0.37b12 [Phil Stroffolino]

< Japan >

Bugs:
  • The rotating logo is garbled. Terryn (ID 02357)
WIP:
  • 0.127u4: Added M37702 MCU rom (c70.bin - 16k). Replaced Namco NA sound with M37702 (12528250 Hz) CPU2 and C140 (44100 Hz) sound. Replaced M37710 CPU2 with M37702 in clones (Japan) and (Japan Version B).
  • 0.125u4: Changed C140 clock speed to 44100 Hz in clones Emeraldia (Japan) and (Japan Version B).
  • 0.125u2: Phil Stroffolino fixed long-standing bug with Emeralda text colors. A sprite attribute exists which signals an alternate interpretation of palette ram. Added a mask when processing the ROZ tilemap to avoid defects in Emeraldia (Japan Version B).
  • 16th May 2008: Phil Stroffolino - I've unraveled some of the last few mysteries of Namco's NA1 system hardware. The "rotate and zoom" layer so far appears to only be used by a single game, Emeralda. The single oddest feature I encountered was a spriteram attribute that causes the palette to be interpretted in a radically different manner. This fixes the onscreen score text in Emeralda, which, now that it is correctly emulated, features color gradients and anti-aliasing. This same effect could have been accomplished more-or-less equivalently with the standard -rrrrrgggggbbbbb palette. I'm baffled as to why hardware designers and software would have implemented the feature in such a roundabout manner. A screenshot featuring the corrected colors is featured below.
  • 0.125u1: Phil Stroffolino fixed the ROZ effect in Namco NA1 driver. This adds a missing NAMCO logo zoom/spin effect in Emeralda's attract mode. Also added support for scanline effect (this fixes invisible dolphin in Emeralda attract mode).
  • 0.124u2: Pierpaolo Prazzoli enabled ROZ tilemap in Emeraldia, but it's not centered in the right position when it's not in its original dimension.
  • 0.124u1: Pierpaolo Prazzoli removed Emeraldia hack and changed background pen to fix Emeraldia demo.
  • 20th September 2006: Dumping Project - Purchased Emeraldia (World set). Thank go to the fivepeople who recently donated after the last request. A special thanks goes to Kevin.
  • 0.106u11: Brian Troha added Emeraldia (World). Renamed (emeralda) to (emeraldj) and (emerldaa) to (emerldja).
  • 0.60: Added clone Emeraldia (Japan).
  • 25th June 2001: David Haywood added another Emeraldia romset to the Namco NA-1 driver.
  • 0.37b12: Phil Stroffolino added Emeraldia (Namco 1993).
  • 19th January 2001: Phil Stroffolino re-submitted the Namco NA1/2 drivers, with Emeralda, Tinkle Pit and Cosmo Gang the Puzzle as completely playable games. The rest run through the attract mode but suffer from unmapped input ports.
  • 16th September 2000: Phil Stroffolino sent in an improved Namco NA-1/2 driver, adding support for Exbania, Nettou! Gekitou! Quiztou!!, Super World Court, F/A (Cosmo Gang the Puzzle, Tinkle Pit and Emeraldia were added back in June).
  • 7th September 2000: Phil Stroffolino sent in the Namco NA-1 driver, still supporting Cosmo Gang the Puzzle, Tinkle Pit and Emeraldia.
  • 12th August 2000: Phil Stroffolino sent in the Namco NA-1 system driver, semi-working games are Cosmo Gang the Puzzle, Emeraldia and Tinkle Pit.
  • 26th June 2000: Phil Stroffolino sent in a preliminary Namco NA-1 driver, which supports Cosmo Gang the Puzzle, Tinkle Pit and Emeraldia as nearly playable games.
