Eboots much like ELFs are the game Executables. Only the .VOL has the game database information within it, which we don't have access to at this point in time.

Exactly. Latest Gran Turismo games have a locked VOL file, and at this point we don't know how to unlock and open it.
I'm pretty sure there are a lot to dig into.

That's a pretty long list I made with all the info's regarding the tracks :)

EDIT : track ID 45: the correct filename is "new_fisco_ps2" , sorry about that small mistake ;)

You can't really do much with these codes, can you?

Basically, there are three track list in the game:
- filenames of actual tracks ( "_ps2" at the end )
- cXXX format. For example, here's a part of these strings: " c046 . . . . Complex String . . . . c047 . . . (Temp)circle60_ps2 . . . . c048 . . . "
- filenames for missing tracks, with in-game name ( without "_ps2" at the end, like daytona, lasvegas etc )

Not all tracks from a list have a connection to the other.
Hong Kong for example have the map, the logo, the picture, and it works (emu only). But the game won't pop out these things when you load it, you have to swap other addresses and not the actual track loader.
Special Stage Route 5 instead have a "_ps2" file but it doesn't work. Others like lasvegas doesn't have it but they still have extra data.

The cXXX is another method to load tracks, for example swapping c008 (High Speed Ring) to c009 (Hong Kong) will make the game load HK by selecting HSR. That however doesn't allow real hardware to load it.

While I was compiling this I found interesting that Tahiti Dirt Route 3 from GT3 ( name circle60_ps2 ) , in the cXXX list is named "(Temp)circle60_ps2".
Gran Turismo 2 version of it ( tahiti_dirt_ps2 ) instead has a proper name there "Tahiti Dirt".

By the way, after this explanation, I must say that this is more like a spreadsheet info.

Is there a way to convert these to work with CW cheat?
I had a track list for CW cheat but I can't seem to find it anywhere.

Sounds like a mix of a GT40 and a 787B with those high revs :lol:

Agree ahah :D
GT PSP use 4 cameras : 0 ( bumper ) , 26 (cockpit) , 6 (roof) , 1 (chase).
Starting from these it's not hard to find the unused ones.

The most interesting one is value 30. It's a cam that you can move, rotate, zoom in- out. Guess devs used it for creating screenshots.

Here's some pretty nice shots.

How far can you move the camera? I'm curious to see how the tracks look (the outside decorations/is Seattle Short still there).

There's a Debug Camera Cheat codes, where you can move the camera freely around the map.
And there's this extra camera which is fixed to the car.

There are some roads from Seattle Short, but nothing too special.

P.S. I took more screenshots and I had to put them together to make this.

Looks like MattJ155 got a special version of GT PSP. Let's see what he can find...
Click to expand...
He had this version since 2015-2016. Hope he'll start to dig into it asap.
As I wrote on that post, that number is the same you can find into game "user manual" first page, but that doesn't mean that this version is the same as the final.

One question, how do i access debug camera for GTPSP? and how to get the black cars?
Click to expand...

_C0 Debug Camera
_L 0x201281F4 0x24100002
_L 0x20128200 0x24050002
_C0 Reset Camera Codes (Do not use on SmnorthPS2)
_L 0x201281F4 0x00A08021
_L 0x20128200 0x10A00016
_L 0x204DDAD4 0x00000000
_L 0x204DDADC 0x0000001A

This is the Debug Cam code , when you enable it you'll be free to move the camera anywhere.
Enable the first cheat "Debug Camera" to use it.
To disable it, you need to disable the first cheat and enable the second one "Reset Camera Codes".

Regarding black cars, at this moment there's no way to drive them.
 
Here a good news for you. After few hours of trials and errors, I managed to find and create a CWCheat code for playing with the unused car colors. Since theSe are CWCheat codes, they will work on real PSP too. You need to enable them before starting a race / time trial / drift, because sometime cars will not spawn.

These are for US version of the game, PPSSPP ONLY.
_C0 P1 Car Color
_L 0x21518A48 0x00000011
_C0 P2 Car Color
_L 0x21518548 0x00000011
_C0 P3 Car Color
_L 0x21518048 0x00000011
_C0 P4 Car Color
_L 0x21517B48 0x00000011

great find!
 
Ok i managed to find the color codes for real HW, which is different than PPSSPP.
Of course you can change the value (11 in this case) to see other colors for some cars.
Enable them in pre-race screen ;)

_C0 P1 Car Color
_L 0x0150F348 0x00000011
_C0 P2 Car Color
_L 0x0150EE48 0x00000011
_C0 P3 Car Color
_L 0x0150E948 0x00000011
_C0 P4 Car Color
_L 0x0150E448 0x00000011
