Shin Megami Tensei: Persona 1 - title screen shown during later fadeouts (missing readback). Similar in Persona 2 #13079

In smt persona when a battle is initiated it shows the the title screen during the break away transition instead of showing the spot the player is currently at.

Below are images of what it's supposed to look. []()http://imgur.com/a/0cYhUx8

I also noticed that if you've made a save state it will use the thumbnail of the save state too.

Can confirm this in Windows build, v1.10.3.

I believe this still might be an issue, we're missing some copy or readback or something...

Does this work as expected in software rendering?

A similar issue happens for me in both Persona and Persona 2 Innocent Sin. Instead of the title screen, it either shows:

Can confirm that software rendering fixes the issue in Innocent Sin. Have not tested Persona (it runs noticeably worse in software rendering).

Honestly, based on the savestate thing, I'm wondering if this might be a double-buffering issue? I don't know much about the PSP architecture though, so take that with a grain of salt.

Pretty sure the game does some copy from VRAM that we fail to detect, so we end up using "old" data instead.

Isn't this the exact same issue/similar I reported on #18262? By that I mean that fixing this might fix that other issue too.

Reading the description, they seem to be the same issue indeed.

Hopefully when this one is resolved it can fix the ones on Stein's Gate. It probably affects other VN's and games like Remember11, Ever17, Hakuoki Demon of the Fleeting Blossom and such.

I wanted to report this happening in Kingdom Hearts Birth By Sleep Final Mix too. Everytime there's a fade out effect some other menu is shown during said transition.
