Im having an issue with Gran Turismo 4 not loading after updating to the latest 1.2 build.Getting a endless black screen after the copyright screen. The dump matches the MD5 on Redump. Tested on a modchipped 75004 with FMCB and non modchipped 9004 with FDVDB.
 
Try using another upload medium (SMB).

Personally I recommend using the stable version OPL 1.1.0

Also try activating mode 6 in the OPL options for the game.

Strange thing is... I have the same problem in GT4 (plus in Tekken 5 game freezing sfter mini game) with lastest few betas. But when I`m trying use older verions (0.93 or 1.1) booth games stuck exactly at the same moments.
Before updating and using latest betas GT4 worked OK, now not working on any OPLverion . ???

Update:

I used eveything. Finally after deleting OPL folder from MC and set all options again I was abble to start GT4 with ancient 0.8. version. After that I was abble to start game with 0.9.1. Nothing above is working...

What medium are you using, USB, SMB, etc?

Try doing a clean installation of OPL.

It happens that when changing versions, anomalies may occur.

Also observe the configuration in the game modes that are not activated, try first without the modes, then try activating especially mode 6 as I told you before.
 
I`m using SMB server on mini pc connected by cross cable. All proper modes for my all games are activated. Every games worked great before I used some of latest betas.
There is information on the OPL Loader git weebsite that there is a problems with dvd9 games not solved yet. Latest recomended is 1917. Interesting is how use that latest betas has an impact on other versions?

That's right friend, some games improve in new versions but others that worked before stop working so you have to go back.
 
Are you using PADEMU?

Just from my own experience, I get the black screen freeze if I connect my DS3 before the memory card loads..so I just wait until the opening video shows before pressing connect on the controller. Might not be your issue, but I have seen this specific to GT4
 
This is a long standing bug with OPL on this game. It may have to do with seemingly using a compressed ELF. Though someone told me on GT Planet that it uses (or has a lot of) relocatable code.

@gamerman5000 yeah, but now I can`t use anythin above version 0.9.1 for that two games. Every time freezing at almost same moment. Plus if you take a look on the pc LAN connector diode you can see that it stops blinking (stop loading).
Maybe i will try to use other Memory card and configure everything again for version 1.1.0...

Some games that do not work on SMB work on USB and Visceversa.

Also check the compatibility list.

Edit: check that you do not have a VMC created, when they are not compatible they cause the game to never start.

Tekken 5 has worked for me with the American region in opl 1.1.0.
 
After many attempts I solved this strange problem (in my case offcoz). Games is working now with 0.9.3, 1.1.0 and beta 1.2.0 r1917 (last recommended because newest have a issues with many games).
Old 0.8 version save all his data on MC. The new ones use a media source (USB or HDD in the case of an SMB server).
In my case i changed PC for new one, updated Windows XP to WIN7 and used one big HDD instead two small. All cfg files copied and splited into one folder. After that OPL is not able to save (overwrite) configuration for each game (if already present) and it can`t load configuration so always loading games with all special modes OFF. So I deleted old cfg and now I can save it and before playing cfg load as it should be.
In your case, in OPL, first check if cfg is set for that game or try to overwrite old configuration. If you get a write error it may be same situation.

Maybe i'm too late but i had the same issue with GT4. Opl version that i used was and still is 1.1.0. And proper dump of GT4
NTSC dual layered disk got stuck every time on loading. Workaround was to use image with compressed video, size about 4.5 gb, so it fits on one layer.
 
Have You tried what i wrote above?

GT4 US working for me on 1.2.0 beta with mode6 ON (via SMB)...

UPDATE:

If you migrate files from disk to other (under Windows) copy all files "with NTFS permissions"...

No, i have not. But i have settled with what i got. Game works, this image with compressed into. And i'm OK with it. I fiddled with GT4 last year just out of curiosity without intention to play it out. To remember good ole days and to look at 1080i on my ps2.
Still got license disk but from PAL region. The one that i played all this years ago. Sorry for offtop. It's just ps2 for me is such a piece of childhood and such.

PS. I'm still using stable OPL 1.1 and not 1.2 beta. As i got bad mileage with 1.2 year ago. 1.1 works back then much more reliable. Is there reasons to upgrade now? 1.2 still looks like in beta stage and i'm too lazy to be myself a tech support now-days.
