What about software mode. did you test it ?

this is either a VU or a COP issue, not sure which.

Haven't we fixed this once? I think it was VIF1 timing, iirc.

No, the game used to have path3 masking issues, causing flashing textures, but I fixed that ages ago. The game has always had SPS.

Okay, first thing to check is that VIF1 interrupt delay that currently breaks the intro to Shadowman 2 with SPS.

I think I'd already tried that, I did look at this issue for a while and came out with no results.

Couldn't hurt to try it again in case I'm wrong.

Ok thanks you for the quick test.

... This bug is too old, how isn't fixed yet?

I know exactly why it is broken, the game requires tight synchronisation between the EE and VU0, the developers have timed some of the writes to it precisely. I doubt it will ever get perfect, but to fix it requires a whole redesign of how the EE times itself and how the vu's synchronise, which is probably going to cause an impact in speed.

Hmm, I don't know how the ps2 work internally, but this mean is impossible even a game specific hack?

marcussacana on 23 Apr 2020

Likely not, this game is possibly one of the most picky game which require a near cycle accurate VU0 and EE timing.

I understand, thanks for the information.
By the way, if like me, someone played this game a lot in childhood and wanted feel the nostalgia, the game also has for PS3, X360, DS and WII, you can try your luck with other emulators.

This has been resolved on master.
