Searching For Evidence of Hidden Things

[submaniac93]

Well i've gotten the game to know there are more color choices than by default, and therefore load custom/demo palettes, but they're only visible in the manufacturer, so it doesn't help much.

The very first byte in CDP and CNP files is the number of colors present on the file (and therefore on the car in the shop) in hexadecimal. However if you add a color that way, you'll get what I said. You'll be able to view it, but not apply it to the car, because there's something else that needs to be changed.

 

[B_rad88!]

Its probably located with the carcolor files, as when renaming "jet liner silver" to "pistachio green" I accidently used 1 space to many and it cause all the color squares to go full crackhead and glitchout displayed a bunch of random color squares.....


Other wise, your only allowed to use the alotted color squares in dealerships. Any more than the alotted number would have to be its own body. Example, the ford gt90 and cobra coupe betas have multiple colors, but only 1 color squares, so for those cars each color would have to be its own body to show the color in garage.


Also example the 93 eg6 civic si 3door, had "harvard green", I deleted that color coding and replaced it with the tahitan green from gt1, so now the tahitan green will always show up instead of the dark green without issues.

 

[submaniac93]

Well yeah, the game displays only a single color square, but if you were to add a color's data to the car's texture file, after the stock single color, and change the 1st (index) byte to 02, then you'll be able to pick both colors in the showroom, despite only one square showing.

Here's what I mean (here, i showed how I added the beta white color to the Peugeot 106)

https://gyazo.com/fd849840a1c3d64e348a6a4ed8040752

But like I said before, the color can't be bought because something in the game's files (maybe in the carcolor file) prevents the game from allowing it.

Some days ago I bought NTSC-J version of GT2. Today finnaly I could check what's inside the user's guide. To be fair I didn't expect to find something special there (in PAL version of GT2 user's guide there are screenshots from GT1 ), but in this one I find some insteresting stuff, which I'll post here.

Hud looks like in the final version, but there's still beta turbo gauge and map is in Tahiti Road Reverse style.

I'm not sure there's still same font for "Welcome to The GT World!!" inscription in the final version?

There's still beta turbo gauge in split screen mode.

Most interesting one - dealer shop looks very different and there's different background in Licence Centre.

And some things I found in car list:

Here we can see two separated Listers (I think there were plans to make LM Editor of Storm, not the racing modifiaction) and there's still CLK DTM2000.

Ford GT40's still got Mark III part in their name.

Honda Nsx-R had to have as Rm the famous GT2 LM!
x2 Lister Storm. Road and Special Race Version!

Noice!
Would you mind scanning all the pages?
I know its a huge task.

I already did it, but I left PDF file on my office computer so I'll upload it tomorrow.

I've ported all the right files. That's not the issue. The issue is as you mentioned, there aren't enough squares allowing you to select the beta colours despite them loading in the dealerships. So there has got to be a code somewhere that we haven't found that determines the number of squares that populate in the showroom for a particular car. If we can find this code then modify it to allow the square to show, then maybe it will allow the colour to be bought and stick in the garage and race.

 

[B_rad88!]

The colors will stay if modded properlly, look in the past 20+ pages you'll find some of my pictures with beta colors in garage and inrace. Its like how I said, either use the amount of alotted spaced, or replaced select colors, or make each color its own body. Thats how I got around that problem.

 

[JaimePL]

Here it is, NTSC-J manual.

 

[Overload_35]

A microscopic discovery. The name of CLK DTM hidden is also present in the simulation version of the Japanese version 1.0 - It does not appear as a name in the garage, but in the race list, and replay displays its full name.

As you remember in the Japanese version 1.0 in my old video, her full name was also in the garage!

 

[submaniac93]

@B_rad88! @FRR35H

I looked into the car colors thing and found a workaround to be able to buy added colors.

I found 1 new thing from looking at .CDP/.CNP files. As I said before, the first 2 bytes are the color amount.
Next is bytes 02 until (probably) 11 are something to do with the little cubes, or some kind of ID that lets the game decide color names? I think it's for the little squares, however, trying to add a value didn't do anything. I'll have to look into it a little more.

ANYWAY, as I said, I found a workaround the not-being-able-to-buy-added-colors thing.
It's simple. Just make sure to have set one more color on the 1st byte than the actual amount of colors your car has.

So for the 106 from earlier, with the white, it has 6 colors. I set the ID to 7 as a test. And bought the "ghost" shiny color. And surprise! the car was white when I entered a race (but still Silver in the garage)

I also modded in the Beta Red and Blue with White Stripes colors onto the Viper GTS. In the showroom, the Red shows up right before the blue with white color. So I bought the Blue color. Went into a race, and it was Red with no stripes, just as I expected.

So yeah, it's weird, BUT, after the normal colors, the added colors are somehow misplaced by 1 slot. Maybe that can be arranged by having a blank color between stock and beta colors... This needs testing. But i'm pretty sure this workaround should work for now.

EDIT: I just tested to have the blank color before the beta added color, and nope. Doesn't work. Buying the White gave me one of the Blue colors, and buying the Ghost color gave me.... the ghost color. So yeah.

EDIT2: Okay i've tried adding 2 colors to the 106 Rallye (i just copy/pasted colors from the 106 S16) and scratch what I said earlier. You can buy the beta/added colors if you have the Color amount being +1 than the actual amount of colors the car has, but it seems they're in a random order.

I added Red and Yellow to the White the 106 Rally has by default. So White, Red, Yellow, Ghost (empty) color.
However when buying the car, white was white, Red was Yellow (so 1 color forward), Red was White(2 colors back/forward), Ghost was Yellow.
In the end I still got all the beta colors in a race without using any code, but they all showed up as white in the garage, and it invalidated my theory about color placements.

To be continued an other day

 

[B_rad88!]

@submaniac93 Yeah the colors will be "visible" but it doesnt fix the error, thats part of the beta car porting mod.

And the first # square is just so the game knows how many colors are on that palette, then menu color squares I think is in a total different file,


example when renaming the color name error toyota starlet from "jet liner silver" to "pistachio green" when going over the # of hex squares alloted by 1 extra character, all the color squares glitched to different colors....... so I honetly think those menu color squares are located with the carcolor files. (English names{ntsc/u} is in ccspanish file)

 

[JakeMR2]

Not that I found something interesting in Gran Turismo 2 Trial Version, but there are Course Files that don't exist in the later beta. It's in the BGOBJ folder file.

cloudtest
au (What is this in this file?)

I wanted to ask this for a while, and I don't think these series of files are used. Cloudtest I know is not used.

I have a feeling these are in the final as well.
Either way, I think these are skyboxes. Best we can do is load them up by swapping around files.
My best guess is that cloudtest is just what the name says. I dunno about au tho.

 

[submaniac93]

@B_rad88! Yeah I've looked into the color names file and they're all indexed the same way cars for events are. So those can't be changed at all as the game looks for a specific offset to know what string of text to show for what color on that one car.
As you said, it's probably in the carcolor file that we'll find a way to add squares, but i couldn't decipher any of it as of yet, and i'm probably one of the worst to read and understand hex strands x)

But still, even if it's a little scrambled, it's still very possible to add beta colors to GT2 cars

 

[B_rad88!]

@submaniac93 Yeah, I'm having a hard time reading the coding in the carcolor file in hex, but I do see patterens in the first section(the coding) of it..... before the names!


so maybe after starring at it for awhile it maybe might show something like those pictures as a kid when you had to stare at it to see the hidden image......


But in those files everytime I change the name and use to many characters, the color squares all glitch out.... most would turn to the default rx7 aspec green color square.


I also found out there is a size limit to nameplates, 256x72 is the max size I have got to work successfully. It doesn't matter what the standard size was ALL can be upsized to the max!. Also apperently there is a limit cap to how many cars you can add/port to gt2 final. I added about 100 extra cars (total over 700 now) and now tvr and suzuki doesn't work.... so maybe there is a limit cap? I have no clue, about to delete some and try again.

 

[submaniac93]

256x72 sounds about right. I made 256x48 nameplates because that's most likely GT1's resolutions. I'm kinda thinking ahead to hopefully the day we'll be able to mod GT1 ^^

But I might remake GT2-specific cars to a higher res. We'll see. I'll be busy starting next month, so I don't know if i'll be able to work on that or not.

And damn! You added cars? Have you managed to load them into the garage? Like, I dunno, with a buy any car code? Although I don't know how that would work since we don't know the car bodies's codes... but nice! I was wondering if it was possible to add cars to it

 

[B_rad88!]

Yeah, its possible example, car name i.d. codes end with a "n" for street or "r" for race, which in gs codes is 8 and C, so I would change it to "m" or "o" (7 or 9) or "s" or "t" (D or E) as the renamed extra car i.d. code. and then use the gs hybrid body swap code since they are body onlys....

But its seems I've reached a limit to how many can be added as extra/additional cars......

Examples: I have like 4 cobra coupes: race body, street body, and also a dark red only body and a blue only body........ which show up as red or blue in garage and inrace. As well as 5 concept cars, normal body, race body, beta body, custom color set 1 body, custom color set 2 body and My "Venom midnight concept lm edition" body which is half purple and half dark blue! I shared pics of the midnight concept several pages back!






P.S.

Oh on a serious side note, I have to take a break for a while. I do not know when I can get back fully to modding, but for now I can't anymore. Times just got severely rough for me. I will try to keep checking back reading posts, but I'm not going to be as active anymore.

Sorry,

EDIT: my last mod packs to be released soon!

I've added cars too but basically I used the spaces that were left from the cut vehicles, found their ids and GS body codes (you can find these by visiting another site which is easily found by googling gt2 cutting room floor) and I simply just added the new causing those ID names instead of the original. As an example I added the alternative Taurus Nascar body by replacing a missing Daihatsu. When I load up the Daihatsu code, I get the Taurus body no problem. Offcourse you will get the RX7 LM Edition nameplate so you will also want to go ahead and make a copy of the Taurus nameplate files and rename them to match the new car ID to complete the mod.
It's actually a fairly simple process.
I haven't tried your way yet by adding the "m" or "o". I figured that the game allowed only so much memory to the cars that what was originally set in the betas was all you could use. I might give that a try tomorrow with some cars.
Look forward to your mod pack .

That's actually pretty smart o.O I didn't even think of that. I stick to the rules too much xD

Secondary RMs end with s and tertiary RMs (only VW Golf has it, IIRC) end with t.

 

[RandomCarGuy17]

It's been a while since I shared anything in this thread, but I did do something a few weeks back. I finally tried logo swapping.
I also swapped the Audi A3 back into GT2, the A4 Avant now replaces one of the deleted Rufs. Just like the e36 BMW 323i.

 

[NoGoodNames]

Funny, while all of you talk about swapping things, I'm considering making a GT2 beta mod. In fact, this past week I was kinda making a list of stuff to include in this mod...

This mod will only replace stuff in the final game, so some things from the demos won't make it. (e.g. Indi, Monte Carlo), although when it comes to cars I could port some demo-only cars onto cars that I feel are just duplicates of other cars. For example, I plan on porting the E36 323i Coupe and replacing the E46 323Ci.

Also some other tracks from the demos won't be ported due to be being unfinished (e.g. Grindelwald, Rome Night), and others due to skybox limitations ("cough cough" Rome Short).

The other thing I wanted to share was that MattJ155 (though for some reason I get the notion that he's renaming his channel "Matt J") made this cool video showing the connection that the Seattle 2000 track from the later demos of GT2 has to GT2000, starring an LPer that's a favorite of mine, RynoGT4.


BTW, if you all were wondering were I was for the past week, I was in South Carolina watching the total eclipse and hanging out at my great-grandparents' place. They didn't have Internet connection unfortunately, so the only things I've been doing on my phone were games (mostly this highway racing game called CarX Highway Racing).

I'm back now, and tomorrow I plan to continue research on GT2 Test Drive, and then after I finish researching the demo, possibly start work on the GT2 beta mod. Sound like a plan?

 

[B_rad88!]

Secondary RMs end with s and tertiary RMs (only VW Golf has it, IIRC) end with t.

Thats where I got the idea.... lol.


Also to add there is a limit to how many can be added to the folder........ past the limit it starts to neglect the cars starting from the bottom!

 

[NoGoodNames]

So I went through Mazda and Mazdaspeed cars on the Test Drive Disc today, but this will be a short post because I did not find many interesting things.

The Mazda Familia / 323F S-Wagon was called the S-Wagon Sport 20 originally:

Did Polyphony spell package as "Paceage" in the Mazda Roadster 1.6 logo? I can't tell since it's kinda small...

The Mazda RX-7 GT Turbo '83 is incorrectly referred to as the RX-7 GT-X by its logo, which is reused from the Savanna RX-7 GT-X '90:

And that's literally all I found that was somewhat interesting to me.

 

[submaniac93]

Yup, once again, JP nameplates. The Familia Sports 20 is still present in the final and the Roadster one became what's known as the hidden miata's plate. I don't think they reused that particular name plate for the final model.
When you get to mitsubishi, you'll find that there are 3 different Minica plates, when there's only 2 Minica models.

 

[Overload_35]

That Mazda Mx-5 logo is used in the little trophy car in GT2 Full

 

[B_rad88!]

Those aren't the only odd nameplates. Like the toyota mrs nameplates, oh can't forget the random reused gt1 nameplates.... I have found a few, like the trd3000gt nameplate is exactly the same as gt1.

Speaking of gt1 nameplates...... ever notice how the mitsubishi evo 3 uses a evo 4 style nameplate, but the evo 2 uses a gt1 evo 3 style nameplate? So needless to say I had to use the gt1 evo 3 nameplate in mine just to mix up some more. Also the nismo font script changed from gt1 to gt2 but I guess thats obvious........I like the older style nismo logos better.......


Edit: forgot also noticed in Opel dealership, the menu pic for the vectra uses a beta "soft" bumper model, like early demos vectra. Also the subaru legacy wagon dealership menu pic uses a beta legacy thats available in one of the demos, but the wheels are off alignment. That legacy also contained 2 extra colors.......

And forgot: the mazda protege gtr rm and protege gtr rally car have nighttime glitches in final, the front bumper is glitched out. Also the beta nissan pulsar vzr n1 (with side decals) doesn't even have a front bumper at night! Talk about major fail!

 

[NoGoodNames]

Other things I noticed:

The Lexus IS and Toyota Altezza RS200 seem to share the same picture for some reason...

The Subaru Forester has beta rims in its picture:

I noticed two things in Arcade Mode too. This first one is pretty easy to spot, High Speed Ring's preview video is set at sunset like in GT1 Test Drive:

You might need a good eye to notice this next one though. On Red Rock Valley's video preview, if you look very closely there are billboards which say "GRAN TURISMO".

In the actual game though, they say "GRAN TURISMO 2".

In fact, not many tracks in GT2 don't have a GT2 logo anywhere, and instead have normal GT logos. It's mostly the tracks from GT1, but even then a couple GT1 tracks were updated to have GT2 logos!

 

[NoGoodNames]

Did more GT2 Test Drive research today. This time, I went through the British cars, but the only manufacturers where I really found anything interesting were Lotus and Vauxhall.

The Lotus Elan S2 '90 was called the Elan SE, and in the demo it has glitchy modelling and misplaced wheels.

The TVR Cerbera LM Edition also has glitchy textures in this demo:

The Vauxhall Calibra Touring Car was called the Calibra DTM '95 originally. Same thing probably goes for the Opel version.

The Tigra Ice Race Car was called the 1.6i Chamonix too. Again the Opel version likely had the same name.

And here's the logo for the Opel / Vauxhall Vectra 2.0 16V:
