Kingdom Hearts HD 1.5 ReMIX [BLES01897]

Hi, i've been playing this game without any problem until Agrabah World. When you have to fight against Jafar the second time I can't see anything, only the interfaces like VT, MP... In a crazy try, fighting with a black screen I could beat him. But in the Little Mermaid World the problem is back, and this time I cant do anything. Can somebody solve this problem??

PS: sometimes the audio is muted too.
PS2: sorry for my English, is not my primary language.

Hi, I'm having exactly the same problem on KH 1.5 even with the latest updates :
when coming to the agrabah's 2nd part of the boss, i still have the sound (sometimes not) but the graphics usually stays on a frame previously generated : last checkpoint, entry into a new map sector, the interface with HP / texts remains, I can even have a target on the enemy, but graphically the frame stay frozen.
First time, vs Agrabah's boss I updated the game and it worked, but i meet exactly the same problem in atlantica, where there shall be a graphic effect of "underwater" :
The first times, graphics froze just after coming in the world, with still sound and interface displaying,
Updating didn't fixed this time, after making a few changes, (if I remember well, i changes PPU and SPU to Interpreter (Precise), put firmware settings on "automatically load required librairies", i checked "hook static functions", and in the GPU options i checked "Strict rendering mode", "disable vertex cache", "write color buffers") and i achieved to launch to "incoming in the world" video, and save my game from this point.
When i launch that savegame, i'm able to re-access the menu and save options, but if I leave the initial map area tho the nearest one, entering the menu makes the graphics crash again.
I don't know what to do, i may try previous versions of RPCS3 to see if it works better
Thanks for any help !
