Game ROM Information- Attack From Mars L1.13
Note: We stock this, and other custom and unique ROM chips listed on our ROM Chips page.

NOTE:

Version 1.13: This beta ROM is a version of software released from Williams for testing purposes. It is "free play only". It will not take money to do pay-for-play.
Version 1.13B: This is the same as 1.13, but allows for "coin play" (not free-play only).

Changes since version 1.1:

Addition: Some lamp effects have been added.
Bug fix: "Light Extra Ball" random award was being counted in the "Random EB Lit" audit twice. This has been fixed.
Bug fix: Coin door open display message no longer interferes with bonus.
Bug fix: When the timed super jackpot in the main multiball mode was running when Rule The Universe mode was started, the super jackpot was being forgotten, which resulted in no super jackpot being lit during the Rule the Universe mode. This has now been fixed.
Change: A larger 8mb ROM chip is now required for this software version.
Change: The video mode extra ball is now no longer being percentaged. If extra ball(s) are available, it should now always come out on, or about, the 30th saucer during the mode.
Change: Ball search has been sped up.
Change: Firing strength of the jet bumpers has been decreased, which will help preserve the condition and lifespan of the red pop bumper skirts (often damaged on this game).
