You can maintain certain effects by executing arbitrary code every frame. First, you need to perform the following setup.

The game executes address FF80 every frame, so we can change this with arbitrary code execution for setup.

First, change the contents of addresses D41B-D436 (Gold/Silver) or D6E9-D708 (Crystal) as follows:

D41B~D436:
                                 CD 22 D4 3E C3
18 83 AF DC 64 D8 AF DC CB D7 AF DC 7A D6 AF DC
89 D6 AF DC E3 D7 C9

D6E9~D708:
                           F0 70 D6 F9 CC F4 D6
3E C4 18 83 AF DC 1F DB AF DC 86 DA AF DC 01 DA
AF DC 10 DA AF DC 9E DA C9

Next, change the contents of addresses D813-D826 (Gold/Silver) or DACE-DAE1 (Crystal) as shown below, then move the cursor to address D813 (Gold/Silver) or DACE (Crystal) and press SELECT+A to execute arbitrary code:

D813~D826:
         3E 18 21 80 FF 22 36 76 21 1B D4 11 F8
FF 01 07 00 C3 D6 30

DACE~DAE1:
                                          3E 18
21 80 FF 22 36 72 21 E9 D6 11 F4 FF 01 0B 00 C3
F2 2F

If the arbitrary code execution succeeds without freezing and the address FF80's content changes to 18, the setup is successful. Note that persistent effects are lost when resetting the game, so you'll need to rerun this program after restarting if you want to use persistent effects again.

To phase through walls by ignoring collision detection, change the contents of addresses D864-D871 (Gold/Silver) or DB1F-DB2C (Crystal) as follows:

D864~D871:
F0 A6 CB 4F C8 AF 21 97 CE 22 22 22 77 C9

DB1F~DB2C:
F0 A4 CB 4F C8 AF 21 3E D1 22 22 22 77 C9

Then execute the following program to enable wall phasing when pressing the B button:

21 22 D4 36 37 C9

21 F4 D6 36 37 C9

The game will freeze if you cross map boundaries into undefined maps. Buildings use collision detection for exits, so be sure to release the B key before approaching exits.

To catch the trainer's Pokémon, change the contents of addresses D7CB-D7E2 (Gold/Silver) or DA86-DA9D (Crystal) as follows:

D7CB~D7E2:
                                 21 08 D1 3E 02
96 C0 47 F0 A6 E6 04 C8 4F 35 11 07 CC 21 E3 D0
C3 D6 30

DA86~DA9D:
                  21 5E D2 3E 02 96 C0 47 F0 A4
E6 04 C8 4F 35 11 29 C7 21 39 D2 C3 F2 2F

Then execute the following program⁠1⁠. During trainer battles, pressing SELECT will turn the battle into a wild Pokémon encounter, allowing you to catch the trainer's current Pokémon:

21 26 D4 36 37 C9

21 F8 D6 36 37 C9

The caught Pokémon will have a PP of 0, but will have the same move set as when the trainer used it. The battle ends when you catch or defeat the current Pokémon. While you won't receive any prize money, the trainer is considered defeated.

Be careful not to hold the SELECT button when starting a trainer battle.

To make all wild Pokémon appear as shiny, change the contents of addresses D67A-D688 (Gold/Silver) or DA01-DA10 (Crystal) as follows:

D67A~D688:
21 08 D1 CB 46 C8 21 E7 D0 36 FA 23 36 AA C9

DA01~DA10:
21 5E D2 CB 46 C8 21 3D D2 36 FA 23 36 AA C9

Then execute the following program to make wild Pokémon appear as shiny:

21 2A D4 36 37 C9

21 FC D6 36 37 C9

The values FA and AA values in the program correspond to the Individual Values of appearing Pokémon, and can be changed to make Pokémon appear with specific IVs.

To make wild Pokémon appear as specific species at specific levels, change the contents of addresses D689-D698 (Gold/Silver) or DA10-DA1F (Crystal) as follows:

D689~D698:
21 08 D1 CB 4E C0 21 DF D0 36 FB 2E EE 36 1E C9

DA10~DA1F:
21 5E D2 CB 4E C0 21 35 D2 36 FB 2E 44 36 1E C9

Then execute the following program to enable specific wild Pokémon encounters:

21 2E D4 36 37 C9

21 00 D7 36 37 C9

The values FB and 1E values in the program correspond to the Pokédex number and level of appearing Pokémon respectively, and can be changed to specify which Pokémon should appear and at what level.

The RAM Writer is normally started by using a TM. However, since TMs cannot be used during battle, you cannot normally start the RAM Writer during battle. You can change this by writing a program that starts the RAM Writer you select "やめる" after selecting a TM in battle. Change the contents of addresses D7E3-D7F4 (Gold/Silver) or DA9E-DAAF (Crystal) as follows:

D7E3~D7F4:
         FA DF CE FE E1 C0 FA F6 CE FE D4 C0 3E
0D EA 14 CF C9

DA9E~DAAF:
                                          FA 68
CF FE D0 C0 FA 7F CF FE D4 C0 3E 0D EA 9D CF C9

Then execute the following program to enable using the binary editor during battle:

21 32 D4 36 37 C9

21 04 D7 36 37 C9

To stop the persistent effects mentioned above, execute the following program:

To use persistent effects again, execute their respective activation programs.
