     3 

     4 start game

     5 

     6 name rival "<space><PK>G<PK>G<PK>" 

     7 (0x7F 0xE1 0x86 0xE1 0x86 0xE1 in character codes)

     8 

     9 get pikachu, fight rival, deliver oak's parcel

    10 

    11 buy 5 items from viridian store, with the last one being a

    12 burn-heal.

    13 

    14 Perform save corruption.

    15 

    16 move one of the other items that wasn't destroyed (but not

    17 burn-heal) to the money counter to get a bunch of money.

    18 

    19 buy 94 more burn heals.  95 burn heals spells out the

    20 address that will safely return control to the pokemon

    21 kernel.

    22 

    23 deposit the cancel item one at a time into the item computer

    24 35 times. 

    25 

    26 deposit 95 burn heals into item computer. This establishes

    27 the return point for the program so it doesn't crash the game.

    28 

    29 throw away the second character of rival's name until it is

    30 equal to D5. Now the first two characters of rival's name

    31 spell out the start point of the program that will be

    32 constructed in the item computer.

    33 

    34 throw away the fourth and sixth characters of rival's name

    35 until it they are equal to D5. The (thrid and fourth) and 

    36 characters of rival's name now spell out the target item

    37 which we will manipulate in the item computer.

    38 

    39 toss the zero items past the map data in item memory to

    40 spell the following assembly (using underflow) and combine

    41 with rival's name like so

    42 

    43 0x00

    44 0xFA -- first part of "Load A from Literal address"

    45 

    46 third rival's name character

    47 fourth rival's name character -- target item address

    48 

    49 0x00

    50 0x3C -- increment A register

    51 

    52 0x00

    53 0xEA -- first part of "Save A to literal address"

    54 

    55 fifth rival's name character

    56 fourth rival's name character -- target item address

    57 

    58 0x00

    59 0xC3 -- first part of "Absolute Jump to literal address"

    60 

    61 burn-heal

    62 x 95      -- address of Route 3 memory-function

    63 

    64 

    65 shift rival's name's first two characters into

    66 mem-function-address. 

    67 

    68 

    69 

    70 now close the menu and continue item manipulations using the

    71 newly constructed program.  Starting and then canceling the

    72 start menu activates the program.

    73
