Flashback 2 PC Board Revisions


Revision  Revision Description
Rev. 0X
  • Rev. 0X has a problem with the synthesized voice in Quadrun not working due to a problem with the emulation of the original console’s audio output. (When play begins, the game should speak “Quadrun” three times.) It also contains a prototype version of Millipede programmed by General Computer Corporation;[5] this version has problems with the display losing vertical hold and appearing to “roll”, making the game unplayable. This revision had the early delivery data to the chip fabricator and was not meant to be run into production. While this is commonly called Rev. A it is properly termed Rev. 0X
Rev. A/B
  • Rev. A Is the correct production revision of the chip which fixes the voice synthesis in Quadrun and also contains the Atari Inc. version of Millipede as well as a newer revision of Adventure 2 that is easier to see on certain TVs that experienced too dark a color palette. This revision is sometimes referred to as Rev. B since it was the 2nd series of release.
Rev. C
  • Rev. C features a reduced-size PCB, which was designed to simplify installing a cartridge port (as described below). There are no changes to the unit’s functionality; the Revision C chip corrected some Hmove incompatibility issues, but still lacked several 65xx Illegal OpCodes and support for FE bankswitching.
Rev. X
  • Rev. X features a counterfeit PC board. This model was sold at Krogers Grocery store beginning in 2010. This board has inferior workmanship. The forged PC board lacks stenciling on the solder pads to identify where to connect a cartridge modification.
