1 ******** Game Sequence
3 start game
5 name rival "L<PK>U<PK><PK><any-character>"
6 (0x8B 0xE1 0x95 0xE1 0xE1 0x<any> in character codes)
8 get pikachu, fight rival, deliver oak's parcel, go back to
9 viridian poke mart.
11 Perform save corruption.
13 switch 6th pokemon with 9th to set current-items to 0xFF
15 Sell 254 cancel-buttons to get a bunch of money.
17 buy a pokeball to repair item-list
19 buy 1 potion, 1 antidote, 1 parlyz heal, 2 pokeballs, and
20 96 burn heals
22 95 burn heals spells out the address that will safely return
23 control to the pokemon kernel.
25 switch 5th pokemon with 9th to set current-items to 0xFF,
26 corrupting the item-list again.
28 Deposit things from your item list to get the following
29 pattern in the item computer. You can do this with what is
30 in your item list because of the previous setup.
32 [repeat the following 25 times]
33 0xFF
34 0x01
35 [end repeat]
37 ;; Second part of program to swap item ID and quantity at
38 ;; fixed address.
40 0x00 ;; decrement HL
41 0x2B
43 0x00 ;; this starts at address 0xD56C
44 0x2A ;; save (HL)=(target) to A, increment HL
46 0x00
47 0x47 ;; save A to B
49 0x00
50 0x3A ;; save (target+1) to A, decrement HL
52 0x00
53 0x22 ;; save A to target, increment HL [(target+1) -> target]
55 0x00
56 0x70 ;; load B into target+1 [(target) -> target+1]
58 0x00
59 0xC3 ;; first part of absolute jump
61 burn-heal (0x0C)
62 x 95 (0x5F) -- address of Route 3 memory-function
64 [repeat the following 4 times]
65 0xFF
66 0x01
67 [end repeat]
69 ;; first part of item manipulation program
71 0x00 ;; this starts at address 0xD58A
72 0x21 ;; load target into HL
74 third rival's name character (U == 0x94)
75 x D5 -- target item address
77 0x00
78 0x18 ;; jump relative
80 fifth rival's name character (PK) (TM25) (0xE1 == -31)
81 x any
83 0xFF
84 0x01
86 target-item type (at 0xD594)
87 target-item quantity (at 0xD595)
91 Drop enough from rival's first character/ third character
92 as an item so that it is [_ 0xD5] instead of [_ 0xE1].
94 shift rival's name's first two characters into
95 mem-function-address.
97 now close the menu and continue item manipulations using the
98 newly constructed program. Starting and then canceling the
99 start menu activates the program.
