Version 0.103u2

Released: 2005-01-11

MAMETesters Bugs Fixed

  • midres056gre [Bryan McPhail]
  • ddragon077u3red [Bryan McPhail]
  • airbustr37b9gre [Pierpaolo Prazzoli]
  • turbofrc0103gre [Pierpaolo Prazzoli]
  • turbofrc37b1gre [Pierpaolo Prazzoli]

Source Changes

  • Fixed sound bug in Phoenix sound effect #2 [Hans Andersson]
  • Fatal Fury 2 - Emulated Protection
  • King of Fighters 10th Anniversary - Added code to update SRAM tiles on the fly
  • CCTHD2k3 - Fixed GFX / Colours
  • Added code to support remaining NeoGeo sets
  • Fixed Mat Mania dipswitches [Roberto Fresca]
  • Fixed some Leap Year calculates [William Krick, smf]
  • Sync Refresh / Waitvsync / Triplebuffer changes [Alan Kamrowski II]
  • It changes the waitvsync code to wait for the beginning of the vertical blank. The previous code simply checked if it was in the vblank and only waited if it wasn't. This caused 2 problems. The first is that when using syncrefresh, if there was enough time, more than one frame can be rendered during a single vblank. This is why syncrefresh would have odd behavior such as the game speeding up or slowing during during less cpu intensive sequences. The second problem is that the retrace line could sometimes be seen because while the code checked to see if it was in the vblank, it did not check where in the vblank it was so it might be at the end of the vblank and by time the frame is rendered the monitor could be out of the vblank.
  • It removes the waitvsync only if game speed is above 95% restriction. This restriction would only cause waitvsync to vacillate between on and off depending on game speed. If someone enables waitvsync and it is too slow, then it is.
  • When syncrefresh and triplebuffer are used, MAME would run the waitvsync code anyway. The triplebuffer code takes care of this and having MAME wait for the retrace in the waitvsync code anyway is a waste of time and causes timing issues on some hardware. If triplebuffering is enabled, then there is no need to run the waitvsync code because triplebuffer already does.

Version 0.103u5

Released: 2005-02-02

MAMETesters Bugs Fixed

  • esb065gre [Mathis Rosenhauer]

Source Changes

  • Undid fix for turbofrc37b1gre since it broke more things that it fixed. [Pierpaolo Prazzoli]
  • Fixed minor color issue in Cookie & Bibi. [David Haywood]
  • Updates to the Hyperstone core: [Pierpaolo Prazzoli]
  • Removed nested delays
  • Added better delay branch support
  • Fixed PC seen by a delay instruction, because a delay instruction should use the delayed PC (thus allowing the execution of software opcodes too)
  • Hooked up watchdog for NeoGeo games and removed a number of hacks. [David Haywood]
  • Fixed hanging at the end of level 3 in klondkp. [Pierpaolo Prazzoli]
  • Fixed inputs in Renju Kizoku, Neratte Chu, Mayjinsen 2 and some dips in Neratte Chu, Mayjinsen 2. [Sonikos]
  • Improved auto_malloc so it uses less memory and doesn't have a hard-coded limit on the maximum number of allocations. Also audited the use of auto_malloc in the code and removed unnecessary checks for NULL (since auto_malloc doesn't return if it fails). [Atari Ace]
  • Fixed osd_fopen error reporting to return the correct value if you hit MAX_OPEN_FILES. [Nathan Woods]
  • Changed several byte operands in the i386 disassembler to be diassembled as unsigned rather than signed. [Nathan Woods]
  • Discrete sound updates: [Derrick Renaud]
  • Added new DISCRETE_CSVLOG module that lets you log discrete nodes as CSV (comma separated values) data.
  • Modified discrete core to use the clock specified in the MDRV_SOUND_ADD line. If the clock is specified as 0, then the discrete emulation will default to the audio sample rate clock.
  • Tweaked Phoenix Effect 2 sound to be more accurate matching oscilliscope data. Changed the Phoenix discrete clock rate to a fixed rate of 120000 allowing the simulation to be more accurate with less alaising noise at the cost of speed.
  • Fixed the bug in the DISCRETE_NOTE module that produced notes 1 count off.
  • Added support for registers that are not to be displayed in the register list. This is useful for registers like AX on i386, so that AX can be used in expressions but not represented on the register list. Simply precede the register name with '~' to prevent display. [Nathan Woods, Aaron Giles]
  • Added support for the various x86 8-bit and 16-bit derived registers, as hidden registers in the i386 core. [Nathan Woods]
  • Fixed background music in ESB. Updated IRQ frequency and divider to match the schematics. [Mathis Rosenhauer]
  • Improved dip switches for rocktrv2. [Chaneman]
  • Separated the allocation of graphics data from the decoding. This fixes the crashes that were introduced in u4, and will allow for decoding progress to be reported eventually. [Aaron Giles]
  • Made a clean-up pass over all the makefiles. rules.mak is gone now, replaced by cpu.mak and sound.mak. mame.mak has been reorganized. All the makefiles are now commented and should be easier to follow. [Aaron Giles]
  • Rewrote artwork scaling function to compute accurate sum over all contributing pixels. This produces better results when scaling high resolution artwork down to lower resolutions. Kept existing bilinear filter for scaling low resolution art to higher resolutions. [Aaron Giles]
