SERVICE MODE:
  • To enter service mode hold P1 Start during ROM test.
NOTE:
  • When you set the "Bonus Lives" dipswitch to '60k 120k', the game says '80000 160000' instead of '60000 120000' in the service mode. Dipswitches are correct. Note however, that when you set the "Bonus lives" dipswitch to '60k 120k', it is written '80000 160000' in the test mode (this is an ingame bug, not a MAME bug !). In bermudaj, the bug in the test mode for "bonus life" was fixed : it is written "60000 120000". stephh
WIP:
  • 0.127u7: Stephane Humbert checked inputs and dipswitches via Z80 code analysis for Bermuda Triangle and clone (Japan).
  • 0.127u1: Changed description of 'Bermuda Triangle (Japan)' to 'Bermuda Triangle (World?)' and clone 'Bermuda Triangle (Japan old version)' to 'Bermuda Triangle (Japan)'. Renamed (bermudao) to (bermudaj). SNK rewrite [Nicola Salmoria]: Fixed sprite-sprite priorities. Removed ROM patches, simulated "turbo front" check, clarified the relationship between the sets, converted to tilemaps, proper memory maps and inputs etc. Changed Z80 CPU2 clock speed to 4MHz and visible area to 224x368.
  • 0.126u5: Fixed gfx3 rom addresses to $8000/10000/18000.
  • 0.68: Renamed (bermudat) to (bermudao) and (bermudao) to (bermudat). Changed visible area to 224x384.
  • 0.62: Renamed (bermudat) to (bermudao) and (bermudaj) to (bermudat).
  • 0.37b6: Changed Z80 CPU2 clock speed to 5MHz.
  • 0.36b16: Replaced YM3526 sound with Y8950.
  • 28th January 2000: Bryan McPhail added a Bermuda Triangle clone to the SNK driver.
  • 0.36b14: Replaced YM-3812 sound with YM-3526.
  • 0.36b3: Alessio Manuele added clone Bermuda Triangle (Japan).
  • 0.35b8: Carlos A. Lozano and Phil Stroffolino added Bermuda Triangle (SNK 1987).
