Needs research for the reason of this problem.

Savestates with 1.7 build: https://mega.nz/file/FoZ0AJCC#PxH7OP0CZrqqfq38bEbmq5hBhfMxVqTcw3gX9Tan7cU

Still needs research from me but basic idea is there is no TS, instead post-process is done on the EE and done it two halves. a 16 bit depth buffer is repurposed as a scratch buffer to upload to the EE (this is the last thing done, so they don't care if they destroy it).

Bottom halve is classic cache issue, game increments the base pointer to do the bottom and the cache can't deal with it.

Still an issue in 1.7.2731 even in software it seems to break.

user confirmed on the forum that it's still bugged. https://forums.pcsx2.net/Thread-Bug-Report-1-6-0-Suikoden-3?pid=638419#pid638419

There is weird stuff going on in this game though.

I tested it a few weeks ago and it wasn't quite as bad as before (no stripes, just grayscale on the top half and color on the bottom).

yeah, it's doing the shuffle in two halves, so the top half works, then the bottom half misses and doesn't happen.

at least in this scenario

We could use some GS dumps if people want this fixed :P

ah thanks, I hadn't rechecked the forum post :)

Flashback scene is supposed to be black and white, i checked a Ps2 playthrough. Software now shows flashbacks correctly, Hardware renderers have color that isn't supposed to be there. That graphic corruption happening in software too is alot less now, but it's still there.
