Doesn't this game require a USB peripheral? Is it possible it's failing to start because it's not detecting it? Has it ever worked? I don't see it in the compatibility list.

Assuming it has never worked then yeah back to my original point about the peripheral.

[Nobbs66]

I did some research on the game before posting this, and it seems people have been able to play it with a regular DS2 like you can Guitar Hero.

@Nobbs66 with a dual shock on the real PS2 I take it?

Then hmmm. I got nothing :)

Edit: Wait, it still could be TRYING to detect it and wigging out when no USB replies. Has anyone tried with a USB plugin?

@Nobbs66 : that's the wrong thread link (before it was pushed ). correct link is here: http://forums.pcsx2.net/Thread-Pushed-DJ-Hero-Black-Screen

edit: oh, btw it would be nice if you could reformat the bug report to something like this #913 by using bold tags for titles following the Git markdown format. sorry for the nitpicks :p

From my quick 5 min testing the game seems to have been broken somewhere between 9th March 2009 to 25th June 2009. Will check further after about an hour.

[Nobbs66]

hmm, do it broke in an old SVN?

A dev will need to get the code. I'd love to help, but I'm not sure what I can do to help find the first broken build.

[prafullpcsx2]

@Nobbs66 : Don't worry, I am onto it. :)

Edit: one of these may have broken it

@refractionpcsx2 : I am pretty sure you can fix this. r1257 seems to break it

https://code.google.com/p/pcsx2/source/detail?r=1257

I noticed that r1257 also broke timesplitters 2 in a similar manner. Timesplitters 2 was later fixed in r1289 but DJ Hero remained broken.

Also I doubt that the game will work anyway even after the fix, it gets to menus only with lilypad in guitar mode and it still requires turntable controller to play the first level.

[refractionpcsx2]

Thanks, I'll look in to this at some point soon.

[refractionpcsx2]

Bugger, can't tell what code it was anymore :( Stupid google.

[willkuer]

Google is not saving the code anymore?

Maybe the comments to the commit lead you into the right mood to remember what you did there?

[refractionpcsx2]

hmm does DJ Hero work with the EE Timing Fix by chance?

@willkuer that did help a lot, thanks :)

[refractionpcsx2]

@Nobbs66 still waiting for you to say if the EE timing fix made any difference?

[Nobbs66]

Oh crap, let me charge my laptop and test.

thanks :)

[Nobbs66]

@refractionpcsx2 Just tested the latest build, and it's still just a black screen

[refractionpcsx2]

With the ee timing fix?

[Nobbs66]

Yes, the EE timing hack still doesn't help

[refractionpcsx2]

Curses, ok thanks for checking :)

[refractionpcsx2]

I'm not sure I can fix this easily. The game fills up the GIF FIFO with GIF Path3 stalled, expects that to all be ready for when Path3 is unmasked (stall is released) and starts another transfer before it gets to the unmasking.

Currently I either lose the data (which breaks it completely, similar to the black screen you currently get, caused by another hack in there for Wallace & Grommit) or it hangs waiting to transfer that data.

Beyond adding a Path3 FIFO which we're trying to avoid for performance reasons, it's going to be a nightmare to fix..

[Nobbs66]

What type of performance hit would we see with a Path 3 FIFO?

[refractionpcsx2]

What type of performance hit would we see with a Path 3 FIFO?

I have no idea, it'll be slower than it is now, it might be insignificant, it could be huge, depends on how much it's used, that's all I can say :/

[refractionpcsx2]

Can anybody who can actually play this (or get further than the no controller screen) can you please try PR #1331 ?

[prafullpcsx2]

It boots fine now but someone needs to emulate turntable controller to make it work ingame. Guitar controller can only take you as far as the stage selection screen.

[refractionpcsx2]

ok well I'll mark this as closed once the PR merges, but it would be nice if somebody can get further, if the guitar controller works, that will do for now ;p

Well, the PR has been merged, so you can close it now. :p

[refractionpcsx2]

Oh yeh, forgot about this :P
