[BUG?]: SPS in TAZ WANTED start menu sign

[janitor-raus]

Describe the Bug

When pressing START in the game, the sign breaks into pieces that fall out of view. Sometimes, these sharps appear afflicted with SPS. The reason this is a "BUG?" is because this might have happened on the PS2 as well, I can't be certain. It certainly is tricky to make the sign break in a way so that the pieces trigger this.

To clarify, this occurs in both hardware and software. Upscaling is irrelevant. I attempted all clamping/rounding modes to no success. Turning speedhacks off did nothing. I also attempted all the manual game fixes but still nothing.

Here's a quick recording:

And here's the dump. Ignore the weirdly yellow water. It doesn't happen in the game, only in the dump for some reason: https://www.mediafire.com/file/vp5k2laipjq330d/gs_20220528014308_Taz+Wanted_SLUS-20236.gs.zst/file

I think I might have tried that combination, but I'm not sure either. I have noticed though that the EE/VU0 settings and rounding/clamping settings appear to have been either removed or hidden in the latest versions' emulation settings so aside from emulation speed, I'm not quite sure how to adjust the rest.

@coornio are you able to retest this?

[janitor-raus]

I imagine you want me to re-attempt it from scratch? For the dump itself still exhibits the issue in there.

[MrCK1]

Yeah I think that would be best. If it's a core issue then a GS dump likely won't be affected

[janitor-raus]

It seems that it still happens.

Just in case, I'll clarify once more that I'm not even sure if this situation is reproducible on the real hardware. I imagine it isn't, considering there's at least one other game that I'm aware of where geometry points get cooky at certain camera angles..

I checked with @F0bes gsdump tool on Ps2 hardware and that "sps" is still there. Also, i checked on Youtube and this video clearly recorded on Ps2 hardware shows the exact behaviour. I think it can be closed as reproduced on hardware
