according to recording on mametester ID 00181 and 01441)

• Some protection improvements for vgoalsoc / tecmo world cup 98. [nuapete]

New games added or promoted from NOT_WORKING status
• Alien Storm 2 player World [Frederic Canoen]
