Regi Tombs are frozen due to the Braille wall (but may be unfrozen later?).

Trainer Hill is frozen to prevent breakage.

Trick House is frozen to prevent breakage.

Petalburg Gym is frozen, due to doors being tied to trainers (high softlock potential).

Mossdeep City Gym is frozen, due to complexity with verifying the puzzle can be completed with warps altered.

Petalburg Woods is currently frozen, but may be unfrozen later.

The Elite 4 are all frozen to enforce gym completion (but may be configurably unfrozen later?).

Littleroot Town is frozen to guarantee the player gets a Pokemon.

There are no guarantees on softlocking prevention, though several precautions are taken:

After a seed is found, map JSONs will be modified and pokeemerald can be compiled.

Current average amount of viable generated seeds is about 1 in 20,000.

The pathfinding routes do not use Cut, Fly nor the bikes. As such, it is highly likely that sequence breaks will allow faster completion.

“Completable” is defined as a series of pathfinding routes from the first gym to the last gym to the Elite 4, including required story events and in-order.

This can take anywhere from a couple of minutes to an hour.

The script will search for randomized layouts which pass completability tests.

Ensure that the repo has not already been randomized, or the script will not work!.

Edit rand_idx at the top of the file to the seed to start searching from.

Set POKEEMERALD environment variable to the path to your pokeemerald/ folder.

Install networkx and matplotlib via pip3 or similar.

Randomizes the warps in a stock pokeemerald repo.
