rlm@240 7
rlm@290 8 get pikachu, fight rival, deliver oak's parcel, go back to
rlm@290 9 viridian poke mart.
rlm@239 10
rlm@290 11 Perform save corruption.
rlm@239 12
rlm@290 13 switch 6th pokemon with 9th to set current-items to 0xFF
rlm@239 14
rlm@290 15 Sell 254 cancel-buttons to get a bunch of money.
rlm@239 16
rlm@290 17 buy a pokeball to repair item-list
rlm@290 18
rlm@290 19 buy 1 pokeball, 1 potion, 1 antidote, 1 parlyz heal, and
rlm@290 20 96 burn heals
rlm@290 21
rlm@290 22 95 burn heals spells out the address that will safely return
rlm@290 23 control to the pokemon kernel.
rlm@290 24
rlm@290 25 switch 5th pokemon with 9th to set current-items to 0xFF,
rlm@290 26 corrupting the item-list again.
rlm@290 27
rlm@290 28 Deposit things from your item list to get the following
rlm@290 29 pattern in the item computer. You can do this with what is
rlm@290 30 in your item list because of the previous setup.

rlm@240 60
rlm@290 61 Drop enough from rival's first character/ second character
rlm@290 62 as an item so that it is [0x7F 0xD5] instead of [0x7F 0xE1].
rlm@290 63
rlm@240 64 shift rival's name's first two characters into
rlm@290 65 mem-function-address.
rlm@240 66
rlm@240 67 now close the menu and continue item manipulations using the
rlm@240 68 newly constructed program. Starting and then canceling the
rlm@240 69 start menu activates the program.
