F-Zero: GP Legend: Inaccessible Courses added to Story Mode

F-Zero GP Legend has 2 courses in its code that are not accessible through normal play.
*Big Blue: Calm Sea is only accessible through single-pak multiplayer, which is difficult or impossible to use with certain emulation setups.
*Mute City: Mute City II is dummied-out content, thought to be an abandoned idea for Expert variations of the Platinum Cup. It is a remake of Mute City III from the SNES game.

This patch inserts these 2 courses into story mode. Big Blue: Calm Sea replaces Big Blue: Slip Highway in Rick's, Jack's, and Zoda's stories. Mute City: Mute City II replaces Mute City: Tradition Park in Jody's and Jack's stories.

Patches for US, EU, and JP versions are included in the download. When combined with GuyPerfect's e+ Complete patch, all F-Zero GP Legend content is playable.

-=Intro and Description=-

F-Zero GP Legend has 2 fully-programmed courses within its code that are inaccessible through normal play.
1) Big Blue: Calm Sea - This course is exclusive to a single-pak multiplayer game. That is, 2 GBAs joined by a link cable with one GBA having an empty cartidge slot. When played, the track contained no music, due to the link cable data transfer limitations. While this required a specific setup on original hardware and was hard to access, it is completely inaccessible on most emulation setups.
2) Mute City II - This course is actually a remake of the SNES Mute City III. It is speculated that the Platinum Cup would have contained Expert mode variants, but this was the only track completed. It is not used anywhere in the game.

GP Legend also has a story mode, which contains a mix of Grand Prix courses and exclusive courses. This patch replaces 2 of the story mode courses that borrow from Grand Prix with the 2 inaccessible courses.

Big Blue: Calm Sea
The final chapter of Rick's, Jack's, and Zoda's stories is an anticpated race on the planet Big Blue. When you get to the race, you find out that the course is simply Big Blue: Slip Highway, a track easily accessible in the Grand Prix Silver Cup. This patch replaces Slip Highway with Calm Sea. Calm Sea has the Big Blue music added.

Mute City: Mute City II
In Jody's and Rick's story, there is a chapter where their platoon has to race against each other. The course used for this is Mute City: Tradition Park, the first track of the Grand Prix Bronze Cup. This patch replaces Tradition Park with Mute City II.

-=Patching Instructions and Compatibility=-

Apply the correct IPS patch to your version of the rom. You may apply this before or after other patches. This patch is a low-impact patches that change single bytes in-line with the code. Unless you apply a patch that targets the same story mode chapters, this will likely be compatible.

These have been tested with, and are compatible with:
Anthony Ryuki's Port Town music fix
GuyPerfect's e+ Complete patch, which unlocks all e-reader content.
Both patches are recommeded to be used in combination with this patch, as that will allow you to play all of the F-Zero GP Legend content.
