Gran Turismo 2 is essentially just the first game with minor tweaks made and the amount of content cranked up about eight notches.

The game was notoriously rushed to meet the Christmas deadline, leading to a significant amount of content being cut. It’s also extremely buggy, to the point where a bug rendered 100% completion outright impossible. Not that this stopped the game from being a monster hit anyway - the only games on the console that outsold it were the original and Final Fantasy VII.

As an aside, it’s also the first game to be supported by the "bleemcast!" emulator project.

Also, that GT40 in the Historic Car Race for Rome Circuit.

Unused Courses

To do: In addition to l_20 - bill_checker (19), checker (1C) (both US/EU only), test_20a (69), test_30a (6A), test_40a (6C), test_hs2 (6F) and test_l1 (74) seem to be unused. Video documentation is welcome.

Hidden away in Gran Turismo 2 are three unused reverse versions of various tracks in the game.

Reverse Tracks
Track	Notes
	PAL: Set 0AF260 to 2B when the race starts to load. Or set 1D58CC to 35E9 and 1D58CE to 454B during the pre-race menu. NTSC 1.2: Set 0AF230 to 2B when the race starts to load. Or set 1D589C to 35E9 and 1D589E to 454B during the pre-race menu. Laguna Seca Raceway has an unused reverse version in the game. The real track itself was not designed to be driven on backwards, so this is likely the reason this variant was not used. This version uses earlier road surface graphics, and has two replay cameras defined. There is also no AI pathfinding. Additionally, you can not pit in on this track either.
	PAL: Set 0AF260 to 4B when the race starts to load. Or set 1D58CC to 051C and 1D58CE to 353A during the pre-race menu. NTSC 1.2: Set 0AF230 to 4B when the race starts to load. Or set 1D589C to 051C and 1D589E to 353A during the pre-race menu. A reverse version of Test Course. The track is mostly complete with the AI pathfinding almost finished and having its own unique replay cameras with the exception of lap 3 not having any. The AI can not overtake each other on this track and you can not pit in as well.
	PAL: Set 0AF260 to 5F when the race starts to load. Or set 1D58CC to D631 and 1D58CE to D141 during the pre-race menu. NTSC 1.2: Set 0AF230 to 5F when the race starts to load. Or set 1D589C to D631 and 1D589E to D141 during the pre-race menu. The reverse version of Super Speedway. Unlike the other tracks in the game, this track has a different starting grid layout. Just like with Laguna Seca reverse, there is no AI pathfinding and you can not pit in either. The track has its own replay cameras too.

Two further tracks named l_20 and dart_test2 weren't removed from the game and yet aren't accessible to drive on without a cheat device.

The other two tracks
Track	Notes
	PAL: Set 0AF260 to 23 when the race starts to load. Or set 1D58CC to FCB0 and 1D58CE to 01B5 during the pre-race menu. NTSC 1.2: Set 0AF230 to 23 when the race starts to load. Or set 1D589C to FCB0 and 1D589E to 01B5 during the pre-race menu. l_20 is an invisible slalom license test track. The collision is present despite being no modelling present here. No AI pathfinding is present, so the AI cars can not race properly here. The track also has its own course map.
	PAL: Set 0AF260 to 20 when the race starts to load. Or set 1D58CC to 1C8A and 1D58CE to 4EFE during the pre-race menu. NTSC 1.2: Set 0AF230 to 20 when the race starts to load. Or set 1D589C to 1C8A and 1D589E to 4EFE during the pre-race menu. dart_test2 is more substantial in terms of content despite having no course map of its own (the game defaults to the Autumn Ring map). The twisty track actually forms a complete lap though any AI cars present cannot navigate around it. The track uses the evening skybox from Red Rock Valley Speedway, and the road's surface (determined by the drivtype file) is considered as dirt by the game (hence "dart" on the title, a romanization of the katakana ダート). A track map of this course is available here.

Unused Graphics

The following graphics are unused on both discs.

Demo Title Screens

Found in gzip archives in the arcade directory of GT2.VOL are two leftover title screens from demo versions of the game.

Japan/Europe (arc_topmenu)	North America (arc_topmenu_usa)

Early Communication/Data Transfer Panels

Early graphics for the Communication/Data Transfer menu options can be found in the final version of the game. The used version features different art and is smaller in height.

Unused	Used

Indi Leftover

Indi, a track shaped after Indianapolis Motor Speedway, can be accessed through hacking in demo builds of the game. The track was mostly deleted in the final game, with its only surviving asset being this background texture.

License Test Minimaps

Minimap files for the various license test tracks exist, but go unseen as the map isn't displayed during tests earlier than the Super License (which only uses regular courses). Many of them are crudely drawn so they form a complete loop, even though they're simply "track sections" in reality.

• 

  L_circle30 (circle30, B-4 test).

• 

  L_circle80 (circle80, B-5 and IA-1 tests).

• 

  l_20, same as L_slalom20 (test_20, IB-6 test).

• 

  L_slalom40 (test_40, IB-8 test).

• 

  L_corner-brake (test_cb, A-2 test).

• 

  L_Eau-Rouge (test_hs1, IA-2 and IA-10 tests).

• 

  L_J-turn1 (test_j1, IC-1 and IC-2 tests).

• 

  L_box (test_ko, IC-3 test), same as L_box_brind (test_ko_brind, IC-4 test).

• 

  L_L-turnR (test_l1), same as L_L-turnL (test_l2, A-5 and A-6 tests).

• 

  L_S-corner1 (test_s1, B-9 and B-10 tests).

• 

  L_S-corner2 (test_s2, A-7, A-8, IB-3 and IB-4 tests).

• 

  L_U-turnL (test_ul1, B-6 and B-7 tests).

• 

  L_U-turnR (test_ur1, A-3 and A-4 tests).

• 

  L_double1 (test_w1, IB-5 test).

• 

  L_double2 (test_w2, IB-7 test).

• 

  L_crank (test_z, A-9 and A-10 tests).

Unused Text

Platinum Prize

A text string present in gt2.vol shows that it was possible to earn a fourth prize in the license tests. It is even translated to other languages.

PLATINUM PRIZE!
MEDAILLE DE PLATINE !
PLATIN!
PLATINO!
¡PLATINO!

Check Grid

Another text string inside the game also shows that a feature to check the starting line-up in the post-race menu, much like the original Gran Turismo, was meant to be included.

Check Grid

Unused Music

There are two unused short jingles within the game, which might be an unused alternate race start and finish jingles, respectively.

Unused Tuner IDs

"Tuners" are what the developers define manufacturers and brands in the games; in this game, it defines which car goes to which dealership for tuning (the game will throw a "Your car cannot be tuned here" error message if the car's current tuner and the dealership's tuning shop mismatches) as well as used car listing definitions. There are 36 tuners defined in the game, stored in alphabetical order; however, there are three tuner IDs that are not used by any car in the game:

• 0C - located between Honda (0B) and Jaguar (0D).A possible candidate is Infiniti, which has trackside advertisements despite they appearing only in the US version of the game as a name swap for the Nissan Primera sedan models.
• 0F - located between Lancia (0E) and Lister (10). A possible candidate is Lexus, whose cars are sold and tuned in the Toyota dealership in-game. Of note is that this ID was not documented in the source mentioned below, although the other two are documented.
• 14 - located between Mercedes-Benz (13) and Mini/MG (15). A possible candidate is Mercury, whose cars are sold and tuned in the Ford dealership in-game.

Texture Tags

A few car textures are inscribed with the word 'polys' in out of the way or unused portions of the image. This refers to Polys Entertainment, the original name of developers Polyphony Digital. It should be noted that these texture tags appear too in the previous game, since these cars originate from there with no significant changes to GT2 except for updated rims.

• Polys Academy
• 

  Most non-racing NSX models, both Acura and Honda use copies of this sheet, and the writing is on them all.

• 

  Mitsubishi FTO variations have a smaller rendition above the mirror on the side-on portion.

• 

  Similar to the FTOs, the Mitsubishi Cyborg R also shares the honour of being tagged.

• 

  The Nissan Sileighty finds the text next to the rear wheelarch, again on the side-on portion.

• 

  Not to be outdone, the Nissan Skyline GTS25t Type M/280 Type MR, both racing and not, bring a strangely tall S to the party.

• 

  Having the last laugh however are the Nissan Silvia K's/Q's 2000cc who give over a truncated license plate style panel to the Polys branding.

• 

  The Nissan 240SX Type S finds its tag underneath the wheel in the top left corner. The Type X variation also has the tag, though next to the wheelarch like the Sileighty above.

• 

  Most Toyota Supras use a copy of this texture, each sports the now familiar text alongside a longer, reversed 'Polys entertainment'.

• 

  Last but not least, the TVR Griffith 500 and the Blackpool B340 sport their text within the space where the headlight goes.

Mitsubishi Lancer Evolutions are singled out for special treatment. Possibly owing to the fact that the various models differ only slightly, most of their textures forwent the Polys writing in favour of identification text. Some exceptions would be the Evo II, III and IV, whose textures are devoid of any text whatsoever (note the Lancer Evolutions that had those identification text are new to GT2, except for II since the texture sheet were based on the Evo III):

• Evos not Revos
• 

  The GSR version of the Evo V sports '5N' text, presumably for 5 Normal.

• 

  The unused Evo V Rally car variation has a smaller '5N' a quarter of the way down the right side.

• 

  Evo V RS racing changes things up with a '5rs' label. It's also present on the non-racing version texture.

• 

  The Mine's Evo V keeps it in the family with a '5rs' all of its own.

• 

  Bucking the trend, the used Evo V Rally Car hides a '5Ar' to the left of the Ralliart logo.

• 

  The Evo VI GSR doesn't have the 'N' of its Evo V counterpart, instead showing 'gs' alongside the 6.

• 

  The racing version of the Evo VI GSR changes the designation again, from '6gs' to '6gr'.

• 

  Likewise and like its Evo V counterpart, the RS version has the 'rs' text.

• 

  Finally, the Evo VI RS racing and the Evo VI Rally car have '6rr'.
