| Summary | 0003125: Z-Out highscore list doesn't work on WinUAE | ||||||||||||
| Description | I don't know if this is the right place to report this as I don't know if it's a whdload problem or a WinUAE bug, but here goes: Z-Out's highscore list works on my real Amiga, but it doesn't work on WinUAE. I have tried a few different WinUAE-configurations, but the highscore list is always broken. The shown letter doesn't correspond with the highlighted small letter, it's difficult to choose OK and Z-Out thinks the disk is write-protected (when it's not!). Thanks! | ||||||||||||

Are you using lastest slave version? Because there were fixes regarding the highscores. |

I'm using the latest WHDLoad version (18) and the latest slave version (3.3) on both WinUAE and on real hardware. So I was surprised to notice that it works on one but not on the other. I changed WinUAE's chipset settings, memory settings, everything - the highscore list stays broken. |

I would recommend to ask at http://eab.abime.net/forumdisplay.php?f=5 because it seems to be a uae only problem. |

OK then, thanks! |

I've tested on WinUAE and I confirm the issues. - hiscore positionning is off by 4 chars - disk seen as write protected - also stars are not that random and the effect is lame works on the real machine (what the hell!!) |

(Apparently I was never contacted) Title screen has multiple problems: - Advantec logo is horizontally shifted if OCS Agnus (Original game works exactly opposite, it is only correct if OCS Agnus. So "Advantec logo recentered" broke it if OCS Agnus) - small text writer is 1 scanline too low if ECS/AGA. - small text writer is horizontally shifted if ECS and only if ECS Agnus. All problems are caused by buggy copperlist that enables/disables bitplane DMA when DMA is about to start. This causes side-effects and OCS/ECS behave differently in this situation. Fix probably is as simple as moving DMACON bitplane disable copper MOVEs horizontally to earlier position. WinUAE handles these 100% correctly, just change chipset type on the fly to see the difference. And finally, AGA side-effects apparently are not exactly same as ECS because real AGA hardware shows small text writer in horizontally correct "OCS" position (but still 1 line too low). Unfortunately there are multiple reasons that can cause this difference and I can't be sure which exactly causes it (without breaking anything that shouldn't break) without more testing first. -- Write protection issue is almost guaranteed to not be directly emulation related. Stars: use more accurate CPU mode? |

Toni I was about to post something on EAB about this, but in the meanwhile I ran the cracked version with WinUAE and no star issue (didn't test the rest) Your explanations are invaluable, and I realize now that at least the "advantec center logo" fix shouldn't be applied when OCS Agnus found some code on EAB: http://eab.abime.net/showthread.php?t=72300 to detect AGA. The stars are (more) random once you played a game and lost. I'd prefer fixing this in the whdload slave, but that's probably too much work. |

It probably is best to fix the copper list so that it works with all chipsets without separate chipset-specific fixes. I can do it while trying to understand whats the (previously not known) difference between ECS and AGA. This game is good test case :) Star field probably uses usual stupid read $dff006 for generating "random" numbers which returns very static numbers if CPU is very fast without chipset DMA slowing it down. |
