Software Revision History for Flash: History

  1. Three (3) ROM chips are required for MPU boards in Flash: IC14, IC17, and IC20. 3-ROM chip sets replace some original 4-ROM chip sets (read below). We have 3-ROM chip sets in versions 0486-2 (early yellow label ROMs) and 1486-1 (later green label ROMs).
  2. Either 3-chip set will replace original 3-chip or 4-chip sets in Flash.
  3. If you have an old 4-chip, yellow-label ROM set, our IC17 and IC20 yellow-label ROMs will replace original IC17 and IC20. Our IC14 will replace original IC21 and IC22 chips (remove BOTH IC21 and IC22, install new IC14).
  4. Chip sockets IC21, IC22, and IC26 must be empty (or absent) when using either of the new 3-chip sets (only IC14, IC17, IC20 are used with the new 3-chip sets).
  5. The green label chipset version 1486-1 is a later version of the software with some changes in the audits/adjustments. Click here for a listing of ROM revisions and changed audits/adjustments.
  6. We recommend the yellow label 0486-2 version with constant background sound feature. Set adjustment #33 to '01' with this chip set, to enable background sound.
  7. Background sound is known to cut-out and come back on once in a while in some games, so no guarantees are made about operation.
  8. ROMs must be used as a matching set- ie: you cannot mix yellow-label ROMs with green-label ROMs.


Replacement sound ROM for this game is a 2716 EPROM chip and may require jumper changes on sound board, if replacing original PROM chip. See game manual/schematics for jumper settings.

The above software is provided as a service, but is not being sold. Price above reflects the cost of the service to provide the manufacturer-owned software on game-compatible media, and installation instructions for the software that comes on the media. We do not sell or own any manufacturer software.
