additional information
info 0.67 [David Haywood, Tomasz Slanina]

0.60 [David Haywood]

Bugs:
  • tbowl, tbowlj: Sometimes the player sprites get cut in half, the field glitches, and other oddities happen. Smitdogg (ID 00967)
WIP:
  • 0.126u5: Andrew Gardner merged memory maps for Tecmo Bowl.
  • 0.106u9: David Haywood updated the Tecmo Bowl driver to support dualscreen (2x 256x224).
  • 0.98u3: Pierpaolo Prazzoli added coin counter and fixed sound in Tecmo Bowl. Adding 2x MSM5205 (384000 Hz) sound and swapped sound1 roms.
  • 0.67: David Haywood added Tecmo Bowl (World?) (Tecmo 1987) and clone (Japan).
  • 0.60: David Haywood added (Testdrivers) Tecmo Bowl (World?) and clone (Japan). Issues: Sprites not done. Sound incomplete (what plays the sample roms). Game Doesn't Behave Correctly. Most inputs seem to be ignored once you start a game? The game only does one move / throw then just seems to sit there counting the clock down. When the clock reaches 0 the game doesn't end. Not sure why this is happening, incorrect shared ram? Incorrect banking? (its from wc90.c / tecmo.c and seems quite common to tecmo even if some bits are unused) Communication failure? Protection? Missing something blindingly obvious? NMI routine of main CPU? NMI routine of 6206B (1st CPU) is never called at the moment!
  • 2nd April 2003: David Haywood added sprites and fixed the interrupts in Tecmo Bowl so it's working now, though the sound emulation is incomplete.
  • 1st April 2003: David Haywood doubled the palette RAM size in Tecmo Bowl but there are no other improvements.
  • 30th April 2002: David Haywood resubmitted the Tecmo Bowl driver with proper controls, but it is still unplayable.
  • 22nd January 2002: David Haywood sent in a preliminary Tecmo Bowl driver, which is unplayable, missing sprites and sound is not completely emulated.
