Yeah, its easy to replace the textures, and I have a complete set that I used with Grand Valley Speedway. The problem occurs when I try to make a separate zip file with a patch that includes the unsanctioned original GT banners. Most of the time the game doesn't read the patch files first and loads the ones in the main map's zip file. I deliberatly setup the S-turn and several other spots like after the first tunnel to be like a rally stage, where there's little room for error if you drive too aggressively. There are subtle traps setup everywhere to destroy cars. Its quite a shock if your used to GT's smooth invisible boundaries and this race track leverages the game's physics to get the most fun and challenge. Once (if ever) there is full network multiplayer, Id like to make a safe version for league racing, with more barriers and safe runoffs, but for now it seems prefect for keeping things interesting.
