Notes:
  • iqblocka: Keep start or test pressed during boot to enter test mode A or B.
WIP:
  • 0.124u4: Changed description of clones 'IQ-Block (V127M)/(V113FR)' to 'Shu Zi Le Yuan (V127M)/(V113FR)'. Luca Elia bypassed the protection in clone Shu Zi Le Yuan (V127M), emulated the video hardware and inputs & sound. Changed Z180 CPU1 clock speed to 8MHz. Changed visible area to 512x240. Added missing dipswitches.
  • 27th February 2008: Luca Elia - Further steps in the emulation of the IGS games using a Z180 CPU and the IGS017 ASIC. The latter is the video chip (tilemaps + free form sprites) and protection device. This work is based on the decryption, Z180 fixes and skeleton driver done by Pierpaolo in September. I succeded in bypassing the protection(s), so as to emulate the video hardware, add inputs and sound (see screenshots from IQ-Block (V127M)). This is the new version of the already emulated IQ-Block (although I can't read the actual title), released three years later with better graphics and on different hardware.
  • 0.119u3: Pierpaolo Prazzoli fixed clones IQ-Block (V127M) and (V113FR) - Game now playable. Changed description from clone 'IQ-Block (set 2)' to 'IQ-Block (V127M)' and 'IQ-Block (set 3, French?)' to 'IQ-Block (V113FR)'. Changed region gfx1 to gfx2.
  • 0.118u3: Added clone IQ-Block (set 3, French?).
  • 0.113u3: Added clone IQ-Block (set 2).
  • 0.66: Added YM2413 (3579545 Hz) sound.
  • 7th March 2003: David Haywood added sound to IQ Block.
  • 0.60: Nicola Salmoria added IQ-Block (IGS 1993).
  • 18th April 2002: Stephane Humbert updated the News and IQ Block drivers with correct inputs and dipswitch settings.
  • 17th April 2002: Ernesto Corvi figured out the protection in IQ Block and Nicola Salmoria finished the driver, except sound is not yet emulated in it.
  • 16th April 2002: Nicola Salmoria sent in a preliminary driver for IQ Block which shows the service mode but doesn't work otherwise.
