Seeing as how literally every other game here (apart from GT6, but that will have its own thread soon enough) has its own thread here regarding this subject, I think it's about time that Gran Turismo 5 receives its own thread as well. Spurred off from the Gran Turismo 4 / PSP Course Found in Gran Turismo 5 thread, lots of other discoveries are being made as well but are being posted on that thread, so the purpose of this thread is to keep any other discoveries organized. Also, if other users discover content that fits the criteria, it can be posted in here as well. The Index December 6th, 2012 | One of the first ever published posts about unused/hidden content in the game; discoveries include lots of unused game items, the Red Bull X2010 JP Flag Color and the Red Bull X2010 5G models, evidence that the Nissan R92CP was meant to be a Premium model, the Secret Settings in the Options, and lots more July 10th, 2019 | Courses from Gran Turismo 4 / PSP found inside Gran Turismo 5's game data, mostly playable July 16th, 2019 | Thumbnails of "wedding cars" possibly from Gran Turismo 5 Prologue found inside game data July 16th, 2019 | Map asset for "pikespeak_ps2" hidden/unused course was added in Version 1.02 of the game July 16th, 2019 | Unused Course Maker templates "template02" and "template04" found intact and playable in the game data August 8th, 2019 | Prototype version of the game "GT5 Demo 2010" decrypted September 19th, 2019 | Previously non-working hidden/unused course originating from Gran Turismo 4 "Hong Kong" made functional by anonymous user; culprit was the camera information file October 20th, 2019 | User @j0nny0093 discovers that reverse layouts of the hidden/unused GT4/PSP courses in GT5 still have data intact; culprit is the collision files for these courses November 4th, 2019 | LAN multiplayer functionality discovered by changing game configuration January 13th, 2020 | Turn signal and hazard lights functionality in-game pinpointed by @elston87, tested to be working by @j0nny0093; only one car so far has this function, the Aston Martin DB9 Coupe '06. Any other new discoveries can be posted in this thread, and will be appropriately added to the index. Timestamps are from various sources that are not GTPlanet; the earlier discoveries were found elsewhere and were published to GTPlanet usually on the following day. If your post/discovery doesn't get added to the index, send me a PM or possibly someone else will tag me to get it added!
