Specific Contributions

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

  • Nathan Woods updated the MC146818 module to use new core date/time routines.
  • Nathan Woods cleaned up disassemblers to remove stubs and ensure the disassemblers are not referenced except in debug builds.
  • David Haywood added support for using CHDs to decrypt CPS2 games. This code is disabled for the moment, but will be enabled in the future. Only a handful of games have complete tables so far. These tables are huge (~4GB) and uncompressable until the encryption algorithm is understood.
  • smf fixed a bug in the debugger that caused watchpoints to not be active until the next context switch.
  • smf cleaned up the input definitions for n-way joysticks so they are more explicit. Added concept of a "16-way" joystick, which is a joystick that doesn't prevent simultaneous opposing directions from bring reported.
  • smf commited a major System 573 update:
    • fixed PSX SIO control register behavior
    • added uPD4701 emulation
    • fixed ATAPI reset, PIO, and command IDENTIFY PACKET DEVICE
    • hooked up controls for fishing, DRR, and Guitar Freaks games
    • hooked up CDDA audio
    • removed some unused bytes from the Konami 80's security chips
  • Canim fixed the upside down service mode in the commando.c driver.
  • Atari Ace reorganized the Galaxian/Scramble driver:
    • machine/scramble.c is broken up into two files, machine/galaxian.c and machine/scramble.c
    • drivers/amidar.c, drivers/frogger.c, drivers/scobra.c get copies of some of the data structures they shared from other drivers
    • galaxian_base is made static and uses outside of the main driver were rewritten
    • cclimber_decode code from drivers/cclimber.c was separated into its own machine/cclimber.c file to allow mshuttle to share it without taking on other dependencies
  • Pierpaolo Prazzoli made some improvements to trivia madness driver. There still is something wrong in the question roms banking.
  • Mariusz Wojcieszek commited more updates to the ST-V driver:
    • vdp1: added shading for sprites (used by znpwfv, cotton, others)
    • vdp1: fixed sprite clipping (fixes incorrect sprites in znpwfv)
    • vdp1: fixed transparency on colour lookup table sprites (fixes bad sprites in znpwfv)
    • vdp2: fixed caching of RGB layer (fixes bad backgrounds on bosses in rsgun)
    • vdp2: added additive blending for tilemaps and sprites (rsgun)
    • vdp2: added vertical line scroll and linezoom (fixes diehard logo)
    • stv: improved speedups for diehard
    • stv: fixed speedups for znpwfv
    • stv: added preliminary save state support
  • Aaron Giles did a significant cleanup of chd.c:
    • got rid of the horrible last_error concept; now all routines return an error directly
    • fixed several issues in managing metadata
    • changed compression and verification routines to be client-driven rather than monolithic
    • changed internal codec usage to be more flexible
    • altered chdman and MAME to use the new interfaces
    • added new -createraw command for creating raw data CHDs
  • Aaron Giles fixed a crash bug in romcmp when comparing ZIP files.
