Emulation of the PSX GPU is marked as imperfect (https://github.com/mamedev/mame/blob/master/src/devices/video/psx.h#L39) so it's expected that games that use it may be showing graphical artifacts. |

Firstly, PlayStation video hardware can’t display sprites, it only draws triangles. Secondly, MAME’s emulation of the PlayStation GPU is marked as imperfect, so you should expect to see graphical imperfections. We display those warnings for a reason. Do I need to get rid of the option to skip repeated warnings to stop people from ignoring them? A video from an actual arcade board obviously won’t show artefacts of imperfect emulation because it isn’t emulated. |

When MAME drivers aren't very preliminary, and enabled the imperfect sound/graphics flags, I don't really mind bug reports for them. Even though MT rules say you shouldn't. MAME doesn't have such rules either, like "Don't add a TODO list if the driver is marked imperfect". I'd prefer a well written bug report though, the description in this one is bad (vague), but I guess PCB reference makes up for it a bit. Recent example: https://mametesters.org/view.php?id=9240 - driver has imperfect sound, I think it would have taken us longer to fix it without a bug report and pcb reference. |
