Gran Turismo 4 Modding Discussion

[Nebuc72]

I wonder if there's some way to change the game into a... err... I don't know how this'll be perceived but... in a no-rules where any car can be be brought to any event.

Reason is that I was playing with GT4's original game version with cheats that made me really enjoy it and I could try all sorta wacky and fun combo's and even bringing underdog cars to some events and seeing if I can still win 'em.

Is there a mod for GT4 that's like that?

Spec 2 lets you do this after 20% completion by pressing R1 on the regulations screen on any event you have already beaten normally.

Hey just checking in, had mod development halted for now or is another update due? Just curious is all. Having a blast 😁

Due this month, my time away from the game over christmas turned into a bit of a longer break where I couldn't really be bothered to open GT4.

The coming update will have a couple of new events, the ability to set laps in Event Synth, a few new sounds, and quite a few car physics tweaks/corrections.

Sounds great! I know the feeling to be honest with some games...so that's no problem. Looking forward to it, I appreciate as always your great efforts!

Dunno if this is related, but I'm working on a super starter save for Asian (SCAJ-30007) and China (SCCS-60002) versions.

The save data includes:
-All purchasable cars ready in arcade mode
-All gold licenses
-Mission races done
-Fully ready-to-race garage (all maker events covered, some personal picks & purchase only race cars)
100% saves are also considered, depends on the reaction for starter saves.

Now all left is a double check to make sure all is ready, and figuring how to record footage.
Big thanks to Nenkai's save editor and assistance from Silentwarior1.

Apologies for the delay, and here it is-the save data showcase video, as promised.

Amazing work as always!! I loved doing a 10 Lapper at George V Paris! Got myself a nice 57,510 Cr. doing so! 👍

Only thing I can think of that is missing would be a Non-Odometer restoration of the cars. Yeah, I got uh... Kilometerage OCD.

New version's finally out:

The patched ISO boots and the MD5 hash matches but 7-Zip can't seem to extract GT4.VOL. "Unsupported compression method" error. Any idea? Previous updates worked fine.
The new Toyota & Pro events are not on the site's prize list yet in case you forgot.

I don't think I've ever extracted the VOL with 7-Zip, I would try using UltraISO since that's what I build it with.

Prizes weren't forgotten, just preferring to keep them off the list until more people have found them for themselves.

New version's finally out:

Re-rolling 10 laps of any special condition (event synth) race draws from the same tiny pool of 3 opponents while 1.08 has more variety. Possible bug?

Nothing has changed in the way it picks the AI cars so I would need more information. Is this in the same car in each case? Is it from one of the road tracks or a dirt one? Which cars does each give you, etc?

My mistake. I meant the dirt & snow event synth races, not special condition. Using Cube EX on any track at difficulty 0 & 10 laps, I'd always get matched with either a Vitz (Yaris) F, a Cube X, or a MR Wagon Sport while on 1.08, there was one of the Beats, a S800, and some other models, definitely more variety than 3. I'm on PS2 if that may be the cause.

can anyone convert this code to GT4 Spec II? Thanks!

 

[TheAdmiester]

^ Already answered via DM but just restating here that there's a built in money cheat that more or less negates the need for this.

Thanks, will look into it for the next update.

Having a real blast. Spec II is amazing. Huge thank you TheAdmiester!!

Only thing I can think of adding more would be a way to restore any car without resetting the KM'age/Mileage. One of my race cars is way worn out at 40,000 KM on the odometer (I used the 16x B-Spec cheat and I went into endurance after training B-Spec Bob. ) but I'd love to keep this as a minor milestone but still being able to restore the car except the Odometer, if possible.

(Quick addendum, because I forget on the spot, Some cars cannot be restored using the paint change because they can't be repainted.)

Hello, I registered to request a little thing for Spec II, but first of all, congratulations for the good job you've been doing so far @TheAdmiester

Now, the request: could it be possible to include an option to not have repeated rival cars when using the 'Specific Opponents' option? I'd like to make a custom league of sorts and keep track of scoring manually, but even limiting the favorite list to 5 cars, the game will pick repeated cars from that list as opponents; let's say I want my rivals to be always the 5 different cars in my list to keep track of easily, but the game will randomly pick repeated rivals, like 3 Mazdas 787 in the same race for example, which makes things impossible for what I intend to do.

Keep up the good work.

Welcome to
Also, I'm kinda surprised and impressed the name Celica was still free after all these years 👍

You can use Nenkai's save editor to reset everything but the odometer. Just deduct the restoration cost from your balance.
I do this whenever I forgot to refresh while tuning/hybriding.
