Known issue.

Thanks

Just curious, would it be possible to do the effect on the CPU and blend the result?

Or is this one of those horribly difficult effects that needs some kind of ParaLLeL-type plugin?

Only half of the effect is rendered, and since it's half we have a crc fix that skips the effect.

Please post a GS dump of the issue. You didn't even include screenshots, so it's difficult to say what's going on.

Sorry bud, recognise the name, well-aware of your contributions...did try to attach GS Dump but GitHub rejected the .gs file, perhaps I missed something

Have changed the file extension to allow upload but FYI the .log are just the .gs files, please find below

Issue itself kinda reminds me of old raster bugs on NeoGeo on KoF... SW: Tekken 5_SLUS-21059_20230618162548.log Tekken 5_SLUS-21059_20230618162514.log HW:

Recording at 30fps via Vimeo, HW render then SW

Sorry for low frame rate but on the recording note (if it's not too cheeky) I have the FFmpeg .dlls in the folder and use the roaming folder setup but PCSX2 doesn't seem to see them

Please let me know if any other info is helpful

Lastly, not sure if related, if not let me know and can open another issue: missing post-process effect in HW on Moonlight level

Regarding the heat effect, it's just offsetting the buffer address for draw back to the main framebuffer. For some reason, whoever wrote the CRC hack decided to just skip the effect, rather than fudging the FBP...

I actually went an implemented a whole sub-target detection thing, which fixed the issue, but broke a bunch of other games.... and many of them are misdetected channel shuffles. I don't really want to add yet another hw fix which only works for one game, so this'll stay on hold until I think of a better way of handling it, or sort out the false positives..

Relevant code is here if anyone wants to mess with it: https://github.com/stenzek/pcsx2/commit/b1e9b739b1d5e2ba71f64a5b58393c81720155d4

thanks, this is a little beyond my v v basic PHP skills but have starting chipping into the project, thanks again for all the time and hard work, the project is far away from what it was now...
