Gran Turismo 4 JP Assertion Failed
#1
Hey everyone,

So i've been playing my copy of Gran Turismo 4 I bought off of ebay and got since yesterday and everything has been working fine. I just went over to IB-5 (206 RC 1 lap guided run) and as it loads it gives me this Assertion Failed error:

D:\Git\pcsx2_master\pcsx2\FiFo.cpp(48) : assertion failed:
    Function:  ReadFIFO_VIF1
    Thread:    EE Core
    Condition: vif1Regs.stat.FQC != 0
    Message:  FQC = 0 on VIF FIFO READ!

I don't know what to do as my other 3 PS2 games I own doesn't do this. Any help would be appreciated. Also here is what the settings I have set for PCSX2:

PCSX2 V1.6.0

OpenGL Hardware

Internal Resolution: 1440p 2k

Everything in the preset wise for video settings stuff is set to it's default settings

Please post the contents of the emulog.txt file after the problem occurs. The file can be found in "My Documents\PCSX2\logs" for the installer version or in "PCSX2\logs" for the portable/binary version.

Please make sure to enclose your emulog in code tags like so (remove the empty space on the closing code tag!):

So I somehow got it fixed by messing with the clamping mode and round mode. I was just messing with it and somehow i was able to get passed that error. Seems as though setting EE/IOP clamping to Full and VUs Clamping to Extra, while setting EE/IOP and VUs round mode to positive was able to fix it if I recall. Then I just swapped it back and everything works now. I will say that the emulog got cleared out when I got it working again sadly. So this thread can be closed, sorry for the inconvineance.
