This is my talk page, only arbitrary code execution is allowed here.
Artificial trainer classes
NOTE: This is for English Pokémon Yellow only.
Naturally, only 56 trainers can be encountered via the trainer escape glitch (Special stats of 200-255, trainer IDs 0 to 55).
However, with arbitrary code execution, you can encounter artificial trainer classes with the routine at 3D:5FF2 with these very specific items:
1. ws m (0x63), any
2. 4F (0x59), any
3. Lemonade (0x3E), x61
4. Thunderstone (0x21), x242
5. 10F (0x5F), x1
6. X-Special (0x44), x2
7. Max Potion (0x11), x127
8. TM18 (0xDA), x205
9. Item 0x9D, x0
10. TM01 (0xC9), x33
11. Item 0xBB, x218
12. Lemonade (0x3E), x62
13. Water Stone (0x22), x4
14. Lemonade (0x3E), x(class)
15. Water Stone (0x22), x4
16. Lemonade (0x3E), x255
17. TM34 (0xEA), x88
18. TM08 (0xD0), x4
19. Poké Ball (0x04), x6
20. Soda Pop (0x3D), x33
21. Item 0x7F, x218
22. TM05 (0xCD), x132
23. Lemonade (0x3E), x201
Before you use ws m and 4F, make sure the bytes (C3, 21, D3) are located at DA7F and the bytes (C3 30 D3) are at DA64 (FA64).
Code:
For "ws m" (0x63):
- ld a, 3D
- ld hl, 5FF2
- ld bc, 0244
- ld de, DA7F
- call 009D
- ret
This code calls "FarCopyData" with its source being 3D:5FF2, the bytes to copy being 0x244, and the destination as DA7F.
For "4F" (0x59):
- ld hl, DABB
- ld a, 3E
- ldi (hl), a
- inc b
- ld a, (class)
- ldi (hl), a
- inc b
- ld a, FF
- ld (D058), a
- inc b
- inc b
- ld b, 3D
- ld hl, DA7F
- call 3E84
- ret
bytes needed at D31C:
17 63 BE 59 BE 3E 3D 21 F2 5F 01 44 02 11 7F DA CD 9D 00 C9 21 BB DA 3E 3D 22 04 3E xx 22 04 3E FF EA 88 04 06 3D 21 7F DA CD 84 3E C9 FF note: replace "xx" with the desired real trainer class ID in hexadecimal, for example, if you want to fight ゥ, A, replace "xx" with 37 (this value is hexadecimal).
additional notes: - the three bytes you placed at DA7F and DA64/FA64 are all saved with your save file.
