Grass surf English port - death warp method

This trick is possible with "death warping" (https://www.youtube.com/watch?v=5RevIIYYoVc), which is escaping from a Trainer by getting a wild Pokémon encounter in a Trainer's sight but losing the wild battle (so the Trainer has to be next to a grass tile or in a cave). A way to work around the luck-based element to it is to save the game one step before the tile so that if you don't get an encounter you can reset the game and try again.

Unlike a normal Trainer-Fly, in "death-warping" neither the start menu (which is normally enabled by fighting another Trainer or changing boxes) or the ability to encounter a Pokémon on the original route (which is normally enabled by fighting another Trainer or being guided by the museum guide in Pewter City or watching the Hall of Fame ending sequence) is disabled.

If the player immediately returns to the original route without encountering a Pokémon and the start menu was the last menu opened, the start menu will open and an encounter with the original Trainer is stored, to be loaded when the menu is closed or the glitch item "8 8" is used.

Here are steps for this glitch that involve death warping rather than Trainer-Fly:
1) Death warp from an applicable Trainer, such as the Bug Catcher in grass on Route 6. There are others, however, there is a risk that 8 8 might freeze the game on another route.
2) Return to Route 6 and use "8 8" to start a battle with the Trainer.
3) Once the battle starts, use 9F. The start menu will pop up.
4) Save and reset. After you save and before resetting, an encounter will likely appear based on the Special stat of the enemy Pokémon on the field. This is normal.
5) When you reload your save, the waves in the water should no longer move. This is a sign that the glitch worked - the game is supposed to set the water encounter rate to 00 but left it as it was from when the Trainer data overwrote it and the water encounters.
6) Exit the start menu and use the walk through walls item to get into water without surfing (as surfing doesn't work anymore for some reason)
7) Move around on the tile to find Pokémon that were not on the route, based on the last Trainer.

This alternative method to pull off the grass surfing glitch port sadly does not allow for total freedom of which Trainer you get; hence there is less potential of manipulating the Pokémon you encounter in the water (though it can be used without needing a Pokémon with a high Special stat).

There is still room for manipulation as one of the encounterable Pokémon in the table (water Pokémon 6) is based on enemy Pokémon 1's Trainer ID byte 1, which is actually equivalent to the player's Trainer ID byte 1. The Trainer ID byte 1 (D359) can be manipulated by changing item 30's quantity in an expanded item pack obtained with dry underflow glitch.
