Gran Turismo 4 Modding Discussion

[FRR35H]

I don't really do any hybridding so I don't have any plans in that regard. As far as I know hybrid "codes" are just car part IDs from the database so I'm sure someone will figure something out in time.

Yep that's all they really are and I'm sure there are some for the Online Beta that should work, though I've yet to come across them personally.
Does that mean something like an implemented engine swap function in game is not possible without codes?

I have some codes ported over from Retail that I made. But have not posted them out of respect for @TheAdmiester and the others who have made this mod possible.

As far as RAM codes go, I have one that can change the Turbo kit in the currently selected car. As far as I know either the Peugeot 205 or the Renault rally car has the highest percentage gain. I used to think it was the 3000GT VR4 but found out otherwise.

As long as it would not cause offense, I could post them. But as I said, I do not want to cause upset from anyone.

Pretty much, while the engine is in fact a "part" and can be swapped between cars with hacks like hybrids, it doesn't have the category defined, which is what the game uses for being able to natively switch between the usual turbo, exhaust, NA upgrades etc., so it's a no-go in terms of official support.

Would you be able to private message them to me?
I too won't post them out of respect, then again, Hybriding is no secret so I assume eventually the codes will come out.

That's what I thought. Was only curious as you managed to do the drivetrain swap, but as that's just the VCD doing the work I can see how it's possible but not the Engine swap.

@TheAdmiester

First of all, thank you for your (and all other team members) work. It really transformed GT4 in a good way and breath new life into it. All the changes and additions are well-thought after and in the spirit of original.

A few questions:

1.
Since it was possibe to port Valencia track from Tourist Trophy, maybe it is in the realm of possibility to port GT3 tracks also? The ones that didn't appear in GT4 afterwards:
-Special Stage Route 11
-Tahiti Circuit
-Smokey Mountain
-Rome Circuit
-Super Speedway
-Complex String

Similar question about the cars, but in reverse.
GT PSP and GT5 had quite a few "standard" GT4-quality cars, that are absent in GT4 (I know, that some of them were region-specific cars from varios GT4 versions and you have already included them in Spec II, the cars in qustion are the new ones).

GT5 "Standard" Cars That Were Not In GT4...

In the NA version... The Mitsu GTO's are GT3000's, The Oullim is the Proto, The Mazda Cosmo's are 110's, The Vauxhalls are Opels, The Viper 51 is 91... So, they are not all included here cause they are basically the same car duplicated, although the Opel Vauxhall and Vipers livery are a bit...

Do you have some kind of "roadmap" for future Spec II updates? Yes, I fully understand, that you want to keep some features and additions secret, so there will be a factor of surprize. But maybe you have some plans for the mod that you may share publically from time to time?

A few questions:

1 and 2 aren't possible, for 3 I have some plans but nothing concrete. Usually it comes down to more events, more sounds, and sometimes random new ideas and inspirations.

Thank you for the answers! New events and sound are always welcome
Oh, one more thing: maybe checkboxes for owned cars in Used Car Dealerships?

Any chance for more of these codes to be ported to the Online Public Beta?

For those with knowledge in coding, why are the mastercodes found from Spec II ISO different from the OPB ones? I used the mastercode finder and was given 2 different sets of codes.
Any idea why I couldn't get the max B-spec skill code from that JP list to work with any of the mastercodes? Using CheatEngine on a real PS2.

RAM addresses can sometimes change. Version 1.0 to 1.05 RAM codes worked, but when the extra VCD additions were added for certain cars in 1.06 the offsets changed. ASM codes however, seem to stay.
