Summary | 07151: astdelux and clones: [possible] On launch a series of FFFFFF display multiple times in high-score position 1. | ||||
Description |
When starting astdelux for the first time or doing a hard reset w/ F3 there are a series of Fs that appear drawn multiple times in the high score #1 position. I don't recall this happening in older builds. MAME v0.203 (mame0203-287-g748f6ed903) Could be more accurate emulation behavior with a recent change I suppose, but not sure. |
||||
Steps To Reproduce |
Launch astdelux Observe FFFFFs drawing in the high score areas before reverting to regular attract mode. |

My friend worked on an astdelux board a few months ago, says he thinks he remembers seeing the FFFFF showing, normally you wouldn't see this as it takes the monitor about 5 seconds to warm up enough to display a picture. The FFFFF also shows up in an FPGA version of Asteroids Deluxe. So maybe this is indeed an artifact of more accurate emulation with the addition of the ER2055. |

This is probably accurate behavior if the ER2055 is unprogrammed or contains invalid data, as the code doesn't check the integrity of the EAROM high score data before displaying it on screen. The fix for MAME is easy, though: just default the EAROM data to the zero fill the old device provided. |
