Specific Contributions

The known contributions for this version are, in the order specified in the whatsnew:

  • Andrew Gardner added comments support to the debugger. You can now dynamically add comments that are visible next to the disassembly view. Comments are saved to an XML-based .cmt file in a 'comments' directory by default upon exiting.
  • Ian Patterson fixed the cheat timer to fire at the correct rate. Also fixed initialization order to work around dependency on the video/UI system.
  • Adam Bousley added save states to 3 more drivers: arkanoid.c, system1.c, and taitosj.c, and to the SN76496 sound chip for system1.
  • Lawrence Gold fixed a couple of small memory leaks and a crash bug found by valgrind.
  • Nathan Woods added save state support to the tetrisp2 driver.
  • Adam Bousley added save state support to Cloak and Dagger, Mario Bros, Crazy Baloon, and the SN76477 sound chip.
  • R. Belmont hooked up the R4650 properly in the MIPS recompiler.
  • R. Belmont made more Namco System 23 progress:
    • Further hardware work
    • Hooked up H8/3002 MCU and sound system
    • Many notes added
    • Final Furlong 2 (World and Japan sets) added
  • Nathan Woods added sanity checking to the set_visible_area() call to ensure it is not set larger than the screen bitmap.
  • smf added decryption of the BIOS for the Namco System 10 games using MEMN ROM boards.
  • El Condor changed the ROM banking of the Bellfruit 'Adder' card to the new standard, as well as tidying up the MPU4 emulation with some new information.
  • Adam Bousley added save states to Namco Classics Collection 1 & 2, Taito B System, and fixed save states in Operation Wolf.
  • Aaron Giles made the following debugger changes/updates:
    • added new streaming text buffer system
    • rewrote the console window to use the streaming text buffer
    • added new log window (Ctrl+L) which displays live error.log output
    • added disassembly view menu to control comments versus raw or encrypted opcodes
    • added disassembly menu to the main console window as well
    • now detect expressions with assignment or ++/-- operators as commands, do you can just say "pc=0" to modify registers instead of needing to type "do pc=0"
    • fixed bug that would sometimes lock the disassembly view to the top line
  • Aaron Giles and Atari Ace did more global system cleanup:
    • remapped osd_die to fatalerror, which cleans up behind itself and returns to the osd code by returning from run_game
    • removed a number of unnecessary includes from driver.h
    • moved logerror into the core
    • moved 68000-specific build rules to cpu.mak
    • new function skip_this_frame, should be called by drivers instead of osd_skip_this_frame
    • removed includes of osdepend.h and osd_cpu.h from drivers; only the core should include these
  • Aaron Giles did more initialization/reset/pause cleanup:
    • new function add_pause_callback can be called by other modules to register a callback for whenever MAME is paused/resumed
    • converted all existing pause hooks to use the new system
    • new function add_reset_callback can be called by other modules to register a callback for whenever MAME is reset
    • converted all existing reset hooks to use the new system
    • removed machine_reset; replaced with mame_schedule_soft_reset
    • new function mame_schedule_exit to force an exit cleanly from external events
    • removed all the "trying_to_quit" crap from the Windows code
    • moved save/restore system out of cpuexec.c into mame.c
    • moved core game loop out of cpuexec.c into mame.c
    • added hard reset support (complete tear down and re-init)
  • Aaron Giles shuffled some more core files:
    • split sndintrf.c into sound.c, sndintrf.c, and sndhrdw/generic.c
    • added #include vidhrdw/generic.h to mamecore.h, and removed all explicit includes elsewhere
  • Aaron Giles added save state support to the BSMT2000 sound emulator and the dcheese driver.
  • Aaron Giles fixed missing save state data in the dkong driver.
  • Aaron Giles updated the 68000 disassembler to use the new interfaces.
