MAMETesters Bugs Fixed


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

  • Vas Crabb updated chdman.cpp: fix for code that expects to be able to dereference a pointer that it knows may be null.
  • Brizzo and MetalliC redumped Atomiswave BIOS, confirmed good, added information.
  • O. Galibert updated screen.cpp: Add svg shapes pre-computation.
  • Carl updated plugins/layout: layout embedded script helper plugin.
  • O. Galibert updated the h8 core: Add dtc, dma, watchdog (WIP).
  • O. Galibert updated the cybiko driver: Make work a little more, add v1 flash.
  • Fabio Priuli updated the a5200 driver: fixed regression when loading headerless carts from fullpath.
  • Fabio Priuli updated neogeo.cpp: huge clean up of the cartslot code in order to better exploit slot devices:
    • moved cart-specific components to the carts itself removing the fake protection devices from the main system, since they never belonged there.
    • removed hacky rom region destruction/construction when a new cart is inserted, replacing it with proper bank pointers to the carts (except for ymsnd and ymsnd.deltat region which will require modernization of the ym devices).
    • started re-organization of bootleg boards emulation, so to reduce the need of collapsing everything into a single cart type with multiple protection devices, more work is needed.
  • Fabio Priuli updated neopcb.cpp: moved to a separate source file the emulation for JAMMA PCB versions of a few neogeo games, since they don't have a cartslot.
  • Fabio Priuli updated neogeo.xml: added information about Japanese titles and release dates to the software list and aligned the list to the driver.
  • O.Galibert updated the cybiko driver: Remove the ram mirror, it hides when the code fails.
  • O. Galibert updated vector.cpp: Move clipping to avgdvg, the only user. Simplify.
  • Fabio Priuli updated nes.cpp: removed configuration settings to enforce sprite limit and to turn off drawing of top/bottom 8 lines: the code to make these work was removed before 0.106 and the option were doing nothing since then.
  • Corrado Tomaselli dumped program rom for Gigas (MC-8123, 317-5002) Gigas set, works now.
  • AJR made watchdog timer a separate device.
  • K1W1 provided a few additions to A800 software lists.
  • Fabio Priuli updated the megadrive driver: added custom X24C02 emulation to NBA Jam cart, making finally possible to save records at exit. Hopefully, this will help finding the problem in our core emulation.
  • Roberto Fresca updated the Sonik Fighter (encrypted) driver: Decrypted the program, changed the game description adding version, and corrected year.
  • Fabio Priuli updated the megatech driver to use fixed slot config.
  • system11 updated skns.cpp: add the Korean modbios.
  • winteriscoming dumped Wangan Midnight Maximum Tune 1/2 card reader-printer firmware.
  • Smitdogg dumped Initial D card reader-printer firmware.
  • Fabio Priuli updated sv8000.cpp: inputs are more appropriate as IPT_KEYPAD.
  • Ryan Holtz updated model1.cpp: Some modernization and cleanup.

    • Fixed decrypted opcodes hookup.
    • Preliminary T5182 hookup.
    • Added base sprites.
    • Fixed sound comms (reversed semaphore access wrt darkmist), coins and sound now fully working.

    • Added proper machine driver and memory map.
    • Added D-Up, Take, Bet, Start, Main Door switch, Logic Door switch, Cash Door switch, Coin A, Coin B, Coin C, Reset, Stats/Setup, and GFX selectable DIP switches.

  • Couriersud continued work to move object initialization from start to constructor. Removed family_t. All of this can be determined at runtime from object as well. As part of this, the "template" to write devices has changed. Converted a number of devices to use the new template.
  • Couriersud made all netlist devices now follow new syntax. Removed dead code. All sub devices are now forced to be initialized in the constructor. Device setup now completely in constructor. Removed start call.
  • R. Belmont updated apple2c.cpp:
    • Writing to VBLDIS also lowers the VBL IRQ if it's active.
