  • Fixed crash in i8x41 cpu core reading uninitialized internal RAM [Juergen Buchmueller]
  • Super Qix driver update [Nicola Salmoria]
  • manually repaired the ROM code and added support for the I8751 MCU, so the two original sets work.

Version 0.90u1

Released: 2005-01-08

Thanks to Pierpaolo Prazzoli (Reip) for putting together the 0.90 release while I was away

General Improvements

  • FD1089 decryption [Nicola Salmoria, Charles MacDonald]
  • 100% accurate emulation of FD1089A, FD1089B should be considered 99% because it will have to be verified with other CPUs (it is 100% for all currently supported games).
  • complete tables provided by Charles MacDonald for 317-0018 (Action Fighter), 317-0022 (Dunk Shot), 317-0168 (Aurail).

  • improved documentation on the various register layouts on the video side
Note that in the process, I broke the title screen animation for Laser Ghost, and there is now a 1-pixel column error on ddcrew's attract mode. These are known issues that I will try to address soon.
  • Some ST-V fixes which allow seabass to run [Angelo Salese]
  • Taken out the resource file from the windows objs when UI=1 (for MAME32) [Chris Kirmse]

src/drivers/arcadia.c:
src/includes/amiga.h:
src/machine/amiga.c:
  • Refactors code specific to the Arcadia arcade system and the Amiga computer out of src/machine/amiga.c into callbacks. This allowed me to get rid of all #ifdef MESS code out of src/machine/amiga.c
  • ST-V updates [Angelo Salese]
  • Fixed a bug with the VDP-1 ram reading, SH-2 can do byte or word access, it's implicit that can't do long word access. This fixes the Steep Slope Sliders booting so the game now works.
  • VDP-1 PTM's "draw by request" was actually causing sprites to flicker in kiwames,reversed back to old implementation until I or somebody else understand what the current issue is (clear_framebuffer?)
  • Finished the game header update,let me know if you like/don't like the system used for the description of the games.
  • fixed a ST-V visible area incorrectness which was causing Virtual Mahjong 2 to crash after the sound ram check
  • fixed a window effect bug in Double-density interlace mode,this fixes some graphics in vmahjong & myfairld.
  • Guessed a bitmap positioning issue in double-density interlace mode,this fixes the NBG1 positioning in myfairld.
  • My Fair Lady now works but only with sound disabled.I have not removed the NOT_WORKING status due to that.
  • New Sound Functionality [Derrick Renaud]
  • Took Frank Palazzolo's DISCRETE_FILTER2 code and made it work outside of the discrete system. See sound\filter.h for new functions.
  • Added op-amp bandpass filtering circuit to sound\namco54.c
  • Game Driver Changes
  • bosco, galaga, polepos, xevious - added proper filters to new Namco54 noise source.

src/cpu/g65816/g65816.h:
src/cpu/g65816/g65816ds.c:
src/cpu/g65816/g65816ds.h:
src/cpu/g65816/g65816op.h:
  • Cleaned up the code a bit; make some functions static and added step over/out support to the disassembler.

  • Added more data to Super Hang On Table
  • Increased the amount of adjustable memory banks from 24 to 32. [Nathan Woods]
  • ST-V Update [Angelo Salese]
  • Started to work with the A-Bus protection,it is a sort of data transfer with the cartridge area,more info in the stv.c file.
Current implementation just fixes character selection screens in sss,I will work out about this one in the future,it has various "interesting" issues which was thought to be emulation probs(i.e booting in rsgun,textures in elandore etc.).
  • Added a preliminary timer 1 irq handling,it fixes pblbeach booting but it doesn't work yet because of incomplete VDP-1 emulation.
  • Noticed that ignoring VDP-1 long word access read by SH-2 isn't correct and not needed (because sss is protected rather than using an illegal procedure),it was causing wrong graphics in fhboxers & boot errors in pblbeach,reversed it back to default.
  • Added missing Player 2 controls to Space War (Leijac) [Steve Ellenoff]
  • Pacman Driver Update [Dave Widel]
Sets added:
  • jumpshtp: prototype from PokeMAME
  • vanvanb: bootleg but it looks earlier.
  • sprglobp: Not sure if this is the official set, or an accidental merged set with the glob.
  • ctrpllrp: I consider this sig. since it came in it's own cab, and they did change some of the music.
Other changes:

  • Added a jumpshot dip.
  • I didn't remove any sets, but I mentioned which of them are junk imo and why.

  • Arcadia Update [Mariusz Wojcieszek]
  • changed driver to use multi bios setup
  • added support for TenPlay bios (from 10 games board)

  • Tilemap Update [Aaron Giles]
Added a user_data field for tilemaps. You can call tilemap_set_user_data() to set this field internally in the tilemaps. Before rendering, this value will be copied into the (new) global tile_info.user_data field, so that your tilemap callback can use it
  • Kaneko update in preparation for data from Blood Warriors [Sebastien Volpe]
  • Preliminary decryption of Shisensho II [Pierpaolo Prazzoli]
note: still being worked on
