'ws m' code by Wack0: Playing Pikachu's Beach without a Surfing Pikachu
Read description for more information:
ws m (hex: 63) is an item in Pokémon Yellow that executes code from the number of Pokémon in the current box, and using TheZZAZZGlitch's 'bootstrap code' (http://forums.glitchcity.info/index.php/topic,6638.msg189586.html#msg189586) you can redirect the program to the 3rd item in the player's bag (D321).
Wack0 and I worked on a code to play Pikachu's Beach from anywhere using 'ws m'. Thanks to the Japanese website 'Pokemon Analysis' for documenting the location of part of the Pikachu's Beach (ROM 3E:4071), I was able to find an equivalent in the English Yellow (ROM 3E:407A) but it turned out this didn't cover the code for things like changing the music and loading the 'HP' properly, so Wack0 looked into it for me and found that the code really starts at 3E:4000. (more information here: http://forums.glitchcity.info/index.php/topic,6638.msg192587.html#msg192587). He then worked on making a code for 'ws m' to make the program jump there and change the bank.
