Over at the "Searching for Hidden Things in GT" Discord server, a huge discovery was recently made: @j0nny0093 figured out how to load hidden courses in Gran Turismo PSP, documenting his findings over at The Cutting Room Floor, but then we started getting the idea that GTPSP and GT5 shared some very similar code. Turns out, they do! This reveals that there is a plethora of hidden courses leftover in the game's data, most of them being classics from Gran Turismo 4, and a bunch of strange outliers from Gran Turismo 3, and even Pikes Peak from Gran Turismo 2 of all things. The Discord community compiled as much data as we could and I've compiled all of these hidden courses found in the game on a page over at TCRF as well. The list is pretty much complete, but there are still things to be tested. Below in this post are the first ever pictures released of these classic courses being played in the game: (IMAGE SIZE WARNING) Tsukuba Circuit (GT4): Test Course (GT4): Pikes Peak: EDIT: There is an overwhelming amount of messages and posts regarding "how to do this", so I'm going to quote two posts from Page 2 to answer this question for people who are posting: The Discord server welcomes anyone who wants to join, but please keep in mind that the server is more on the topic for finding hidden and unused content and less on the topic of emulation, help regarding running emulators and related subjects to that, so please keep this in mind before requesting to join the server.
