The game is marked as having imperfect graphics, and the driver notes indicate that emulation is not correctly done. That having been said, I don't see any particular issues with dead enemies, so I cannot confirm at this time. Also, do not tick 32-bit specific and 64-bit specific together. Only choose one OR the other, and only if you confirm it happens on one and not the other. |

Yes there are 1px gaps between some zoomed sprites. Sprite coordinate rounding with zoomed sprites is not 100% accurate in konami sprite chips emulation. I tried to fix it but couldn't find the exact method (I can improve this game, but make another game worse) same bug as: https://mametesters.org/view.php?id=258 and also related (different sprite chip, but similar zoom algo): https://mametesters.org/view.php?id=1076 lethal enforcers (Japan version?) PCB: In the video, I see no sprite gaps on enemies, but I do see them on car doors during car chase scenes. I don't know what his flipscreen options are (yes it matters) HD quality PCB video of Asterix: 1-frame sprite gaps on scaled title screen logo, similar to MAME, not exactly the same. We'd want to emulate it to match the glitches visible here. |
