*I did try changing VU Rounding to Nearest (like we just added for THPS) but the game would still crash Sad

# Description of bug and of how to replicate it:

Guitar Hero 3 will randomly crash after beginning a song. There are also graphical anomalies in both HW and SW mode which can prevent progress as notes will dissapear, ect..

  • After getting past the intro videos and the autosave screen appears; the console will begin to to spam
    Code:
    Gif Unit - GS packet size exceeded VU memory size!

  • I also spotted this a few times
    Code:
    microVU1: BAL in IBNE delay slot! [3088]  - If game broken report to PCSX2 Team

    Going further through the UI; there are no problems except for a few graphical artifacts in the character selection. After selecting a song you will see various anomalies in both render modes until the game slows down for a few seconds and crashes.

  • The console produces this before crashing
    Code:
    Gif Unit - Signal or PSE Set or Dir = GS to EE

Not sure about the crashing; but the forums say the texture issue have always been present - the only proposed solution was using Skipdraw 2 or higher. I'll test in 1.4.0 later.

This game was also the first in the series developed by Neversoft with an new engine from scratch - so you won't see related issues in previous games.

Had you set your VU round mode to nearest?

Yes I tried that as well. Positive or negative rounding can't be used as there is black screen after intro FMV's.

I just tested this on 1.4.0 stable and it crashes exactly the same. Nearest rounding on stable doesn't crash, but the GS window stops rendering and becomes unresponsive.

No I disabled all of that before I started testing and encountered no difference

Just to check, when you changed the round mode, the spam in the console should have stopped (the Gif Unit - GS packet size exceeded VU memory size! stuff) and you didn't load from a savestate right?

Can you give me an emulog from after that change?

Just to reiterate, that change is needed as it uses the same engine as Tony Hawk

Ah I see what happened. I forgot to reset the EE clamping back to Normal. Tongue

The console doesn't spam anymore and no more crashing. The graphics are still messed up however

Here's a new emulog after playing through an entire song and writing to the mem card: http://pastebin.com/zY3MxZZE

Yeh the graphics are known to be broken in hw mode, you need to use software mode.
